M15 LRGB

This is from last night's session. Messier 15. It is almost impossible to not blow out the core without doing HDR processing. It has the densest core of any of our galaxy's globular clusters, and is suspected of harbouring a black hole at the centre.

Nice job on it. Yea your right it is tough to get the core to just not be a white blob

Hi Kathy,

It's a beautiful image, thanks for sharing with us.

What I have noticed from several posted glob images, my own included, is that when trying to bring out the core, the core takes on an almost "peachey" hue. Not the color you would expect from a globular cluster. I have not yet found a way around this condition. Of course, it could just be my monitor not showing the "true" color. Hmmm.

Cheers,
JT

Well, there are supposed to be more red and yellow stars in a glob than in the galactic population. But I hear you about the colour: it's not quite right, IMO.

Well, its a dang nice image Kathy ! :-)
These little gems are so very photogenic.
Thank you.

Didn't want to post my image here, but here is a link to it so you can see nearly the same color exhibited by the core.

Looks great! Well done, Kathy!

Nice little tidbit of explanation there about the densest core with possible BH. Had no idea...

I'll have to show a little more respect for M15 next time I wander over there.

Nice image!
