No success with Regim stacking. I find it selects images out and your left with 30% of the loaded images to stack. I guess I'll just have work out the best settings.

EDIT: Spoke too soon - will post results - I used tiff files produced by the script I wrote for purpose instead of loading RAW files.

Median combine seems to be the best. Not Sigma combine as shown. The green cast is typical of some programs. I found Wipe handled it well if Median combined.

These are better settings when using tiff files. I found the files from the script worked well, as did the master frames converted back to tiff.

Thanks Rowland!

I've managed to register images in regim, now I am trying to compare the output with what I get from DSS. Using your script produces good calibrated images! And since I will be taking some forced pause from DSO photography (my latitude is 51 N, so no more real dark nights for ~2 months!) I will have plenty of time for experimenting.

Nico. Thanks for testing all this. I will be very interested to hear about your comparisons.

EDIT: I cant believe I did that - Regim nested in Pixinsight posted on the StarTools forum - not intentional, I assure you.
