I've recently published a 2-panel mosaic of the Eagle and Swan nebula, capture with my Esprit 100 and ASI 2600MC OSC. I think that for the most part, I like the result. The detail is nice, and 8h plus in each panel meant I could push the stretch without raising too much of the noise level. BXT, NXT and SXT suite also meant I could work well on the details and keep the intensive star field in check.
I think, however, that the image lacks a certain "oomph", that is hard to describe. But the image still doens't have that "awesomeness" that I was expecting it to have.
I think that one of the reasons is that is that it's too monotone - too much red and not a lot of other colors, specially blue/teal. I know this is a common issue in regular LRGB/OSC images, as Ha pretty much dominante over OIII and other signals. But I wanted some advice on how to stretch the image and get those nice Bluish/purple OIII+Ha signals specially in the center of the nebulae. I know it can be done, as I've seen other RGB images with this profile.
Also, I've recently been having issues with Pixinsight after color calibrating, SCNR and stretching (with GHS), I usually get a blue tint in the background which I can't really pinpoint where is coming from.
