I can't seem to get anything good out if it and I don't know if it's my image or my editing skills. I won't pass anyones edit off as my own I just want to see what can be done with the image. I shot this with a Sony A7III and a Zeis 85mm and used a light pollution filter. https://drive.google.com/file/d/1-WvmjkKZiZyCrufqTeOEKN2arWetloba/view?usp=sharingSorry if this does not belong here. Thanks!

Hello and welcome!
It appears that something went wrong with your flat frames (if you have used any) and/or the calibration procedure in Deep Sky Stacker (hot pixels have survived calibration, others went black). Also I am not sure if the appearance of the bright stars are due to the LP filter, or the image was shot under hazy skies. I think I can barely see the North America nebula at the bottom center of the image, so the bright stars should be Deneb and Sadr.
Could you provide some more info regarding software/equipment used, the calibration procedure and imaging conditions? More importantly, it would be very helpful for us if you could upload a single, unprocessed raw file from your camera.
I am really sorry that I won't try processing this image beyond the simple background modelling I've performed in PixInsight for inspection purposes. But if this is your first image ever, you shouldn't be discouraged!
Clear skies!

I just opened the file in Photoshop and there is NO red channel data in it, at all. So something in the stacking settings has killed the red channel. The Blue channel is also much stronger than the Green so perhaps you've altered the values in the "Raw/ FITS DPP Settings…." .

I agree that something went totally wrong during calibration.

I agree with all the above comments: something went wrong with the red channel. I would suggest trying without a light pollution filter.

Looking at it a different way … could it be that your flats were only applied to the red channel and maybe a tad too much on that?
