This years Alfred Curtis Memorial lecture “The Digital Telescope Concept” was presented by Professor Don Pollacco from the University of Warwick. If you click on the link https://britastro.org/wp-content/uploads/2024/03/Winchester-Bios-Abstracts.pdf you can read the biographies and abstracts of all the speakers and their talks in the order they were given.
On Saturday morning CMHASD member & trustee Martin Crow gave his presentation about the ExoClock Project with regard to how citizen scientists are contributing to ESA’s Aerial Space Mission.
On Saturday afternoon some white light solar observing /imaging was possible through the thin cloud.
NEVER LOOK AT THE SUN DIRECTLY. Please click here for solar observing safely.
Back by popular demand were Eric and Ernie (CMHASD members Steve Floodgate & David Grist) who made an appearance at the BAA members session on Sunday afternoon to promote and drum up support for New Scientist Live at ExCel London at which they and other CMHASD members helped.
Also David Grist is now a fully paid up member of the British Astronomical Association choir....
As night fell, observing had been planned but with cloud cover on both nights two social evenings were had instead :-)
Thank you to members Diane Clarke & Martin Crow for your help writing this post and to Diane, Martin and Simon Dawes for sharing your photos of the weekend.

Many members have been at AstroFest this weekend, but it looks like the cost of living crisis and high prices seem to be having an impact, with many retailers and manufacturers not exhibiting at AstroFest this year. At least there isn't the crush of people from past years and a bit more space to have a coffee and cake or get get some practice in docking to the ISS.

Below is a brief summary of the latest trip by CMHASD members to Kelling Heath for the Autumn Equinox Star Party written by Simon Dawes.
''10 Members, 5 pitches, 2 tents, 2 caravans, 1 camper van and a lodge set the scene for a damp and windy long weekend.
If you decided to go to the Autumn Kelling Heath star camp based on the weather forecast, you would never leave Crayford; fortunately us seasoned star campers know better than to believe the forecast.
Wednesday: Cloud, Wind and Rain.
Four of us arrived in the rain, setting-up camp in a brief gap in the weather and headed to Honor’s lodge for a very welcome evening meal.
Thursday: Cloud, Wind and Rain.
Some of us headed out for a walk to the beach stopping for tea and cakes at the village cafe, a cloudy night saved by us zooming into the Barry Kellet lecture.
Friday: Cloudy, Windy, and a clear night.
The short term forecast suggested a clear night, the clouds parted early and we weren't disappointed, we had views through Dominique's a very nicely set-up 3” Refactor, Keith’s 10” Dobsonian, Simon’s 12” Dobsonian, Julian’s 20” Dobsonian, and some very nice 4” Binoculars from a nearby pitch.
It was too windy for imaging early on but the wind died down and David did a good job imaging using a Samyang 130mm Lens on an HEQ5 mount – possibly overkill – but the results spoke for themselves.
We packed up at about 3:30 am.

Below are images by Jim Burchell. All images where taken with a Pentax KP attached to a Skywacher star adventurer. All the images are single frame images.
Saturday: Dry, partial cloud during the day, mostly cloudy at night
We visited the trade stands, being careful to leave our wallets behind. Julian had some wonderful views of the Sun in his Ha telescope a modified PST.
Sunday: Dry
We packed up and headed home.''
Plus Kevin had a cute little visitor one night to his tent :-)
2023 October 21/22
Aristotle University of Thessaloniki, Greece
3rd ExoClock Annual Meeting
CMHASD trustees Martin Crow, Simon Dawes and Dr Mike Rushton attended the 3rd Annual Conference of ExoClock in Greece, a project to improve the ephemeris of exo-planet transits for the European Space Agencies, Aerial Mission, due to launch in 2029.
During the conference Martin and Simon were awarded ‘Silver Awards’ for reaching over 100 successful ExoClock observations. Congratulations Martin & Simon!
Below are 2 accounts of the trip written by Martin and Simon.
Martin wrote ''When this year’s annual meeting was announced and that it was going to be in Greece, it felt that it was important to attend in person. The previous in person meeting, the first one since lock down, had been held at UCL in London. Because the project is international the annual meetings are a rare opportunity to meet other like-minded observers who we only normally see over Zoom.
Simon (who is also a regular contributor to ExoClock) and Mike (who is interested in the project and has done some transits with his EvScope) also come along.
We flew out on the Thursday which give us a free day to explore Thessaloniki before the weekend meeting. Our hotel was well placed in the middle of Thessaloniki although it was on a busy road junction.
I knew nothing of the place before we went. It is steeped in history and in cats. Yes cats. They were everywhere.
The Museum of Archaeology showed off the amazing finds of stuff made in and around Thessaloniki generally between 2000 and 2400 years ago. Delicate pottery and intricate gold jewellery, which had only survived because they were grave goods, were on display. The workmanship was incredible.
We also visited the White Tower (Middle Ages), the Rotunda (Roman) still with its domed roof and some of the massive city walls.
The weather was warm and there were plenty of restaurants to choose from. We took advice from the locals and kept away from the main tourist drags. The food was good, not expensive, and the portions were large. What not to like – providing you are not a vegan or veggie – there was a lot of meat.
The location of the meeting was just a 15-minute walk from the hotel.
The Saturday meeting kicked off with an Introduction given by Anastasia Kokori from UCL and various talks followed about the science surrounding the Ariel space telescope, the evolution of hot Jupiter's and the possible use of machine learning with charting exoplanets.
After lunch there were more talks about Ariel and ExoClock. Following on from afternoon tea were more talks relating to the ExoClock project. Some were better than others.
On Sunday the day started off with talks from students taking part in ExoClock and using its data.
There were then two short talks given by amateur astronomers. One of them was me. The brief was to talk about our experience of being involved with the ExoClock project. I described when I had first got started and the positive and supportive aspects of the software and project in general. I finished by putting it all into context, that is to say, how it allows me as an amateur astronomer to contribute to an area that is a frontier of astronomical research. Awesome.
After the coffee break there were some very interesting talks/discussions about the focus groups and, also, education outreach in schools.
Finally, after lunch, there was more on the working groups some of which, I have to say, that I struggled to follow. Plus, it had been a long day!!
What I liked about the talks was that they were not too long, mostly 20-minutes. This is a good length and kept my attention, any longer and I would be drifting off. I found most of the topics interesting with fresh information on top of what I already knew.
All in all, a very worthwhile trip.''
Simon wrote ''We arrived on Thursday evening, and after dinner at a traditional Greek Taverna (ταβέρνα in Greek) we headed back to the hotel for Tea, in time to ‘zoom in’ to the societies lecture by Paul Money on the Vikings on Mars.
The following day was dedicated to sightseeing, Thessaloniki Archaeological Museum, The Arch of Galerius, The Rotunda (also commissioned by Galerius in the 4th Century AD), The Water Front and the White Tower and finally the Roman wall. One day really wasn’t enough for the sights and sites and we only scratched the surface of what Thessaloniki has to offer.
The conference was over 2 days, most lectures being 30 minute in length and ranging from the easy to follow to the latest mathematical, statistical and AI techniques associated with the Aerial and related Space Missions. Including, in one of the talks, a description of 24hrs of wasted Hubble time due to inaccurate exo-planet transit timings, really bringing home the impact amateur astronomers can have in this field by improving these ephemeris. There were also many talks on how MSc students were using exoclock data (hopefully crediting the observers) to understand better the characteristics of these planetary systems.
Martin and I were both awarded ‘Silver Awards’ for reaching over 100 successful observations (which is approximately 1000 hours of observing and maybe 300 hours in processing when you also take into account the failures due to weather or equipment issues) by the Principle Investigator (Giovanna Tinetti) and the leader of the Exo-Clock programme (Anastasia Kokori).
We headed home on Monday morning.''

CMHASD at the BAA Winchester Weekend 2023
Written by member Honor Wheeler
The weekend started off with the majority of us meeting up at a pub for Friday lunch, although the M25 did its best to make that as difficult as possible but thankfully we all made it in the end. Then an A31 closure sent us all on a long, picturesque diversion before finally checking in at the Sparsholt College campus.
The first lecture on the Friday night, after a delicious dinner of course, was titled 'Superluminous Supernovae: Fantastic bursts and where to find them' by Dr Matt Nichol, Queen's University Belfast which was an fascinating talk on Supernovae past and present. This was followed by a trip to the campus pub for some or returning to the common room for a chance of some relaxation for others.
The Crayford Crew
A busy lecture Saturday followed starting with 'Pete & Paul's 2023 Astronomical Challenges' followed by 'OJ287 - a Black Hole Worthy of Amateur Study' by Gary Poyner BAA, 'the Electromagnetic Spectrum' by Paul Hearn BAA, a talk from Dr Alex Cameron on the 'JWST Observing Galaxies in the Very Early Universe' looking even further back in time to 13.1 Billion years and seeing one of the highest Redshifted Galaxies to date.
Before the afternoon lectures recommenced, a little Solar observing was achieved with some observations of complex groups of Prominences and Sunspots.
The Sun by Honor Wheeler
The afternoon session was presented by the BAA Mercury and Venus section starting with a look at the 'Sodium Ion Tail of Mercury' by Chris Hooker and how to image this elusive 'Comet like' tail followed by 'Observing Venus in IR and UV' in a variety of short talks by other members of the section.
Some members took the opportunity to explore the college grounds which are extensive and enjoyed some great views of the countryside seeing Deer, Buzzards and a rather stunning bird of prey known as a Red Kite.
Saturday evening and we enjoyed the Alfred Curtis Lecture, 'Exploring the Ice Giants of our Solar System' by Prof. Patrick Irwin (University of Oxford) another interesting lecture which left us with the hope that maybe we'll be visiting these enigmatic Planets sooner rather than later.
A few members then made the most of clear skies and carried out observations of Venus and its conjunction with the Hyades before retiring to the pub or the common room for discussions about the day's lectures.
The Hyades & Venus by Jim Burchell
On Sunday the day began with an intriguing lecture 'How Astronomers Can Save The World' by Stuart Eves (SJE Space) but I don't think we were quite convinced that painting an Asteroid with White Paint would save the world from an impending impact (Steve was just kidding!!)
Dr Jen Gupta followed with a lively discussion on seeing 'The Invisible Universe' and looking at how we see through the dust obscuring distant, new stars.
'Let There Be Light' followed with an extensive tour of our local star the Sun by Dr Matthew Malek.
After lunch came the Members session and the opportunity to hear about projects, imaging and observations undertaken by members but which also included a rather different lecture which brought a lighter side to the proceedings.
Steve Floodgate & Dave Grist gave us a Stella (Artois) Performance…I mean Lecture on the complex Crayford Astronomical Society's 'The Book'. You had to be there but safe to say the Members session was one everyone will remember until the end of time…! And maybe there will be a Pub at the end of time too…?
And thus the weekend was over leaving us all heavy with the knowledge gleaned from eminent Doctors, Professors and experts in their field and also filled with an amount of excellent food we just couldn't say no too.
In the end 15 members of the society managed to attend the weekend, with 2 other members who unfortunately had to cancel due to personal reasons.
Overall a thoroughly enjoyable and informative weekend with lots of information to mull over and I'm sure leading to numerous further discussions to be had until next year's BAA Winchester weekend 2024.

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.
