Thanks Marc! I guess you mean slightly white clipped? Looking at the luminance stretching, the histogram shows a tiny spike at the extreme right even before any stretching. This is a little taller after some basic stretching, so I don't see any way to avoid it? It was an exceptionally steady night when I took the luminance, so perhaps the stars are showing sharper edges around the saturated cores where they would usually be a little softer?
Yes - white clipped. I guess your scope optics are so sharp all the light from the stars is focused to a point and they saturate very quickly.
Thanks for all the comments and feedback Lewis, David, Mike, Rick, Marc and Rob! I have reprocessed this mainly to fix the harshness of the globular and to soften some of the brighter star cores. Funnily enough, I had forgotten that I had originally taken 6 x 5 minute luminance subs with the globular in mind, so I have now processed this data and layered it into the luminance which has improved its appearance within the image. I also used it to tighten up a couple of the overexposed stars in the nebula as well.
In terms of the reddish colour of some of the nebula, I have to agree with Mike here as the data indicates that this is a true indication of the colour present; I would have had to suppress the red hue which would then mean I am losing detail. I think that because I have stretched extra detail out of the fainter portions of the nebulae it thus becomes more prominent, as opposed to the usual trend to portray it as darker. It's interesting as the norm for most nebula processing is to stretch as much information out as possible
Yeah the cluster takes a whole new dimension now. It has some depth and great colours. When making a pretty picture you stretch what you want to show and mask other areas then composite. You don't have to do a global apply.
Just beautiful.
I think my fav part if the wispy blues, particularly those towards the top of the pic. They really do look like hot blue starlight is being reflected off each individual wisp.
Even though I KNOW that's what's going on, this rendition makes you really FEEL it.

Yes thanks Marc; quite right and in fact I had collected those 6 frames specifically for the globular but as it had been about 6 months since collecting the luminance data I had forgotten about them

Thanks Rob, much appreciate the comments; glad that you like it so much!

Thanks John; the feedback from the forum was very helpful in fine tuning the latest version.
Wow, that is superb David! Really worth the wait for the colour data. I thoroughly enjoyed looking at this image at full resolution, there is so much to see.
Evidently a well collimated Newtonian produce spectacular images and is the ultimate imaging scope IMHO. Thanks for sharing this.

Thanks Rolf; yes I've always been a big fan of the simple Newtonian. There may be one or two others on the forum with a similar bent (Mike / Bratislav) ...
I also missed this one David, one of the most beautiful images of the area I have ever seen. Details are incredible, seeing, telescope and ability all contributed in equal form to this amazing image, my compliments!

Thanks Marco, a great compliment much appreciated!
I missed this one too David. It would have to be one of the best images I've ever seen of this region.
Cheers
Steve
Thanks Steve.

Thanks Lewis; actually I usually have a few goes at processing these images before I'm happy, so a bit of trial and error ... Some thanks too for tips along the journey by all esp. Marcus (marc4darkskies) and Marc (multiweb).
