Just wanted to check in and say the continual stream of advice here is making my images better. This is a stack of 43 using Autostakkert with some slight curves in GIMP. I did the stacking and the curves remotely using my tiny phone so they ended up pretty dark, but I actually like it in this case!

Re: Getting better...Sunspot with 152mm PST Stage 1
And as always, comments for improvement welcomed. For instance, I still shot in color (not having good time with mono yet) and I did not do any sharpening or wavelets (Registax is flaky for me as many of my tools minimize and never come back to where I can view them in an expanded state).

That's pretty impressive. Persevere with mono would be my advice.

Re: Getting better...Sunspot with 152mm PST Stage 1
Jack,
My advice to use about 67% of the present scale. You will not loose the reasolution, but will win in Signal/Noise and can use shorter exposures, will gain in the FOV size. And, of course, no coloration till your post processing is finished.

Re: Getting better...Sunspot with 152mm PST Stage 1
Thank you, Val. Can you explain more about your suggestion to use 67 percent of the current scale? I am not sure what that means in execution. Is that telling the camera to capture a smaller region of interest? Or telling my stacker to use a region of interest?
Thanks,
Jack
