Hi all,

Struggling a bit with the processing on this one. Not much colour coming out of the galaxy and lots of noise. Probably just need more exposures but have non-trivial quantity already.

I am happy with how much of the further extends of the galaxy I've retained after putting some RGB on it.

First tried LRGB combine in PI but that killed a lot of fainter detail, obviously yet to work out the ay PI does LRGB. Then applied Luminance to RGB in PS and that worked much better, at least not killing the detail.

Register, integration and DBE in PI. The rest in PS. Star shrink, noise, sharpening, etc.

Regards,
Roger.

While it has a bright core region, this is a pretty faint galaxy Roger so it is a challenge to process, I love the faint straggly spiral arms on this one, I did a shot of it a couple of year ago and it needed quite a bit of exposure even with 12" and at F3.8 in order to render the arms properly.

There is much to like about that image Roger.

It strikes me as a bit like a cross between 6744 and 1566.
