Thanks very much Greg, I really enjoyed your recent widefield version (you had the shockwave nicely!).

I've only attempted HaRGB a few times and haven't been conspicuously successful, so I don't have any advice to offer on that topic...

Thanks Rick ... hopefully not 70hrs! I think you're right I'm pushing it uphill a bit! My NB subs were only 10 minutes and while its a 12" f4, it is a dslr and uncooled.
Also I generally save from DSS to tiff format, RegiStar only likes 16bit tiff (but can handle 32bit FITS) so I might think about a restack...
Actually a recapture, might try and take longer nb subs now that I've got a bit of a handle on the tilt issue the existing Ha data is poor and probably not adding much at all

Conditions are looking alright tonight, I might try and nab a few hrs of OIII.
