It works! Thanks Adam and Mike. PixInsight is an amazing product, but support and knowledge sharing from people like you (and a host of others) is really what sets it apart.

Ask and ye shall receive! That's very cool. Thanks to you and @MikeCranfield

Thanks for the info. I tried the "BatchFitsKeywordEdit" script, but indeed it makes copies of the files. I do like his script better because it allows you to put keyword entries at specific locations. Having the option to overwrite existing file…

On the subsequent attempt, I ended up using Photoshop to deal with the lens flare circles. I was unable to figure it out in PI

In a second attempt, I ran SXT immediately after DBE and SPCC. It did a much better job. I then processed the "Star" and "Starless" images separately and recombined them at the very end. Overall, it is better, but I'm not sure if tis is the righ…

UPDATE** It seems that the Folders above as well as the individual image file names are factored in the grouping? "NGC6992" is part of the image filename (i.e., "Light_NGC6992_300.0s_Bin1_20230711-230003_0001.fit") When I changed the subdirectories …

Interesting on the binning. I had been told (and read) that because of the long focal length and the size of the pixel I should bin to reduce oversampling. But I did not understand that is for mono cameras. I guess I just assumed it is for all ca…

Hi Adam, Here are the details of how I acquired the data and then processed it (it's been a few months since I took the pictures, so this is to the best of my memory). This was taken in urban skies, Bortle 7. Equipment:Celestron C11 (Non-EdgeHD), a…

Hi - Just to let you know all files have been uploaded: https://1drv.ms/f/s!Arcl9TtTrZIxhpIuW0lPQ2O06_08RA Thanks!-Matt

Hi, I would be very interested to see what you are able to accomplish with this data, and how you would go about processing it. I have processed it 5 times - starting from before I started with PixInsight (DSS and Photoshop), and several times as I …

Hi - Thanks for the excellent explanation! I think this played out exactly as you describe. I had 150 files, and after going through all of them, there were 19 that I would typically throw away because of star trails/poor guiding. However, I let …

Yep. That indeed did the trick. Sorry to send you on a wild goose chase. The original data already had the coordinate information in the FITS header. After integration, I did a "Copy Coordinates" script instead of re-computing the astrometry. Loo…

Sorry about that... XISF file is uploaded (file - save as... - XISF, left everything default) to the same OneDrive folder https://1drv.ms/f/s!Arcl9TtTrZIxh_Ze1g0-j0qQ4a_xlw Thanks again,-Matt

Some other details about the data that I didn't mention in my original post: 1) Given the focal length (2066mm) and the pixel size of the 2600, I used 2x2 binning during acquisition 2) I used an Optolong L-Pro light pollution filter during acquisti…

I saved as a TIF at the state it was in in the screenshot I shared, and uploaded to OneDrive: https://1drv.ms/f/s!Arcl9TtTrZIxh_Ze1g0-j0qQ4a_xlw The M101_Integration.tif file should be in that folder. Thank you for taking a look at this.

Here is a screenshot of the SPCC step. By registered data... did you mean something else? Also, I have not yet purchased the "Fundamentals" program - only FastTrak. I figured I'd make sure i'm not too far over my head...
