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 :lol:

Thanks for looking.

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.

Nicely captured Ray, quite a number of background galaxies when going surfing :) Good resolution and detail in the galaxy too!

[multiweb]

Very cool Ray. Superb colors and details as usual. Lots of interesting little background galaxies with some structure as well. :thumbsup:

Dots?...DOTS???:eyepop: where?...I don't see any dots :scared: :scared3:

Excellent image, lovely overall look very natural but highly detailed. If I can't see dots or worms then...:question:..you have clearly mastered the use of decon/wavelets application Ray :D 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 :)

Ok, here's another one of these: :prey2:

Mike
Who still wants a long FL CDK :P :lol:

Excellent image Ray! Wish I'd taken it.

Cheers

I'm a big fan of your images also Ray.

I really like this image as well. Beautiful stars too.

Greg.

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


thank you Colin.


Thank very much Marc. appreciated


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 :).


very generous - thanks Steve


Hi Greg - thanks very much.

Beautiful. A cracker. Top shelf.

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.

[RickS]

Great detail and colour, Ray! There aren't many images of this puppy around but even if there were I'm sure yours would still be one of the best.

Cheers,
Rick.

Nice one, Ray!

[Slawomir]

What a pleasant image to look at! Pure joy for the eyes!

10/10 from me, awesome work Ray :thumbsup:

[marc4darkskies]

A lovely crisp image Ray! Plenty of faint fuzzies to warrant a close up inspection too. Colours spot on as always!

Cheers, Marcus

Hi Ray,

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.

Peter

[astroron]

A very nice image Ray. :thumbsup:
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:thumbsup:

Ray,

You continually provide us first class images, from capture through to processing - well done.

Steve

[Shiraz]

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..


thanks very much Lee.


that's very generous Slawomir - thanks.


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 Steve - appreciated.

Hi Ray,
beautiful image -
that 10" f4 is really going well.

cheers

Hi Ray,

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?

Peter

[Shiraz]

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).

hope this is of some use.
regards Ray

[PRejto]

Many thanks, Ray! It does help. I think I "win" in having the worst gradient...even after DBE.

[LucasB]

Another cracking image Ray. Well done!:thumbsup:

[RB]

Absolutely beautiful shot Ray.
Well done.



Peter that looks like one of Ironbird's re-creations.

:lol:

[Shiraz]

yep you "win" ... crikey



thanks very much Lucas


thanks Andrew - appreciated
