The programme for 2017/2018 is now on the site!
Our next meeting Friday 19th May is all about imaging. We will start with a show-and-tell session where you are invited to bring along kit/images/anecdotes/advice etc. to share your experiences of astronomical imaging — both good or bad.
The main talk will be on “Image Processing” by Steve Hill which will look under the hood to see what is really going on when you manipulate image data.
Our last meeting of this season will be our AGM, followed by member talks.
Pressing issues:
- A new treasurer needed
- Membership card image needed
- Talks needed
If you can help with any of these, please let the chairman know!
If you enjoyed Jonathan Gale’s talk on asterisms and want to follow things up, here is a link to his finder charts:

Here are the links that Steve has/had in his talk on the Science of the Solar System.

I have updated the programme with the full title for January’s talk: Jonathan Gale will present “Patterns in the Sky – Exploring and Observing Asterisms”
Let us know (mail chairman at beckingtonas.org) if you are coming to the Christmas Social. This is a fun-filled members (and family/partners) evening and will feature food, quiz, raffle, feel the sock and live music and maybe more.
Our AGM is Friday 20th June. Mike Witt was scheduled to present his talk “Moons of the Solar System”, but unfortunately he has been taken ill and may not be recovered in time. We will make alternative arrangements for a talk to accompany the AGM.
This site has a very handy field of view calculator:

Now you don’t need to guess how much your camera will see.
Many thanks to Bob Mizon for his entertaining and educational talk. Several members requested that we make the list of ten targets for light-polluted astronomers available, so here goes:
| Object | Type | Where | Finder |
| NGC752 | Open Cluster | Andromeda | Track right from the base of triangulum |
| Gamma Andromedae | Double Star with high colour contrast | Andromeda | Last bright star in Andromeda moving up from Pegasus |
| Kemble’s Cascade
The Wristwatch and NGC1502 |
Asterism; star chain and includes an open cluster | Camelopardus | Find Perseus then extend a line Algol to Mirphak by approx 1.5 the distance |
| h3945 | Optical (line of sight) double with high colour contrast | Canis Majoris | Find Sirius. Track down to delta (Wezen). The double is up and left from there. |
| Y Canum Venaticorum
La Superba HIP62223 |
Red star | Canes Venatici | Approx halfway between Cor Caroli and Phad (in the Plough) |
| NGC457
The Owl (Stick Man) |
Open Cluster | Cassiopeia | Extend line from epsilon to delta by about half again. |
| R and T Coronae Borealis | Variable stars | Corona Borealis | Star chart recommended |
| Sigma Draconis | Star with high apparent velocity (2.3″ per year) | Draco | Near epsilon |
| Stock 4 | Open Cluster | Perseus | Find double cluster and use a pointer — 7 degrees away on same declination |
| NGC7331 | Sc Spiral Galaxy with off-centre nucleus | Pegasus | Consult a star chart |
