IC 1311 Open Cluster
Above is a crop of the full image below. IC 1311 is the open cluster of stars, above right of center, in the upper image.
IC 1311 and surrounding area of Ha & SII gasses
IC 1311 is an open star cluster that lies approximately 4,000 light years away in the constellation of Cygnus. It is located a few degrees away from Sadr (Gamma Cygni).
I originally had planned for an SHO image (as per the previous one), but even after 6 hours of subs there was little or no OIII evident in the area. I decided then to do a bi-colour with the Ha & SII data (HSS = RGB) and then imported star colour from the RGB data into the narrow band image. The star colour is more evident when one zooms in on the hi-res image....the small star sizes remain as captured via the NB filters.
