Thanks Doug - I'll be sure to try some longer subs however as this was the first time I used the camera I was reluctant to blow a whole night and find I captured nothing. I've also been working on improving my guiding so was unsure how long I could achieve without drift. I seem to be ok at 5 minutes so might try 10 next time. I notice the histogram is peaking at 65,000 at 5 minutes however there seems to be some headroom at the black end - I assume this means I need to reduce the offset. I was shooting with gain=1 and offset=110.
Marc - thanks for the link. I ended up using one of the PS functions and this seemed to work pretty well. Do you follow the colour/lum split workflow as recommended on that website?
Cheers Troy. I'm quite impressed with this camera - easy to use and pretty nice image for a burbs shot. I would like to get one but am wondering how it would go when the temperature gets lower (eg at Astrofest) with no control over the cooling?
