Bubble Nebula.
NGC 7635.
Sharpless 162.
Caldwell 11.
An emission nebula about 10,000 light years away.
There are 2 other targets in this image. Just above the Bubble Nebula is M52. The set of star clusters. Then to the bottom right of the Bubble Nebula is NGC 7538. I actually did not realize we imaged the Bubble Nebula until I moved files over from the AsiAir Plus to the PC. This is a first time targeting this nebula. It’s not a target that is usually not in view from my backyard.
Well, I guess it was a small window on this night. I took 65 light images but I was only able to use 35 of them to stack. Over half were out of view (tree, house roof, etc.). So, with 35 light images at 3 minute exposure it was decent amount to work with. In the post-processing I was still able to get some good detail of this small target. The same with even the smaller target, NGC 7538.
I am mostly happy about being able to image a new target. With my limited range from my backyard I will need to start traveling for new targets. Or get a new house. So, a good find from Myles on this one! I might not have tried for this target myself.
