Same Flat Results Lacking Detail

Since this is the "Galaxy season" I have tried to get some good images using my Celestron Edge 800. But I am failing. This image has 476, 3 minute exposures - enough data to get a detailed image but as you can see.....flat and without detail. Yes, I realize it is 37,000,000 miles away.
I am using a ASI1600MM-C pro camera and can rule out the camera and filters as this combination does well on a Vixen ED81s refractor, 8 inch Newt, and my wide field Stellarvue and AT refractors.
I can add sharpening in PS using the High Pass option but the artifacts can't justify it. I have an OK understanding of what PixInsight can do...and that gets me by on widefield and most Newt shots.....but the Edge has beaten me down.
When I get some time I am going to try to google some help on "how to get sharp images using the Edge" and see what I can find. I have even thought about buying an QHY183 camera.....as it has the best resolution (ie detail) for my budget.
Any ideas or PI suggestions are welcomed. I will gladly share the Light Frames, calibrated and registered and ready for post processing if anyone wants to try their hand at it.
When all is said and done....I might just use the edge for planetary and lunar.

Ed, Probably can’t help, but I will give it a try.
I’ve played a little with PI, sometimes it works well for me, others times not so well. I go back to preprocessing in Nebulosity and post-process in PS and get better results. I can’t explain why I fail on some images in PI and why it does fine doing it my old way, but it happens.
Is that scope f10? Have you shot that slow before and if maybe that’s the problem?????

It is F/10....and I have shot at that aperture before. My son gave me my first two telescopes (Vixens) but my first purchase was the Celestron 8 inch SE F/10 but those images were equally flat and lacking detail. I have been looking at Celestron SCT's (all sizes 9.25 and up) images on Astrobin and can see that others are having the same results. I guess I will just need to figure out a better processing path to get the results I had hoped to get.
Obviously using the same workflow that I have been using with my widefield images does not work on the Edge......and when i do some masking and sharpening in PS - artifacts.
Back to the drawing board but .....
The fun is in the trying!
