This image was a test, wether or not the TSO 65/420 can be combined with the CCD47 reducer. The result is there is strong astigmatism almost everywhere but strong is relative. The astigmatism of a decent prime lens is not less. I was not sure if the image is worth adding color data. So I decided to do some artwork: I separated nebula and stars and created artificial R, G and B mixing a large amount of the nebula to red and less to green and blue. The original Ha was then used as luminance in an LRGB combination. Reminds me of the old times when originally black and white movies had been colorated manually.
C&C welcome!
