Hi Peter,
Yes, I might just do that rather than lose it in this thread. Good idea.
I havent used the MPCC on the QHY shots as it makes the coma worse as the spacing isnt right. I didnt even think it was going to be an issue when you asked me if I needed any spacers. D'oh!
I did use the MPCC on the DSLR though.
I used 20 mins per camera as a comparo, 4 x 5 min subs for the QHY8 and 10 x 2 mins @ISO 800 for the Canon.
Thanks for the bonus time! Its a pity the moon is full, but I will try some deeeeeeep shots hopefully on the weekend. I tend to get lost with the Nebulosity tutorials, so I might have another crack at those with just the QHY data after I post my please help process thread.
I think the thing thats killing me at the moment is the vignetting, so I will attempt some flats with the QHY so I dont have to process the hell out of the stacks to remove the gradients.
What is your suggestion on how to do flats (exposure time I spose...) with the T shirt method with the QHY?
I have posted a snapshot of the 20 min stacks below in JPG of the two cameras below so you can at least see what I mean. The Canon surprised me of how much it picked up considering its not modded.
These are both resized to 1024 x X and then saved as JPG at 85-90% to get under 200kb. Nothing else done to them since they were DSS stacked, so you can see how they came out of DSS.
Still feeling a bit embarrassed about what Doug said, hope he read and believed my response...

, it definitely wasnt intentional.
Thanks
Chris
