I've noticed that in autodev, when I click on Shadow linearity, no explanation dialog box pops up.
Else, I'm lovin' it!

I too have learned to spend more time at the wipe/autodev/mask/re-wipe/re-autodev/remask/re-wipe stage and it does pay off. And like other points made above, I found better results by EXCLUDING flats, and letting ST take care of the vignetting. Living with repairing dust.... But that is not a good l...

or "User/Usage Notes". I know this seems really picky/low priority/semi-pointless.... but it took me more than a week to find an answer to "how do I select all the galaxies [Markarian's Chain] at once?" It was right there in the User Notes for masking. There was no link/reference to this valued info...

So I tried a set at ISO 800 on T2 PanSTARRS, not Y4. Needed Siril to find stars because DSS got zero (too small and faint I guess). I can't say the result is markedly better , but the conditions (moonlight!) and total exposure times were worse, so that implies the result is better. Due to inbound cl...

Good timing mentioning Siril.... my latest shots from Thursday night were done at ISO 800 as recommended, and DSS could not find any stars. Siril managed and built me something I could ingest into StarTools. Doubt the settings in Siril are as "pure" as preferred, but ya gotta walk before ya run. So ...

Thanks for the recommendation of SIril.
Clear skies!

How about this?! Oodles better. Apart from using a very small RoI around the comet, I found the real key was to use gamma to push the low end darker. I think I used green cap a bit too much, because many of my stars have a small glacial lake blue core, and they somehow bloated a bit, but that's all ...

I will try your suggestions on the ROI tomorrow (run out of personal discretionary time for today). Regarding using a lower ISO, I appear to be painted into a corner. At 6400, here is the histogram for 60s: Histogram_6400_60s.jpg My earlier teaching said to push the ISO to the spot required to pull ...

Thanks for having a look.

There are 5 lights, and the "predigested" dark,flat,bias. If you need a handful of the latter in Canon 60Da CR2 form, let me know and I will add them.
Much appreciated,

Out of (stubborn) curiosity I went through permutations and combinations to return to something workable, I found the following: ONLY "the Set black point to 0" checked, while NEITHER boxes under white balance checked. AND in ST I load with the "Linear" option, NOT the "Linear, from OSC/DSLR..." but...
