I agree the QE is good for single shot colour chips, and is good for the money, but compared to the ST7 it's not good, hence my comment - I realise "I can't have my cake and eat it", but wouldn't it be nice if a cost effective camera like this one had the 80% - 90% QE of the ST cameras?
I suppose the downside is noise. As you say, the noise is very good in those sony chips, as compared to the ST cameras where dark frames are a requirement.
Going from 85% down to 60% I'd have to increase my exposure times by 1.4x ? ... so 20mins would become 30mins, 40 become 56 ... hmm.. I suppose once it's guiding it's guiding, but it does mean less frames in the same time...
You do put it in perspective. There are many chips lower than 60%.
Did you buy the camera direct from the US ?
