Those members of the group not away for the bank holiday weekend turned up on a rainy evening to hear excellent talks by teo of our own members: Peter Hill talked about radio meteor detection and the second talk was on meeting a UK astronomer by Paul Bertenshaw. This represents a new format to the evenings with separate before and after coffee speakers and went down well with everyone there. In the past a number of our members have used the opportunity to meet astronomers when they have given talks or hosted dinners in the UK and it was fantastic to hear Paul’s excitement as he talked about the experience and see His photos with the great man! I think I will book for the next one….
We have also made a decision to incorporate a members social time between 19:30 and 20:00 for the next three months, although everyone needs to ensure they arrive by 20:00 as the forestry centre entry barrier goes down at this time.
New YiHUA power supply purchased from ebay for use witj LOMO Polam microscope. Unacceptably loud noise when turned on – I can’t imagine using my microscope with this racket in the background!
Ebay has finally yielded some new tougher bolts and replacement battery for my mount so I couldn’t resist the lure of some clear skies on Sunday night. Given that it was a school night and it didn’t get dark enough until after 11, I thought I’d try and do it Roger-style with shorter exposures on my little ZWO camera (sadly I didn’t have any double glazing facing the right way for this).
As well as borrowing Roger’s approach I also borrowed one of his recent targets as I’m quite taken by the Needle Galaxy at the minute, along with M13.
Needle is a stack of 35x 20 second exposures. I had gain at 500 for this and it was very noisy and I had to process it to within an inch of it’s life to get something out of it.
M13 is a stack of 80x 7 second exposures- the same gain, but the shorter exposure/more subs seemed to help, and in comparison it fell out of the camera and processed itself (OK- I exaggerate).
Started imaging at 11:15 and done and dusted and in bed an hour later! Hopefully will get another go at this on a darker night and with more time to play…
Not a fan of either , but very surprised to get startling crystal views. Took over x200, some cracking details and fun to observe . This 35 year old Vixen 102 f10 punches above its weight as a classic achromatic.
So good that I put the phone over the eyepiece and took a few snaps. I have a digital cam holder somewhere. Seems strange that small eye relief eyepieces give results ,against bigger and longer eye relief ones, under ,
clear skies ! Nick.
Finally some time to process a little data and M3 globular cluster looks good. Not as impressive as M13 but still a superb target!
Finding time is my biggest enemy these days 🙂
