Great editing! Thanks for sharing!

Thank you too!

Thanks for posting this! I'm going to use this to hopefully streamline my process a bit.

You may be the Snickers winner. :)

Hope your trip was great. Glad to see you having fun imaging from a dark site.

Thanks for the video. I do have a question. During all this process when would you invert the image and run SCNR to correct the magenta stars? You didn't suggest that part but I've heard that could be done. My image is coming out great with this workflow, but the stars are magenta outside of the nebula. I'm not sure if I should use a mask here for getting the magenta stars to look normal.

[@real_astrotard]

Sometimes I do the invert scnr for magenta stars, sometimes not. In this case I did not since I didn't really see any magenta.

Great video. Thanks. How does the process change when you have images taken with each filter over multiple nights with flats for each night?

[@real_astrotard]

I only take new flats whenever the imaging train changes (e.g. rotating the camera, cleaning the lens, changing a filter). If the imaging train remains untouched I use the same flats over and over with success I think.

@@real_astrotard But if you did have multiple images in one narrowband, say from two different years, would you use pixel math to make the two images one?

[@real_astrotard]

@@toddnoseworthy1447 Over multiple years (with different calibration frames), I merge them to the point of registration. Then when they are all calibrated using their specific flats and registered to one, then I'll manually integrate the old and new. Usually the key here is using the FITS keyword WBPPWGHT in the integration tool in PI. Assuming I calibrated & registered with WBPP.
