It has "only" taken 4 months to get this image: weather, equipment problems, equipment misunderstandings and stupidity. Anyway, for what it's worth, here it is.
TEC140, 2X Astro Physics Barlow, ONAG (St-i), Moravian G2-8300, Hutec IDAS
1x1 image scale: .575 arcsec, or ca 1940 mm fl
Guiding has been problematic. I don't know if it is something about the IR signal I'm guiding on, or an issue with my mount, or my lack of experience. Probably all three! I couldn't afford to throw away much data so my not perfect guiding shows. But, some of the distortion may be the barlow/TEC combination.
This image is 4 hours in luminance, and about 2 hours each in RGB (some at 2x2, some at 1x1). I had to crop off the worst bits, and I've downsized the image to around 70%. There are plenty of flaws, but I guess I proved to myself that this could be done. I think I need a camera with better QE to take advantage of this focal length. Collecting luminance was OK, but colour was very difficult!
Thanks for looking, and comments always appreciated!
