Hi guys,
A work in progress post.
This is a tight, full res crop from 3.5 hours of Ha shot just before the New Year. I did a quick process on it since it'll be a while before I get the colour data.
I used my 645 reducer this time - F5.5, 825mm @ 2.21 arcsec / pixel. The full frame is a 2.4 degree FOV but I'll only be posting that when it's finished. Seeing was good enough not to have any effect at this image scale.
Full res crop:
