Hi everyone. This is the last in my series, clusters-suitable-for-full-moon. Promise! Anyway, I found this one by poking around in CDC around 20 minutes before moon rise so we've 10 frames in darkness and 10 moonlit frames at 120s each. It evened out well. IMHO, it's just as good if not better than the big M clusters in Auriga. It's alarmig the rate at which the moon sends the histogram toward the right...

Oh, and mainly orange stars. Old cluster perhaps?

Thanks for looking and clear (not necessarily moonless) skies:) All comments welcome.

Caroline's Rose, yes it's quite old at an estimated 1.6billion years and quite a few main sequence stars have used up their fuel and gone red gaint.

Very nicely done, the cluster is beautiful with the diffraction spikes.

Lovely image. I'm not a really a cluster fan (not enough, in your face, colours). This one I have had a change of heart. It's now o+n my list.

Hi. I understand what you mean. The cluster thing was very much just an experiment to find suitable targets for imaging around full moon. Now we're back to manejable moons, I'll almost certainly revert to the faint gassy stuff. I think pacman is next up...
