2nd DSO - M13... any processing suggestions?

[Notty]

These were taken and stacked a couple of weeks ago, I can't even remember how many subs, but I put them into PS and tweaked the levels and curves a tiny bit, but apart from that I'm not really sure what else to do with it (apart from sort out a method for flats as I have a giant dust bunny).   Does anyone have any suggestions?  What else can you so with essentially a b&w starfield?  I've attached the original and also a cropped one as it was a bit small in the FOV of my ED80.

There should be some colour in there some where.

I'm assuming they were quite short exposures as not many stars showing.

Here is one of my very first of M13, I know they were 600sec subs with my ED80 and Canon 60Da.

It is fairly small in an ED80 and mine is cropped out.

Stacking in DSS? Did you bump the saturation?
