Sh2-86 is a large emission nebula, in the constellation Vulpecula (Little Fox). The open cluster (NGC 6823) at the center of Sh2-86 formed approximately 2 million light-years (ly) away and contains very young, hot stars. It is about 50 ly across and is approximately 6,000 ly away from Earth.
Because of the large, dark, finger-like pillar of eroding gas and dust (bottom left) in Sh2-86, this nebula is sometimes called a mini-M16 (Eagle Nebula), which contains the Pillars of Creation.
I decided to try my small pixel (2.9 microns) ASI585MC with my 107PHQ at 0.81"/pix. I was pretty happy with the result and was able to pull some detail out of the image of Sh2-86 comparable to the image I acquired with an EdgeHD 8 last October, with only a slightly smaller FOV.

I was a bit groggy last night and selected the wrong version of Sh2-86, without the final noise reduction. I think it brings out some details a bit better without over-smoothing.

@terri Thanks, Terri. I'm really liking the tighter shots I can get with the little 585MC and a medium fL scope. Nice little camera...
