Description

As I did a bit over a year with the achro on the Horse Head I needed to try this approach on a wider field. Used instead of OIII data (which are barely present in this area of the sky) the Hß data and applied it to the blue channel. For this maybe most famous target of the sky something different is always a good thing 😊. I wanted to work a bit longer on this image this week, but when my wife came into my office and saw it (in full size across 2 monitors) and said "I want this one on the family room wall" I knew that I had to stop processing 😊, this honor was not given out ever so far 😊😊. Now I do not know what to do on today's holiday 😂.
Standard SHO processing was applied. Maybe most interesting extra processing step was a DBE on the already stretched and combined image, which for some reason I thought was maybe not a bad idea, and it turned out to make the image more special (IMHO of course).

Title: Corrected Stars

Description: Although I love this image as it was, I was unhappy about the stars at the edges since the reducer caused quite some distortion, maybe my back focus was not perfect either. And when Thilo just recently commented on this image I remembered that I took another image of the area with the ASKAR 400 (https://www.astrobin.com/7wgj2l/), and yes, just "steal" the stars from this image and recombine, with a little BXT on top. Not perfect but the "bad stars" are gone 😊.
