Telescope

 250mm (10inch) F4.8 Newtonian Reflector. Focal length 1200mm.
Televue Paracor coma corrector. Its 1.15x magnification changes the focal ratio to F5.5 (focal length of 1380mm).
Baader MPCC coma corrector (since Feb 2007) Allows imaging at F4.8, 1200mm. Initial impressions are that this coma corrector is better than the Televue Paracor for CCD work. However it does require a couple more cm of back focus.
Televue 4x powermate (used with the web cam) focal ration F19, focal length 4800mm
The Red Dot finder has turned out to be more convenient than a finder.
