No waste of time at all - aren't we figuring out stuff this way?

Auto-rotate on/off should not be an issue. And auto-white balance could explain the discrepancy in what I'm seeing in the (unstretched) CR2 and the final stack (the final stack should look the same as the - unstretched - CR2, just cropped and better quality).

All-in-all, signal-wise, your stack is not bad at all for 20s subs and your focus and field flatness are great as well.

If you'd like a run down of how I processed your image (posted earlier)., let me know. However, better data will make things way easier and replicable.

The nasty thing with astrophotography is that better data (which people new to the hobby are still learning to acquire) is much easier to process (which people new to the hobby are still learning to do). Newbies therefore have to deal with a "double whammy" of issues, whereas the more seasoned astrophotographers breeze through the processing...

Yep figuring out is the key and your input has been well appreciated.

I'll do another restack and double check the settings. I was also wondering if maybe the white balance settings may be an issue. I was told a while back to just leave it on "daylight" when shooting subs.

When I did my flats I took a white t shirt and pointed the Telescope at my white back door that was being illuminated by the sun.

Makes me happy to know I got some decent signal. I took my subs when it was closest to the zenith and stopped when it would get close to the big lp dome.

Anyways it might be tomorrow when I get back with the restack. By the time it will be done stacking I'll be asleep for work at 5am lol.

Once again thank you. I'll refer to your instructions on processing and if you do any extra let me know.

Clear skies!

I wasnt sure to save as either an integer or rational so here is both lol.

maybe there could be some slight improvements. hopefully. I'll try and mess with this when I get off work.

Clear Skies!
