[Jethro777 (Jethro)]

Well,

I applied a lot of advice here (Thank you very much!), and I had some issues with star trailing (I got a bit greedy and went for a higher exposure than I could afford, lol).
I also got some tips on post auto-tiff (DSS) photoshop adjustment - just curves and levels, and black/white point adjustment that was very helpful.

It's made such a difference! I know it sounds silly, but I had no idea there were so many stars behind the stars. So, so satisfying.

I'm told the lens I am using (Minolta 100mm f/2.8) is unusually suited for astrophotography as it is a particular high grade macro lens with a flatter field than usual and is sharp.

Now I REALLY want to get that barn door tracker working.

Camera Settings:

Sony SLT A77 Mirrorless
Minolta 100mm f/2.8
f.2.8 wide open
3.2 second exposure time
ISO 2000

Dark, Bias and Light frames used. Did not use any Flat as I can't make them properly. (What suggestions do you have for making them?)
