Very nice, the Southern Skies are beautiful, I miss those DSO's up here in the NH..

Great shot, not experienced enough to provide any feedback, did you do darks and flats?

Thanks guys

"baggywrinkle" - yes I'm quite lucky; I live in the near dark, 100kms from Sydney and up around 700m in the Blue Mountains.

Paddy - I captured what I thought was a "dark" but I noticed that subtracting it from the set of "lights" produced significant artefacts.  When I looked at the "dark" it had some very low level signal in the first few bits.  I think I must have had light leakage somewhere - I had the front cover in place on the scope so perhaps I have a problem at the back.  Anyway, no, the image does not include any "darks". 

Cheers
