Hi all,

I managed to get some more data on this interesting galaxy. Details are:

Ha 18x10 min -20C bin 1x1
Lum: 50x10 min -20C bin 1x1
RGB 61x10 min -20C bin 2x2

Integration: 21.5 hours

Meade lx90 8"
QSI 683WGS
Optec Lepus 0.62x Reducer

More details and high(er) res on astrobin.

I took all your advice on board and processed a little differently to the first one. I backed off on the noise reductions, particularly for the lum channel. I also ran the subframe inspector script and weighted the images using a similar approach to here. Lastly I applied a little deconvolution. Other then that, my work flow was pretty similar to the first image.

This image has come out sharper and better than the first. I was happy to get some of the jet filament! It's still a little soft, but not sure if I can improve on that yet. My setup has some serious field curvature going on, as measured by ccd inspector.

Always after pointers in ways I can improve.

Cheers,
Aaron
