Which target is "usable" in Spring with narrowband filters in action? This is always a challenge at this time of the year. Sh2-290 offers a chance, even when you targeted this object already. So I checked my old image (
https://www.astrobin.com/lssbwk/D/?nc=&nce=), which I actually found pretty pleasing already, but it was taken with the old classic, ASI1600 😊. So I had to check if the 6200 would provide a better image, hence giving it some time. NOT a new Sharpless object in my list though!
After finalizing the processing work I had to compare, and I was not really very much pleased with the new result, I almost like the older version better, definitely not a huge difference.
One other part that made this image interesting was that I used the ASI071MC and my FRA400 for the RGB stars, since I had the setup due to the solar eclipse, and I could not resist seeing if that will be possible to integrate. Man, I cannot even remember anymore when I processed my last RGGB image, 2018 or so! I had to look up some YouTube videos about it, and some PI tutorials (finding the checkbox for RGGB integration in PI took me a while 😂😂).
The resulting stars were also not the best, so I did my usual trick to use the stars from the H and O channels, and "color" them with the RGB stars. Not perfect, and maybe this is what bothers me most in this image.
Live long and prosper!
