Good little camera. Haven't had much call to be using mine the last few months (rain!!!), but before that I used it when I could. Only two gripes with it....it should be cooled (it's an uncooled camera) and it sometimes shows a ring effect around bright stars (like it's sharpening them up). The ring effect can be processed out, the other needs attending to with a bit of imagination. jjjnettie (Jeanette) has produced some quite good images with her camera of late. You can also go and see Steve Quirk's piccies at his website....
Frog Rock Observatory and pickup some good imaging tips too. His book (along with Steve Massey), "An Atlas of the Southern Night Sky" has most of the pics in the book taken with the GStar.
If you haven't purchased one, yet, Steve (Massey), who owns
MyAstroShop, should have some of the new wireless version of the GStar in stock. If you have an earlier version, it can be retrofitted. But you'll have to wait for the kit as he's out of stock at present.
