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.
I loved as much as you’ll receive carried out right here. The sketch is attractive, your authored subject matter stylish. nonetheless, you command get got an edginess over that you wish be delivering the following. unwell unquestionably come more formerly again since exactly the same nearly a lot often inside case you shield this increase.
