What palette did you use? Where and how much narrowband signal did you add?
I'm also currently imaging this planetary nebula, but I haven't collected as much data yet.

From the photo comment, it's not very clear which palette is used in the bicolor.

Information on the number and duration of subframes in the image annotation. Bicolor—Ha to red, O3 to green and O3 to blue in a 1:1:1 ratio. Blended with colored stars in StarTools using the star mask method in the Layers module. The object is admittedly a bit small for a 1-meter focal length, but some details are present.

I think the TAL-250 could capture more interesting shots. Good luck in our challenging but very fascinating hobby.
