NGC7822

Post by OhNo »


The sky is still garbage with the smoke in the upper atmosphere but...... On the plus side I have discovered a few important issues with imagining under un-favorable environmental conditions. First lesson is the negative impact a Oiii Narrow Band filter has on the end result. Second is the fact that attaining a very good focus is next to impossible, Yet, I keep tinkering around.

Reading some of the comments on other peoples images keeps the ideas coming and worth exploring.... The image below is the result of such a experiment. I had gathered a minimal amount of data for this trial run. It is 14 180 second Ha images, 5 each of RGG at 180 seconds each. This is the maximum I can image on this target in one evening. From dark until the dome of my SkyShed Pod gets in the way of my guide scope. Guiding through the smoke is a lot tougher than even an average sky offers.

Data was acquired with StellarMate OS controlling a ASI183MM Pro in a SharpStar61 EDPH II on a old CGEM. A StarField 60 guide scope with a ASI120MM Mini does the guiding. I use the internal guide software that StellarMate (KStars, EKOS) has.

Majority of the processing was done in PixInSight.But this time I used a new workflow. I converted the Ha grayscale image to RGB and ran it throgh StarNet++ to eliminate the stars. A mask was used on this starless image and I used the Pix Curves transformation and Color saturation to taste to apply the color. The RGB data was combined in Pix LRGB combination and the result was tossed into StarNet++ to eliminate everything except the stars. Once that was done The Starless and star image were combined using Pixel Math.

I realize I should get more data, but experiments must go on even with less than ideal workin' material! :D A minor trip through Luminar AI gave be this result.

Comment and opinions welcome as always.
