Description

This small Sharpless object sits high in the northern fall sky north of SH2-171 which is a common object imaged and south of Abell 85, a supernova remnant. The object responds to mostly red filters so a red luminance can be easily used on this one to produce a nice RRGB. It also does very well with a hydrogen-alpha filter and exposing the camera for a very long time begins to pick up a fainter area around it. It also responds very nice with the sulfur II and oxygen III filters so this one makes for a great narrowband color image..

This is a bit of a bull's eye with the O-III in the center then the HA (a lot) finally the S-II towards the outside.
