Description

This is yet another image of my study of Cassiopeia (from Sept-Oct). This is a discovery project--pointing and shooting the camera just to see what I can 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, so most of the interesting DSO objects I see on Astrobin are only tiny blurs, lost in the large field of the RedCat. Still, I think it is a useful exercise in shooting targets, post-processing, and getting a feel for what's out there.

Beta Cas is a giant, variable F2III star that appears quite white. This particular shot is oriented with Caph at the south end of the frame. The result is that many interesting DSO to the south are not visible in this picture. This was an intentional choice on my part.

In the 'B' revision of this image, I changed my workflow rather drastically. The original image was created with a lot of stretching and, I think, too much post processing time. It is heavy-handed and crude in an attempt to 'see' all of the features which are too faint the RedCat. It's sloppy, messy and the stars are...well...unacceptable. The 'B' revision is a complete reworking of the data using a completely different methodology. It is harder to see DSO in the 'B' version, but it has the virtue of preserving star color and being closer to what the eye naturally sees. Please take a look at both versions; you decide which 'style' you like more. Both have their uses, I suppose.

I hope you get some benefit from the image(s) and the others in the series.
