Competition: Image the Trapezium
In this competition we are looking for images of the Trapezium at the heart of M42, the great Orion nebula. We normally think of the Trapezium as 4 stars but in large telescopes you can make out other stars, so all you need to do is submit an image of the Trapezium with more than 4 stars.
Sounds simple, but the main 4 stars of the trapezium are bright making it difficult to resolve the other stars.
This is possible in an 8″ telescope – possibly smaller.
Tips:
- use lucky imaging with short exposures.

Here is a photo of Trapezium cluster I took a few weeks ago with my iPhone through my 102mm Maksutov scope. I think the magnification is about 100X. Don’t know ISO because it was taken with phone camera. You can see five stars. I plan to take out my bigger scope and try again. “Cheers”

Best Meteors of 2020
Almost 2000 meteors were detected in 2020, we would have had quite a few more but for the cloudy skies in August that limited the view of the Perseid’s in August.
2020 Meteor stats collated by Simon Dawes from data reviewd and analysed by the Crayford Meteor Team.
December 2020Meteor report
December was particularly cloudy, but we still manage to detect 288 meteors, 115 from the Geminid meteor shower.

Honor recently took this video of a transit of the Sun by the ISS, something she has been attempting for 10 years.
Image by Honor Wheeler This was taken using: Skywatcher ED80 refractor Canon 700D set in movie mode @50fps 2x Barlow EQ3 mount Date 2020.04.20 13:09UTC Transit time was 0.9 sec 16 frames extracted from the original video using PIPP and then the layers merged in Photoshop elements 6. Additional processing also done in Photoshop E6.
The Great Conjunction of 2020
Jupiter-Saturn conjunctions happen every 20 years (the last one in 2000.) however this particular conjunction will be especially close – the closest since 1623 and the closest observable since 1226! Don’t worry, if you miss it there is another close conjunction in 2080!
At its closest on 21st December Jupiter and Saturn will be 6 arc minutes apart (1/5 the diameter of the full moon) which is still easily discernable as two separate planets (some reports would have you believe the merge together into an ‘elongated star’)
The weather was poor on the 21st, but there was a gap in the clouds on the 20th, the images from the 20th the planets were at about 9 arc minutes vs 6 arc minutes at closest encounter.

EXO-Planet Paper features observations from two Members
Members Simon Dawes and Martin Crow have been named as contributors on a scientific paper published this week, Martin and Simon along with other amateur and professional astronomers have been observing exo-planet transits – each observation takes between 4 and 5 hours typically so is quite a commitment. Well done Mrtin and Simon and all the other amateur astronomers who submitted observations.
Abstract
The Ariel mission will observe spectroscopically around 1000 exoplanets to further characterise their atmospheres. For the mission to be as efficient as possible, a good knowledge of the planets’ ephemerides is needed before its launch in 2028. While ephemerides for some planets are being refined on a per-case basis, an organised effort to collectively verify or update them when necessary does not exist. In this study, we introduce the ExoClock project, an open, integrated and interactive platform with the purpose of producing a confirmed list of ephemerides for the planets that will be observed by Ariel. The project has been developed in a manner to make the best use of all available resources: observations reported in the literature, observations from space instruments and, mainly, observations from ground-based telescopes, including both professional and amateur observatories. To facilitate inexperienced observers and at the same time achieve homogeneity in the results, we created data collection and validation protocols, educational material and easy to use interfaces, open to everyone. ExoClock was launched in September 2019 and now counts over 140 participants from more than 15 countries around the world. In this release, we report the results of observations obtained until the 15h of April 2020 for 119 Ariel candidate targets. In total, 632 observations were used to either verify or update the ephemerides of 83 planets. Additionally, we developed the Exoplanet Characterisation Catalogue (ECC), a catalogue built in a consistent way to assist the ephemeris refinement process. So far, the collaborative open framework of the ExoClock project has proven to be highly efficient in coordinating scientific efforts involving diverse audiences. Therefore, we believe that it is a paradigm that can be applied in the future for other research purposes, too.

Meteor Report for November 2020
November 2020 was spent largely in lockdown due to the Corona virus, one thing keeping us from all going crazy is our astronomy and with our remotely operated meteor camera our members were still able to observe and had lots of candidates to look forward to, and it turned out this was our most productive November ‘since records began’ – ok the records only go back to August 2018 – so was it better weather, is COVID-19 actually space borne and arriving on the meteors, or perhaps it is just a useless fact? Personally I think it has something to do with 5G masts…
Sorry back to the report.
We observed 244 meteors, 39 of them Leonid’s and you can watch them all – thanks to our members of the meteor team – without having to wade through all the false positive sightings.
I’ve embedded the video below, but if your attention span isn’t what it was, then just check-out the highlights at the times listed below (if you click on them they will take you to the correct part of he video)

Kelling Heath Autumn Equinox Star Party
7 members of the society attended the Kelling Heath Autumn Equinox Star Party, some booking camping pitches and others static caravans. The weather was overcast with showers with long dry spells and whilst the astronomical observations were very limited between clouds it was still a great event which I’d recommend any keen observers try to book.
Meteor report for September 2020
This is the meteor report for the automated meteor camera operated by the Crayford manor house astronomical society Dartford, for the month of September 2020
This month we detected a total of 269 meteors, well over half were sporadic meteors, meteors from known showers only making a minor contribution to the total, the largest identified shower came from the September Perseids but contributed only 22 meteors to the months total
Perseid Meteor Shower Report 2020
The below video is a report for the perseid meteor shower, based on meteors captured by the semi-automated meteor camera operated by the society members.
Milkyway from my back yard competition
This is a simple competition, take an image of the Milkyway from your back garden – or close to where you live. The winning image will be the one that the webmaster is most impressed with.
Rules:
- You have to be a member of the society
- No telescopes! This is for camera and lens only!
- Must be from your location not some superb dark sky you travelled to.
- Ends November-ish
What will impress the Webmaster most?

Image by Leigh Sloamer I made an attempt at capturing the milky way last night. This is a 14 x 3 minute stack at iso 3200. I would have captured more but my new lens is a dew magnet. I also had to crop the image a bit due to amp glow in the lower left corner.
Image by John Archer Thought I would pop out and snap the Milky Way while the evening is still mild and the breeze has died down. Bit of a change from planet spotting….
Image by Honor Wheeler finally found this image of the Milky Way taken from my back garden on the evening of the 23rd of August 2014. I’d just got back from the cinema and the sky was amazing. As you’ll see it was a single shot with my Canon 1100D on a tripod, no tracking! Black and White as light pollution was an issue.

Member Observing – not so isolated
We have had some lovely clear and moonless nights the last couple of days and on top of this few contrails from planes making the sky ideal for observing, and whilst alone with your telescope or binoculars you can still share your experiences using our WhatsApp groups, just contact committee@crayfordmanorastro.com if you want to be added…
Here is a selection of member observations shared over the last few nights.
Image by John Archer – 20s no other details provided
Image by Simon Dawes It’s been 11 years, 1 month and 5 days since I last imaged Venus, now I remember why…
Data measured by Martin Crow So my non transit resulted in showing up an error in NASA’s exoplanet archive. The mistake has now been corrected apparently. This is a good result as finding errors once Ariel is up would not be great
Image by John Archer of the ISS – no details provided
Here is a test CCD image of the galaxies M65 (left) and M66, part of the Leo Triplet, which I took last night. My guiding still needs sorting out…
Image by Kurt Appreciate this will be basic stuff to most of you, but here’s my first astrophotography effort of the full moon a few weeks back. Nothing too complex, 5inch SCT and snapped with a Pixel 4 phone.
Edited by Martin Just adjusted highlights and shadows mostly. You may already know this but it’s always worth looking from the edge of Mare Crisium to the limb of the moon. Due to libration you will see that this changes and sometimes we can see a little further around the moon.

Meteor Report for November 2019
This is the meteor report for November 2019, by the Crayford Manor House Astronomical Society Dartford.
This month we were plagued with poor weather and this is reflected in the low number of meteors captured.
In total we observed 139 meteors from 29 different showers, none of these showers was particularly active, the most active being the Leonid’s where we captured 19 meteors compared to 55 sporadic meteors in the Month.

AM or PM for meteor observations?
It is well known that you see fewer meteors before midnight than after. This is explained by the fact that before local midnight Meteors hitting the Earth’s atmosphere must be travelling in the same direction as the Earth, so the relative speed of the meteor to the Earth is smaller, whereas after midnight the Earth is passing through Meteors on the Earth’s leading edge, so the relative speed of the meteors are faster, and since the speed the meteor hits our atmosphere affects its brightness we should see more after midnight than before.
My own experience sifting through the meteor candidates from our camera and observing over long periods, suggest this bias should be easy to detect, so now that we have over 15 months of data, I thought I’d see if this bias in observations was real.
The UFO analysis software categorises the meteors into named showers, if a shower can’t be identified it is classed as a sporadic meteor. I have only used the sporadic meteors in the analysis to minimise any bias due to known meteor showers.
My (very simple) analysis suggests on average you are 2.7 times more likely to see a meteor after midnight than before, a much larger factor than I’d expected.
Plot showing the number of sporadic meteors per hour over a 15 month period as captured by the Meteor team using the Societies meteor camera. Overall you are 2.69 times more likely to see a meteor after midnight than before.
Does this reflect your experience? Comment below.
Transit of Mercury, 11th November 2019
Despite the poor weather our members were out in force observing the transit of Mercury across the face of the Sun, something that has to be done carefully to be safe.

Star gazing at Hall Place
It was horizon – horizon cloud last Wednesday for the sold out star gazing event at Hall Place, however we were prepared for this and along with comet making, we held sessions on drawing objects in the night sky and a variety of talks about astronomy. We had brilliant support from our members – thanks to all – who bought a variety of telescopes, cameras, meteorites and other displays, overall the visitors went away happy despite not being able to view the heavens.
Meteor Report for October 2019
Observation of Exo-Planet KELT 16b
KELT-16b is an exo-planet in Cygnus, member Martin Crow measured the brightness of the parent star (KELT48) in order to capture the small drop in brightness when the planet transits the face of the star, this is a very subtle observation that requires a lot of attention to detail in order to capture such a small change in brightness.
Observation of Exo-Planet WASP-48b
Exo-Planet WASP 48b is a planet discovered around star WASB 48 in the constellation of Cygnus. Member, Martin Crow measured the brightness of WASP 48, using the same techniques used for variable star observations – although the changed in brightness are very small, in order to detect the drop in brightness of the star as the exo-planet transits across the face of the star.
Observation of Exo-Planet HD 189733b
HD 189733 b is an extrasolar planet, in the constellation of Vulpecula. According to Wikipedia it is 64.5 light years away. Member, Martin Crow, used the same techniques used for observing variable stars to detect the drop in light from the parent star as the planet crossed in front of it. If you have data you want to share please contact the webmaster.

Meteor Report for August 2019
A huge number of meteors were detected in August 2019. August continues to be a bumper month for Meteors, dominated by the Perseid’s, but there are many other minor showers contributing to the number detected.
We also had our brightest meteor yet, a magnitude -5.5 sporadic meteor.
If you look at the surface plot (bottom Right) it looks like there were three independent peaks in August.

A big thanks to everyone who supported both of the recent Hall Place Solar Observing events which were an exciting mixture of hide and seek as far as the sun was concerned, but both in their own way very successful.
We had sideways rain at 1100 yesterday (18th August 2019), so we set displays up indoors for about half an hour, after which we relocated outside and never looked back.
Even the sun cream got an airing!
It was very encouraging to meet a couple of extremely bright 8 year olds asking / answering some great questions – future members I’m sure.
These things don’t happen by accident so for anyone who supported the two events with equipment, transport, setting up or engaging with the public, a huge thank you.
We will be back in the Winter for the pre- and post- Christmas Stargazing events and should consider any suggestions / fresh ideas to make these as engaging and informative as possible.
Once again, your support is greatly appreciated.

Meteor Report for July 2019
As the nights start to draw in we have started to see an uplift in the number of Meteors detected. Interestingly the Perseid’s – a well known broadly dispersed shower (peaks on 13th August) were the highest proportion of meteors from known showers.

Some members travelled to Argentina to view the 2019 Solar Eclipse, images below are from Janice McClean
Meteor Detector Report for May 2019
The short nights and poor weather have conspired to reduce the number of meteors we have been able to detect, but we still managed to detect 44 meteors, 30 of them sporadic.
Observing the Moon with our new Dobs, ‘Olivia’ and ‘Isaacs’
Thursday 6th June was clear so we took the opportunity to view the Moon using our new Dob’s affectionately named ‘Olivia’ and ‘Isaac’.
Building Dobsonian Mounts
Members Steve and Dave with some technical support from Keith have built another two Dobsonian telescopes for the society using donated Newtonian tubes, one is a 200mm F5 Skywatcher the other a 300mm F5.3 Orion Optics.
The design is the same as the previous Dobsonian mount they presented to the society last year, which is affectionately known as Anita.
The Telescopes are equipped with a ‘push-to’ system we call ‘Dob Buddy’ which was originally presented to the society by fellow member Simon. The Dob buddy allows members using an Android or Apple mobile device, equipped with Sky Safari Pro to locate difficult to find objects in the night sky with ease.
The Plans
The Dob buddy system uses an Arduino with low resolution encoders couples to the mount with timing belts, this system results in a very high resolution encoder system for a fraction of the costs (the encoders are £8!), all the heavy lifting in terms of tracking the telescopes position is managed by the Sky Safari Pro software. The limitations of the Apple IOS operating system not being able to send data over Bluetooth are circumvented by providing Wi-fi access to Dob Buddy.
Two mounts were constructed from Birch faced ply. It was decided that Anita (our first Dobsonian) was a bit heavy, so the new Dob’s were put on a diet, by cutting holes in the ply.
Parts ready for assembly.
Our Dobs are named after gifted musicians, because we used their vinyl LPs as a bearing for the azimuth mount.
The design of the mounts for the altitude bearings was changed (compared to ‘Anita’) to again reduce weight and reuse as much as possible of the old ‘scopes.
Our Dobs are named after gifted musicians, because we used their vinyl LPs as a bearing for the azimuth mount.

Double Star Measurements with a Meade 12mm Astrometric Eyepiece in 2018
Neil Webster, St Marys Platt, Kent
e-mail: ******@gmail.com
Introduction
The following measurements were made throughout 2018 using a Meade 12mm astrometric illuminated reticle eyepiece plus 2.5x powermate attached to an Altair Astro 115mm refractor (focal length 805mm, f7). The total magnification was 167.5x with a field of view of 0.3 degrees.
Fewer measurements were made this year due to relocation which finally happened at the end of February. Serious observing, measuring and imaging did not begin until the middle of April. Although St Marys Platt is a much darker site than Bromley measurements are still limited to 8.5 magnitude due to the red light in the eyepiece. However, a Southerly aspect is now available so many of the measurements are of systems previously unavailable.
Lecture by Dr Matt Smith
A big thank you to Dr Matt Smith for coming all the way from Cardiff to speak to us. Matt spoke to the Society about Galaxies, the Interstellar Medium and Black holes, including the most recent image of a black hole, during the talk Matt demonstrated how they can all be observed in both the optical and infrared wavelengths of light as these photos show.
Observing Evening 2019-04-18
Thursday, 2019-04-18 was an informal observing evening and whilst not ideal with an almost full Moon, we had lots of telescopes out and other members learning how to use the Peter Hindle Telescope.
The Pleiades, Mars and the California Nebula
In April 2019 Mars was close to M45 (the Pleiades) and NGC 1499 and this coincided with the Kelling Heath Star Party. Unfortunately at this time of year Taurus is very low, setting in the late evening making this a difficult object to image, my attempts to stack and then process with Deep Sky Stacker were hopeless, so I turned to Astro Pixel Processor (using a 30 day free trial) which has a very easy to use light pollution killer, this allowed me to remove the gradient that resulted from the very low elevation and trees that crept into the field.
Total exposure is 84 minutes, from 30s subs. Tracking was achieved with an iOptron Star tracker, camera was a Canon 600D with a full spectrum mod and a CLSCCD clip-in filter.
Occultation of the Beehive by the Moon
Kelling Heath Star Party Spring 2019
4 Members and 2 ex-Members travelled to the Kelling Heath Star Party, this star party has notoriously poor weather, but on this occasion we were blessed with reasonable views on Wednesday night and clear skies from dusk ’till dawn on Thursday Night, Friday Morning.
Many, many objects were observed with Keith’s 10″ Dobsonian and Simon’s 12″ Truss Dobsonian, Julian and another Simon both allowed us to view objects with their 20″ Dob’s.
Apparently the food was epic…

Meteor Report for March 2019
Meteor Camera Results for February 2019
100 meteors were detected by the meteor group in February 2019, 70 of these were sporadic and the remainder from minor showers.
Observing Evening 2019-02-21
We had a clear night on Thursday 21st February 2019, and before the Moon rose a few members had a go at the Orion Star Count, showing the diversity of eyesight and experience in our group.
The moon rose above the trees as a golden gibbous Moon and some of our group took to observing it with one of the Societies telescopes, affectionately known as Anita.
On the right is an image from Honor Wheeler taken through Anita, a Fuller Scopes 8″ F8 recently converted to a Dobsonian by a couple of our members.
Other members were experimenting with the new CCD camera purchased by the society for the Peter Hindle telescope, a 16″ LX200, using the F3.3 focal reducer we got a wide field view of the Orion nebula (M42) and M1 the Crab nebula.
Another member, Leigh Slomer, was experimenting with his Skywatcher Star Adventurer, DSLR and a 70-200mm zoom to capture images of M42.
Meteor Repoprt for January 2019
A cloudy January resulted in a small number of meteors detected, 97 in total, most sporadic, but we did detect 20 Quadrantid’s and identified meteors from 17 different showers.
If you want to join in and help with the observations please contact Janice.
The Moon, Venus and Jupiter in the morning sky
We were treated with some lovely clear skies in the mornings of January 2019 and members were able to capture a few images of the conjunction of the Moon, Venus and Jupiter.

Meteors Detected in December 2018
Our automated meteor camera and meteor team, detected 239 meteors in December, despite the cloudy weather, 60 of these were identified as part of the Geminid meteor shower. The brightest meteor detected was a magnitude of -1.8. During December we identified meteors from 22 different showers, but the geminids was by far the strongest.
Below is a video of the meteors detected by the meteor camera operated by the society, in December 2018, the meteors are ordered by brightness based on analysis by UFO analyser.
46P Wirtanen
Comet 46P Wirtanen was billed to be brighter than ever this apparition and when at its brightest it would be passing within 1 degree of M45, however the UK weather conspired against us, some members got images from outside the UK and others from before it reached its brightest, but our visit to Ashdown forest was cancelled due to 100% cloud cover and rain.
On Thursday 13th December 2018 many members observed the comet at the Dick Chambers Observatory, through binoculars (a very faint fuzzy blob only visible with averted vision) and through the 16″ Peter Hindle telescope.

I’ve been getting some practice with deep sky stacker, not as scary as I thought here is my first attempt using it to stack some images of the comet.
Image by Honor Wheeler
I’ve been lucky to have imaged the comet twice myself, once on Friday 7th & again on Sunday. The seeing has been pretty poor but it was just visible in 10×50 binoculars and looked pretty good in my 72mm refractor and 40mm eyepiece.

Astronomy Outreach with Sutton-at-Hone School
We welcomed the Children of Sutton-at-Hone Primary school to the Dick Chambers Observatory on the 12th December 2018. They had a chance to look through the Peter Hindle telescope and from the photos it looks like they had a great time, whilst learning a bit about the science of Astronomy.

Meteor Observations 2018 October
October saw us identifying 308 meteors from 32 different showers, the October Draconids and the Orionids being the most interesting.
The brightest meteor was -3.7 vMag
October Draconids Report
21 October Draconids were identified in the charts below you can see they are a very narrow peak, suggesting a narrow stream of dust the Earth is passing through. The average magnitude was 1.
Ground map of the Draconids showing the meteors that were triangulated with the Nemetode group, our observations are the ones detected by the ‘Dartford’ Observatory
Orionid Report
We identified 53 Orionids, peaking on the 21st October and an average magnitude of 1
Below is a 15 minute video of all 308 meteors verified in October.

Back to Basics Workshop
We hosted The 2018 British Astronomical Association Back to Basics workshop on 6th October.
These workshops are great for beginners just starting out in astronomy and wanting to learn how to use their telescopes or get started in Astronomy and over 50 people turned up – well done and thank you to all the Crayford Members who helped out.
The 2018 Perseid Meteor Shower
The society run an ‘almost automated’ meteor camera, if you want to be part of the meteor team checking the results every morning then please speak to the coordinator – Janice.
A total of 535 Meteors were captured, with 340 of them being Perseid meteors. Below is a video of the 20 brightest meteors during August.
Summary of the report sent to the Nematode meteor group.
The Nematode group were able to match 11 of our meteors with observations from other observers in the group producing these orbits.

2019 Calendar
Some of you who were present at the Pavilion on the 29th of March will be aware of the following changes to the Society’s Calendar rules. Each month will now consist of a collage of member’s images rather than just one per month.
The Calendar size will also increase from 21 x 28cm to 28 x 37cm picture size to accommodate the collage of images, I am unsure how many images can be accommodated per page but it may be between 6 to 8, actual numbers TBA. Price TBA.
Rather than the list of 4 groups such as the Moon, Sun, Deepsky etc. there will be a list of ‘Targets’ for member’s to photograph or sketch.
Important: Image/s to be submitted for the 2019 Calendar must have been photographed or sketched after the 1st of January 2012 but no later than 8pm (GMT) on the 3rd of October 2018.
(All images for the 2020 Calendar will need to been photographed or sketched AFTER the 3rd of October 2018 but before the 2nd of October 2019 so keep this in mind when submitting your images).
DON’T FORGET TO READ THE RULES!
PLEASE DO YOUR BEST TO TAKE PART, THANKS.
Target images for the 2019 CMHASD Calendar are as follows:
1. Earthshine
The Moon’s shadow side can often be seen when the young crescent Moon is visible. Images must show the Moon with the shadowed side also visible
2. A Rainbow
Images can be an Arc or a portion of the Rainbow.
3. The Planets
Images can be of any of the Planets (not the Earth that would be cheating 😉
4. Lunar and/or Planetary Conjunctions
Images can be of the Moon in conjunction with Planet/s or a planetary line-up of 2 or more Planets.
5. The Orion constellation
Images that show the Orion constellation in full as the left image or as the image on the right with the four stars Betelgeuse, Bellatrix, Saiph and Rigel at each corner.
6. Lunar Eclipse
A Lunar eclipse will hopefully be visible on the 27th of July but any images photographed or sketched after the 1st of January 2012 can be submitted. The Moon partially or fully eclipsed will be acceptable.
7. Atmospheric Optics
Images of any of the following: Solar Halo, Sundogs, Circumzenithal Arc, Cloud Iridescence and Crepuscular Rays etc.
8. The Andromeda Galaxy
A close-up image of this wonderful Galaxy.
9. Sunset or Sunrise
Any photograph or sketch of a Sunrise or Sunset over land or water.
10. Lunar crater Copernicus
A close up of the crater Copernicus photographed or sketched using a Telescope or a Telephoto lens.
11. Sunspots
Images of Sunspots in White Light or a projected image only, not H-alpha (as only a few members have H-alpha telescopes).
12. Ursa Major constellation
Images of the whole constellation or the Plough will be acceptable.
13. A Full Moon
The Moon must be between 98 – 100% to qualify for this Target, you’ll need to make sure as I will check the date and the image was photographed or sketched.
14. The Pleiades and/or the Hyades
An image of either the Pleiades or the Hyades or an image of them together.
I am aware there are 14 Targets, not everyone will be able to image all of the Targets so hopefully this way everyone will be in with a sporting chance of obtaining at least one image for the Calendar.
Rules: And please make sure you read them!
- You may only enter one image per category.
- Sketched, Single, Multiple Stacked or Mosaicked images are acceptable, Composite images are NOT acceptable.
- All images entered must have been Photographed or Sketched by the person entering the image/s.
- If too many images (maximum numbers TBA) are entered for one ‘Target’ then a vote will be taken on each image and the images with the most votes will be included in the Calendar.
- All images MUST have been taken AFTER the 1st of January 2012 but before 8pm (GMT) on the 3rd of October 2018.
- The two ‘Targets’ with the least number of images received will not be included in the Calendar.
- Images can be taken using another member’s telescope but the camera used MUST belong to the member submitting the image/s.
- Poor quality images will have to be omitted so make sure the image resolution is good enough for printing.
- All images MUST be submitted to this email address: honor . draconis @ talk21 .com (remove spaces) BEFORE 8pm (GMT) on the 3th of October 2018, no exceptions.
When emailing your images please use the email subject heading ‘CMHASD CAL2019’ that way I can save the images easily all in one place!
Small print – Feel free to ask me any questions that are not covered by the rules but if you do ask me a question that IS covered by the rules…then I’ll know you didn’t read them! Simon, Martin, Jim….! [this is scandalous Ed.]
Astronomy Fun Day at the Priory Centre Dartford
The Society took part in an Astronomy Fun Day on Saturday 25th August 2018 at the Priory Shopping Centre to promote Astronomy, and encourage locals to visit the shopping centre, the day was well attended and along with CMHASD was an inflatable planetarium. During the day we were promoting the BAA Back to basics workshop we are supporting in October.
Solar Observing at Hall Place – August 2018
The Society were at Hall Place on Sunday 19 August 2018 showing members of the public the Sun using safe observing techniques and talking to people about Astronomy in general. Whilst there was a fair amount of cloud about and the Sun was playing ‘hide-and-seek’ the day was a massive success.
