Jannis Posted February 7, 2021 Share Posted February 7, 2021 That's a stunning picture! Did you use RGB or narrowband? How much exposure did you capture to be able to pull out all the faint stuff that well? 1 Link to comment Share on other sites More sharing options...
SiriusDoggy Posted February 7, 2021 Author Share Posted February 7, 2021 Ah, sorry, forgot to leave the major details. 15x 60sec subs on each LRGB 40x 5min subs on Ha = 200minutes. 13x 5min subs on OIII. I was hoping to get 200 minutes of OIII data but it made it down to 20° altitude so I had to quit for the evening. I'm a bit of a faker when it comes to post processing. I don't have PixInsight so I use Astro Pixel Processor and PhotoshopCC. I processed the LRGB image to get the star colors and then I processed the narrowband in HOO palette. Into PS and I selected stars only on the LRGB image and copied them on top of the stars in the narrowband image. Baader filters, LRGB, Ha 7nm, OIII 7.5nm.

SiriusDoggy Posted February 8, 2021 Author Share Posted February 8, 2021 I re-processed the same data to work on the star colors. There were too many green stars in my first version. Hopefully this is improved. 2 Link to comment Share on other sites More sharing options...
