Hi
Got another couple of clear nights and the software was finally back working after a Win10 debacle. Was very pleased to see some of the outer extensions that are clearly displayed in a Galex image, but very faint in visible.
For Mike, some of those magenta dots really are dots - even in Hubble images
The full res looks good ray. Nice colour overall, but maybe the galaxy looks just slightly magenta. The detail looks really good though and there are lots of different category galaxies in the field too. I think more data would bring out the dust lanes more in the galaxy arms and help reduce the ever so slight noise in the back ground. Your image has prompted me to place it on my ever growing list of targets to image with the RC. Well done.
Excellent image, lovely overall look very natural but highly detailed. If I can't see dots or worms then.....you have clearly mastered the use of decon/wavelets application Ray This image clearly shows that a $70K RC/CDK or any large long focal length scope for that matter really, or 30+hr exposures, are just simply not needed to produce World Class galaxy images

thanks very much Paul - have posted an less magenta version.

thank you Colin.

Thank very much Marc. appreciated

Ok, here's another one of these:

Who still wants a long FL CDK
Thanks very much Mike - phew, no dots!!. A big scope sure would be better, but thankfully it is not totally essential in Australian seeing - mind you, better seeing would be nice as well .

I really like this image as well. Beautiful stars too.
The spiral arms show large and convincing but super-faint extensions. The pattern in the spiral arms is also very interesting - like two layers of cloud moving in different directions.
Beautifully handled colour saturation and background too.
Really nice image in all ways! Do I assume (or have forgotten??) that you image from a fairly dark site? May I ask what your integration and sub frame times were? I'm starting to "loathe" my imaging location! I spend 90% of my time trying to restore data from the horrors of LP.... Anyway, your usual great work on a very pretty subject.
A very nice image Ray.
I had not observed this galaxy before,your image prompted
me to observe it tonight with my 16" and a 6mm radian.
It has a very bright center which seems off set.
Takes magnification well.
Foreground stars to 13.6 mag seen.
Thanks Ray.
Cheers

thanks very much M & T. You are right, the patterns do look like cloud layers - amazing that similar physics seems to apply to both stars and molecules.

thanks Rick - I couldn't find many other images either, not sure why..

10/10 from me, awesome work Ray
that's very generous Slawomir - thanks.

Cheers, Marcus
thanks very much Marcus. I love it that modern imaging gear can pick up the faint background fuzzies - pity we cannot get more resolution on some of them.

thanks Peter. My site is in the middle of a small country town and I have two streetlights illuminating my obs and sodium site lights at a nearby dolomite crushing plant and grain loading terminal. The sky is not really dark unless the atmosphere is very clear and under the best conditions it can get down to about one mag brighter than full dark (estimated). I don't bother trying to image below ~50 degrees above the horizon, to keep out of the worst LP.
I don't have my imaging computer with me and will post details when I get back to it - from memory, about 70 lum at 5 minutes 1x1 and maybe 2.5 hours each of the colours at 2x2 binning with 180 sec G and R subs and 300 sec B.

thanks for that Ron. I haven't looked through a scope for a while - maybe I should.

Thanks very much for your reply. Since I'm using the same camera for RGB I'd be extremely curious to see a stretched version of your initial RGB combine if you might be willing to show it to me. As I said earlier I think I spend a huge amount of time trying to deal with a terrible grainy gradient. Even when I tame it I'm left with an ugly background that has blotchy colour. So, the question that I'm trying to answer is whether my data is much worse than yours, or whether (more likely!) your processing is just superior?
Hi Ray,
beautiful image -
that 10" f4 is really going well.
cheers
Allan
thanks Allan - not all plain sailing, but the scope has been pretty reliable

Hi Peter. FWIW, the attached shows initial RGB stretch (left) and then after background neutralisation (right). full scale centres of the images are shown at the top. Stretching is via the STF function in pixinsight and more saturation would be required - however the degree of light pollution and gradients can be seen (these images have been flat calibrated and are 2x2 binned).
Good resolution and detail in the galaxy too!
where?...I don't see any dots 
..you have clearly mastered the use of decon/wavelets application Ray
