About this object
On the border of Cepheus and Cassiopeia, lie several interesting deep sky objects. The Bubble Nebula (NGC7635) is probably the most famous located center right. At image center is the HII region, Sharpless 2-159. Below and to the left is the emission nebula NGC 7538. Just above and to the left of the Bubble nebula is Herbig-Haro object HH170. Lots of dust also permeate this area. Up in the upper left is the open star cluster NGC 7510 shining at Magnitude 7.9. There is a whole lot going on here and I included an annotated image outlining these objects.
This image was taken on the first night at the Eldorado Star Party in October of 2020. I didn't expose for too long like I normally do as this was sort of a test image to see what kind of depth and signal to noise I could get using the low noise/high gain setting on the ASI 6200 camera. Even in dark skies the luminance exposures were just 95sec and the RGB exposures 150sec. These short exposure times also didn't require any guiding. I was quite pleased to see that this gain setting worked very well for shooting through broadband filters.
