ClusterFest - Multiple short integration images as part of my Messier project

[Stub Mandrel]

I don't expect any of these images to win an award, basically I spent two nights trying to get as many globulars and open clusters as possible, given that those low down don't make much of an appearance here and I suffer from nearby LP low in the south west.

One or two were replacements for disappointing earlier images, most were new targets for me. Unless otherwise explained , these are roughly 10 one-minute subs for each of RGB, no luminance. The ones where there was a shortage of subs are most interesting. all cropped down to 1200x900 and jpg to save space.

M13, I wanted a half decent image to replace my 'nearly' ones, so 2.5 minute subs. The red wasn't excellent because the sky could have been darker, so I took extra subs to compensate. Something like 20 red, of which 6 or 7 discarded, 10 B & G. I think some more work on this would give a better looking result, it doesn't 'sparkle':

 
M53, another one I wanted a better version of, but shorter exposures than M13:

Then down to M80 - I got two red subs before it went behind a roof, shows how much more even a small number of subs (as above) brings:

M107 - you can see there are plenty of stars in the core that would show better with longer exposures or less LP:

M10 and M12; interesting to compare the colours. Does M12 really have more blue stars?

M9, quite a small one:

M23 - it's so hard to make open clusters look like anything other than a random pattern of dots...

M18 - the last one, cloud came in and hid it before I could do more than 1 or 2 blue subs, and despite some playing I couldn't get the blue stars to show decent colour:

Conclusion... a useful set of 'record' shots but the M13 shows the benefit of more integration time. It has the potential to be a much nicer image so I'll go back to the data.
