Could have been OK last night... maybe, but I got preoccupied elsewhere.
Took me what seemed HOURS to get the Starshoot to focus - I had to use a GSO extension piece, which I was not too happy about. In the end, got it going with fairly good focus - will do it better on a star MAYBE tonight, if the high level fluff disappears again.
Doing a dark test and a full bright test, seems there is one hot pixel permanently on my chip, and a piece of crud on the INSIDE of the glass platten (I can see it) that would appear to have shaken onto there in transit (TNT took 2 bloody days to get it here from Sydney, even though overnight was paid. They claimed some line issue) that DOES show in photos. Don't know what to do about that (Bintel said it was the last they had in stock).
Test images look O.....K..... (that was a drawn out OK). Not getting that warm and fuzzy feeling, more the sinking feeling - I guess you get what you pay for, but I was expecting better colour rendition (seems OVER green everywhere).
Not sure how long supposed to let it run to cool properly. A metric sheet ton of noise when the camera is warm - unbelieveable amount in fact. When the cooling has been on about 5 minutes, the noise is severly reduced, so that is a good thing. I just hope all the stacking rids me of that one bloody hot pixel!!!
May yet end up being a bloody expensive cooled guider

Back to DSLR, probably, even if NOT cooled! Maybe shoulda bought the cooler box and lived with the bulk
