Ngc6744

At my last trip at my dark site I took some additional data of NGC6744.

I've added it to the data I had from about a year earlier. Keep in mind this is quite a dim galaxy really and it never gets that high in the sky.

It is a pretty faint sucker but you’re showing it nicely. Perhaps a little too much noise reduction but when you’re going faint and without heavy integration, cannot always be helped.

Nice one Greg!
This galaxy (like a lot of others) has a very low surface brightness - you've capture a lot of details and nice Ha regions.

Tony.

I agree with the comment about noise reduction Greg but other than that I think you've captured it very nicely. The colour is excellent.

Cheers

That's wonderful Greg. You've definitely gone deeper in the outermost tendrils of the spiral arms. Bravo!

Greg,

Great detail and colour and you pulled out some very faint stuff, Greg.

Cheers,
Rick.

Hi Greg,
that's an excellent image and
I wonder if the stars could have been processed to be a little softer?
The stars look a little bit over white and hardened.
It would have been very difficult to process give the high dynamic range.
I like the red Ha regions.

cheers
Allan

Thanks Allan. I have softened the stars a bit. Thanks for the suggestion.

Cheers Mike. I have done a bit of a rework this morning with fresh eyes and from the astute comments so far.

Thanks Colin.

I've done a rework this morning with fresh eyes and in line with these comment in mind. The new version has way more subtle noise reduction. Other ways to skin the cat.

Thanks Tony. Its a beautiful galaxy but a bit faint. Also imaging so close to the SCP seems to have extra challenges.

Thanks Steve. I accidentally ran a noise reduction routine a few times and it seemed like it failed at the time but apparently it worked each time! Fixed now.

Thanks David. Its amazing how much control we can gain using Photoshop. Is such a deep and powerful tool (PI is good too Rick!).

The rework is a nice improvement. Less large wavelet blotchiness and the stars are better

Thanks Pete. They seem to extend very very faintly into the area above the galaxy as well. I think most galaxies have a faint outer section which doesn't often come up in photos being too far away. At least I think so.

Greg.

I like this version Greg, nice warm colours, not to harsh... with detail out to the extended regions of the galaxy.
