We are a very active society, meeting at least once a week, please check out our programme for details of upcoming events.
Dartford Grammar School Astronomy Club – Virtual Observing Session
Our society currently supports the Dartford Grammar School Astronomy Club, and on the 25th January 2021 we held a virtual observing evening using Simon’s observatory.
The students really enjoyed the evening
‘The boys from last night have been on the google classroom leaving you rave reviews’
‘Last night blew their minds! They loved it.’

The BAA Winchester Weekend comes to Crayford (hopefully)
Correction: It’s not a weekend (just Saturday Afternoon) and it’s not at Crayford (it’s at the Pavilion Sutton-at-Hone).
The BAA are running a virtual ‘Winchester Weekend’ – and COVID Restrictions permitting (i.e. restrictions and social distancing in London and Kent have been lifted) – we intend to add a little of that Winchester magic (OK it’s food, drink and conversation) to the proceeding by streaming it at the Pavilion Sutton-at-Hone.
Price: (to cover costs only) £10 per person – on the door – cash only (the chip shop only takes cash)
(Fish & Chips is £7.80 at my local chippy, the rest is for cake, biscuits, milk, tea and coffee.)
Date: 10th April 2021 13:00
13:00 Registration: (Tea and cake)

Observing (weather permitting)
At the moment I’m canvasing who might be interested, no commitment at this stage, just to see if it is worth taking further, closer to the event I’ll ask for confirmation and provide a menu.
This is a ticketed event, please contact the webmaster@crayfordmanorastro.com if you are interested in attending (no commitment at this stage)
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.
A brief introduction to Astronomy
Recently Mr Martin Crow, gave a talk entitled “A brief introduction to Astronomy” (The edges of the Jigsaw) for some of the societies new members, to help them better understand the “Jigsaw that is astronomy”.
Martin spoke amongst other things about.
· Measuring astronomical distance by using astronomical units (au) & light years,
· The spectrum of stars to determine their chemical components,
· Looking at objects with different parts of the electromagnetic spectrum i.e. infrared, white & Ultra- violet light.

EQ6 Locking Power Mod
The EQ6 is known for its power connector coming out or momentarily disconnecting, which is not something you want happening in the middle of an imaging session. I’d previously replaced all my power connectors to a type with a locking collar and decided to mod my EQ6 so that all my gear uses the same connector. This is not a particularly hard mod if you are confident around electronics and a soldering iron, but it will obviously void your warranty. You have to choose where to fit the connector carefully to avoid any components on the motherboard. Tapping onto the 12v on the board is pretty easy but worth checking with a multi-meter.
The Moon Rochester
Gary organised a trip to Rochester Cathedral to view the huge 3D moon that is touring the UK and to hear a lecture on the moon.
AstroImageJ Demonstration
We had an informal meeting over Christmas where Martin took the members through using AstroImageJ (AIJ) he covered the following…
- Loading an image
- analysing stars in an image
- plate solving an image
- batch processing images to calibrate them
- aligning and stacking images
- photometry on a sequence of images

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.
