Hello Group,
Apologies for the cross posting
The first of SBIG's ST4000's showed up in Oz just After Christmas and I was curious to see how the camera held up.

Hey, nothing special.... a 5 minute self guided exposure taken between cloud breaks from light polluted Sydney skies. ..(Dark subtracked, no flats...there are a few gradients that precluded stretching the data, AP155 @F5.2)
It does show this system has pretty good S/N performance and FOV similar to DSLR APS sized chips
Cheers
Peter
