Thanks for the interest, not a pretty image but I always wanted a go at this challenge.
Ken, the CMOS binning is different, the ZWO forum members had a complaint about average binning for the 290 but the technical guy would not add the bin for 16 bit saying there was no advantage. I was skeptical but after looking at the maths it seemed to be true and after testing I am very pleased with the noise and sensitivity. Can't wait for the planets.
