Crescent, first attempt at bicolour

[Horwig]

This was taken over three nights at the end of September, very much a first, first bicolour, and first time imaging at this resolution, 0.44 arc seconds a pixel.

4 hours of Ha, 5 hours of O3 all in 30 minute subs

I acquired 18 hours data in total, but so much of it was pants seeing, I didn't think I'd get anything out of it.

Kit:

40cm f3.6 Newt with a QSI 6120 camera, Astrodon filters.

This is a 50% resolution copy

Excellent work, your guiding must have been spot on.

Thanks, guiding was good, it was another first, first run with a Gurley encoder on RA of my Sitech controlled mount, guiding was about 0.5" RMS according to PHD, so much better and smoother that anything without the encoder.
