Still tweaking the RC telescope (collimation) and running trials on the Moon to check the resolution of my setup ready for imaging the Sun next spring.
Here's the waning gibbous moon from last night in the freezing cold at 1:30 am and a closer view with a 2.5 x Powermate. Both imaged with my acA1920-155um (IM174) camera and processed using AS!3 and IMPPG.
Late in the night and freezing, I remembered why I chose solar astronomy

My first solar images with the RC scope were a bit blurred and it turned out that the thing was out of collimation (no real surprise) but at the time I didn't have any means of checking. I've now invested in a Takahashi collimating scope and soon I'll have a Howie Glatter laser to project concentric rings, so I'll have no excuses for not being in collimation in the future.
Thanks for looking.
Stu.

Re: Lunar reflected light
Stu:
Very good Moon shots in the cold, well I also know now why I do more solar work than when I was younger...,cold!
You will love thew Takahashi collimator scope as also Howie´s lasers, unfortunately he passed away some month ago, hope that his wife keeps up with Howies ideas and good craftmanship.
I also have used the very good Hotech (David Ho) 3 laser collimating system, it works wonders with catadioptric scopes.
Good luck with your collimation and have a nice weekend,
Eric.

Re: Lunar reflected light
Many thanks for your comments, guys.
Eric, yes I'd heard about Howie too and for a while his laser collimators and holographic attachments were nowhere to be found. It seems that this has now changed and they are back on sale. There's a bit of a lead time but I can wait.
Thanks fir your input.

Re: Lunar reflected light
Wow! you are very brave, I thought about it for about 10 seconds and decided on my warm cosy bed
These are much improved on last time

Re: Lunar reflected light
These look good Stu. Be interested to see how you go on in the collimating department.

Re: Lunar reflected light
Greetings from Florida (conference not holiday, sadly). Beautiful blue skies, but no scope and under cover in the conference centre all day anyhow
Thanks for your comments, Alexandra/Mark. I did fight the temptation to stay on the warm, but I really wanted to try out the scope to see if there had been any improvement. I was so disappointed initially, but tweaking appears to have paid off.
