Heart Nebula near Casseopeia in the night sky, 7500 light years away.
Is this a composite: No
4 hours imaged over 2 nights this weekend at Stub Stewart park, Oregon.
PP in Astropixel, Pixinsight, Capture one, Affinity Photo.
Mod D610, 420mm
Nice. Wish I had to patience to take and PP these kinds of images.
You have a good framing of the nebula and I like the soft glow of the larger stars in the bluish areas, but something in the processing steps is not playing well with the others. The transition on the left edge from bluish to red is especially noticeable, and the red nebulosity is very strange. I have a feeling the source files are good, but would be curious to see the result done entirely in PixInsight. It is meant to do all the processing with its various modules.
This is pretty, but just very far from realistic.
Much more realistic. The dark halos around the stars can be fixed by an adjustment of one of the steps in PI, but I don’t remember which one.
I think I’d define realistic according to the filters used – one look for using an HA filter, which just allows more of the red emission spectral lines through, and another set of looks for narrowband filter captures, in which each of the 3 filters can be assigned different colors. There are several standard palettes for that.
