You think? well I guess that's a compliment? Yeh go for it it is a beautiful nebula, I recon 600mm FL (or a two frame mozaic at 1200mm) and a few hours on this would churn out a pretty nice image

Glad you had a go Craig, I think the dark skies really do help here as does having a reasonably sensitive mono CCD, and remember, although rather short for LRGB imaging I still did 4hrs worth of exposure.

very nice image. Pleasing neutral sky background with a very natural blue colouring in the nebula with the faintest hint of pinks (probably from very faint Ha emissions).
Thanks master Scotty

Actually bad seeing doesnt seem to have caused much problem as the faint stars are still pretty small, barely a pixel across. Perhaps it might bloat the brighter stars but if it has its ceriainly not by much. A refracter on a stable mount will be better suited to iffy seeing than a big reflector anyway. I reckon transparency is the thing to get the best from the Witch head neb. and I imagine thats always quite good that far from populated areas.
Man, if you had been there you would have thought me completely mad for imaging ..err? you probably already do but for other reasons
