M13 first attempt

[Apharov]

Here's my (almost) first light with SW 200PDS on HEQ5 with an unmodded Canon 70D. 20 x 45s @ ISO3200 unguided, 10 exposures thrown out. Stacked in DSS, output processed in Lightroom.

The diffraction patterns around the bright stars are a bit irregular. Does this indicate that the focus and/or collimation are somewhat off? Any other improvement ideas?-)

Minor additional info: I'm also using a Baader MPCC MkIII. The image here is a mild crop, but the whole image was coma free except for the very corners.

Very nice.  Looks like you might have NGC6207 in the bottom right corner too?  And perhaps another galaxy very faint about halfway between the two.

That's really lovely, great first attempt I've still not started on AP just focusing more on viewing at the moment! Hope my first attempts turn out as good

WOW! Amazing. M13 is one of my favourites but barely a tiny grey smudge from London

I once viewed it from Laughton in Sussex - 5 miles miles from the nearest light source - through a giant 12" Skywatcher reflector. It absolutely blew me away - this reminds me of that moment!

Yes, NGC 6207 and IC 4617 were unexpected bonuses that I wasn't really planning to include. Or in the case of IC 4617 didn't previously even know existed, since it doesn't really show up in Stellarium

And thanks for the comments, all

Critiques are still also welcome, I'd really like to get pointers on what could have been done better.
