Around 30 people attended the February meeting of Rosliston Astronomy Group.
Ken Critchon gave a great talk on hisCekestron 11 inch EdgeHD telescope. He bought this mammoth beast along with him. It is the first scope I have seen that makes a DSLR look like a tiny camera on the end and the only one which uses a Takahashi as a guiding scope (I am not entirely fair – he also uses it for wife field images).
After Ken’s talk, I showed a video from Astrofest 2017 in London with special guest star Jon Curshaw, the impressionist and friend of the late Sir Patrick Moore.
We had a longer than usual coffee break to give members a chance to chat and meet new friends.
Then several members gave short talks on items of interest in astronomy – including books, hardware and websites – something new for the club and a great success!
Ken giving his talk:
Ken with his telescope:
Ken talked about periodic error during photography and other advantages of the EdgeHD and it’s dedicated mount for astrophotography:
Roger talked about his Bresser Mikrokular camera. He showed us his homemade telescope from part binocular and part drain PVC tube:
Peter Simkin discussed astrophotography using DSLR in light polluted areas:
Geoff Dryland talked about his favourite book on process astrophotographs:
Andy McIntosh bought in three books that really made a difference to him:
Stephen Sanders discussed his favourite book about Greek mythology related to the stars:
Kathy Hassell talked to us about her favourite internet resources:
Finally, I bought along a box of bits and pieces that interested me.
Club member reviews at end of night:
1. Length of session shorter than normal – widely liked.
2. Variety was also liked.
3. Thumbs up for short member presentations – but not wanted every month.
4. Astrofest review – some members liked this video, others less do – seemed to depend on whether members were type that liked to go to astronomy conferences. Speakers weren’t that loud and this made it difficult to hear. Also directional microphone used by Andrew should be supplemented with lapel microphone for himself so he can be more easily heard. For those that did like the video they felt its length was fine at 15 mins but would not have wished it to be any longer in length.
5. Jon Curshaw video – although funny unfortunately it was difficult to hear -unlikely to be able to overcome this problem and hence avoid such videos in future.
6. In spite of above, the evening was greatly enjoyed and there were requests to repeat it at some stage in future.
