NGC 7822 The Cosmic Question Mark
NGC 7822 The Cosmic Question Mark
I had captured some good data on NGC 7822 a month ago and forgot to process it and it had pretty good detail. I ran a little bit of blending of RGB stars but mostly a lot of SHO in this image. I was pretty happy with how it turned out. The full question mark consist usually of the little rosette but my field of view was a little tight to capture it all.
