NGC 6823 and Sharpless 86 Revisited – More Exposures

I was able to get out to Tierra del Sol on July 5th under much better conditions and acquire an additional 3.5 hours of hydrogen alpha data from this object.  The images below are the result of 6 hours of 270 second exposures [ 80 subexpusures ] from June 18th and July 5th.

The telescope that was used for the image was the Stellarvue SV70T and the dedicated f/4.8 reducer/flattener. The camera was a ZWO ASI1600MM-Cooled camera using a Baader 7nm 36mm hydrogen alpha filter. The camera gain was set to 200, the offset was 50, and the camera was cooled to -15 C.

The image below is a full frame wide field view of the area showing the Sharpless 86 emission nebula.  The open cluster NGC 6823 is centered in this view.  Click on the image to see a larger view.  Also, a full resolution view of this image can be found at this link.
