I mean no disrespect, Colin, but running the 1600 at less than unity gain doesn't make a lot of sense to me...you can't capture additional dynamic range, whereas with your 694 you get full 16-bit (well, depending on the gain setting). The only thing I can conceive as an advantage is not blowing out any bright stars in the FOV. But that's just me, I'm keen to be educated
If anyone wants to donate their 694 (or 674, I'm not fussy
) to a good home, PM me and I'll send you my address
