I'm heading out of town for the rest of the month, so here's an image of M13 that I took on June 9th. This is 16, 3 minute subs at ISO 800 with a modified Canon 6D on my C14 at the F/11 Cassegrain focus. Guided with a Vixen VMC95L and a Celestron NexGuide V2 on a GCE mount. Stacking and processing with PI and PS (lights only.) The hi-res version is also available at:

http://www.astrobin.com/101362/B/

The seeing was maybe only 4/10, so I think that the C14 should do better under more stable conditions, but with only minimal sharpening, this image is "close." Enjoy...

John

Great shot Brian. I usually think of M13 being a fuzz ball between those two stars. You have shown that it actually extends nearly to the stars.

John, yours is a close second, IMO. I like the color contrast between the yellow and blue stars.

You guys leave the rest of us in the dust, though I do like when there are bonus objects like NGC 6307, and IC 4617in the background.

Thank you folks for the kind words. I did use some of the processing ideas expertly demonstrated in Scott's videos. As soon as I started stretching, I could see that there was a LOT of stuff there. PGC galaxies down to mag 21.

Brian, Your comment led me to look at the full scale image on AstroBin. I counted at least 12 galaxies in the background. Very cool! I also noticed a few areas that look to my eye like hot pixel trails. Is anyone else seeing this, or is it just me? See the clip below from the upper left area of your full scale image. There are several more throughout the image.

I assume these can be removed through processing. Can anyone suggest a method to to that?

Oh, and Brian, please accept my comment as constructive criticism. I hope we are all here to share and improve our skills.
