Louie (who post on here) did some great photoshop tutorials on youtube that may give you a help - at least to learn where things are in photoshop. https://www.youtube.com/channel/UCJ5...Ge66vsuSaXb-0A
Keep at it and keep in mind that it's all a learning curve that never stops, and that learning is half the fun.  |
Thanks Cam great link lots of stuff that i wanted to know how to do in ps there for me to learn.

It's a terrific autoguiding and planetary camera, and, as you've seen, as servicable DSO imager for shorter exposures. I've never tried DSOs with mine, but might give it a go on narrow field, on a cold night!

Yeah shame the chip is so small makes it diffucult to pick suitable targets for imaging.
Cooling can be a problem the other night the sensor was reading 24c and i was getting lots of noise.
Using auto dark subtract helped a little but as the night progressed it fell to around 15c i could really tell the difference at that point.
Maybe one day ill work out how to DYO cool mod the cam i think it would be worth it.
