M-13 three years of data

Well, I got up to my site for five nights and decided to finish a couple of images. This one M-13 is about 14 hours of RGB subs only. I wanted to get as much resolution as I could with my setup and this is about it I think.
Hope you like it.

Agreed resolved to the core and lots of crisp stars, very nicely done Floud!

A superb result Floyd. My favourite object to observe since it is easy to locate. I can see it naked eye from a reasonably
dark site and it just gets better with increasing aperture and magnification. What a gorgeous image and fantastic low-key
processing. It looks almost exactly like what one would see in the eyepiece of a large aperture short focal length telescope
on a night of the best in transparency and seeing. Definitely a keeper!

Just to compare M13 with the larger glob in the southern hemisphere, here is Ignacio's Omega Centauri. Image was taken with a 130F6.3 AP refractor, a Canon digital camera and a drizzle technique that increases resolution:

Ignacio's full post:

Last Saturday I had the most productive session in my four years of astroimaging. Perfect weather combined with a new moon, a long winter night, and a working setup, allowed me to collect about 8 hours of data on three objects. The only thing that bothered a little was high humidity and dew. But that's typical of this location, so I am used to it.

Anyway, as the seeing at dusk was quite good, I decided to revisit this old friend, Omega Cent, to try to capture some of the IFN around it, as this would be the first time I image it from rural skies. With a fully cooled canon 6D (sensor at -5°C) at prime focus of the AP130GT, I collected a bit over one hour, while the cluster was going thru the meridian up in the sky.

The set of 22 3-minute frames was processed using a new drizzle module in pixinsight, that includes pixel rejection (quite novel), to enhance resolution. There is a hint of IFN in the background, although it clearly requires a longer integration.
