This image been sitting around for a couple months now. It is the last of five images of the brightest stars of Cassiopeia shot during September and October. This was a discovery project to see what I would be able reveal around each of the five brightest stars in the constellation. The RedCat + Canon combo I shoot with has a field of approximately 5˚x3˚ degrees. This means that most of the Cassiopeian objects I see on Astrobin by other photographers are only tiny blurs, lost in a large field. Still, I think it is a useful exercise in shooting targets, star control, post-processing, and getting a feel for what's out there...
Epsilon Cas, also known as Segin, is a main sequence B3V star, and is quite blue in appearance. There is a lot of dust and nebulosity in the region, but nothing particularly notable for a wide field shot. What is noteworthy, however, is the large number of open clusters in the vicinity. As I looked at this data, many of these were somewhat obscured by dust and swallowed by camera noise. In the end I opted to eliminate the low-level dust and nebulosity in an attempt to create the highest quality star field. There are many clusters in the area, but none of them particularly large or impressive at this resolution.
Still, the goal of this series is to explore the region, and not produce spectacular images. Mission accomplished! I hope you get some value from looking at the image.
