Cheers Trevor. I thought I was going pretty well with 5min subs and that 1hr integrated would be enough but have definately seen improved results with more subs using the DSI. What do you recommend?

The relevance of the finder/guider though? This is what we were discussing a while back, correct? If so, looks very good, you would have to be happy with that.

Gary, I was going on the PS info on the sky background where the RGB channels seemed pretty well balanced however as you say it's a subjective thing. The finder guider is as we discussed - I've picked up an 80mm Stellarvue with a helical focuser and with the DSI I can find a guide star in pretty much any field without adjusting the rings. I haven't checked the drift properly yet but I'm pretty happy with the stars in the middle of this image given it is a five minute sub. I know the paracorr will take care of the coma as I've used it with my DSLR.

Too much green and not enough blue perhaps. I used your image as an adjustment example for you, adjusting the individual colours with curves to tone out the green cast, which can be prevalant in QHY8 images as the chip is strong in the green. Green also could be light pollution.
Keep it up, the QHY8 is a wizz bang unit for its money!

That's the downside of these large format chips - you have to reduce the image size so much to get under the 200k limit to post or suffer JPEG artifacts if you keep the size and compress! The moon was >50% last night and I'm about 2km from Brisbane so the skyglow was pretty noticable however the QHY8 seems to cope with this a lot better than my 400D.
