This was a different process.
I imaged this with the Celestron C8 but I used the Celestron 236C CMOS and did 12 30 second exposures and stacked 8 of them.
This is the resulting shot.
I was mildly surprised by this.
BTW, this is a big file.

I don't think I've ever seen this object. It looks more like a very sparse open (galactic) cluster, or just stars within this galaxy (perhaps an asterism).What is its designation? Thanks, Ed

My apologies.
This is the Hercules Cluster.

Just so every knows, the Hercules cluster is a cluster of very distant galaxies.
And not to be confused with M13, a globular cluster also in Hercules.

This was shot last night at a much lower magnification.

One night, a long time ago, before weather intervention blocked The Sun, The Moon, and The Universe from earthlings view....
I was experimenting with shorter, and shorter exposures...
The objective was to try and separate the bright mass of The Great Hercules Cluster.
The Moon was it's glaring self at 68%, so Northerly objects were my better targets, and The Great Hercules Cluster was prime for me at the time. Taunting me, wagging it's tongue at me.
So I took 4 series' of it.
Here is one... Pretty much just as it was captured with the Infinity program, through the eye of the peashooter....
(I hope you don't mind me inserting this Jim. It would be interesting to see what other bigger telescopes could resolve of this...)
From the light polluted Sleepy Dog backyard observatory...

OK, here's my M13. This was done with the Atik 460ex mono version. This was done with the Explore Scientific 102ed which has a focal length of 714mm. But we are diverging from the original post of the Hercules Cluster of galaxies which is not M13.

My original post was this cluster.
Shot with the C8, looking through my sight scope it looked huge and I tried to center it as well as I could. I think I probably only caught an edge and certainly not the center.
Add to that the CMOS camera is like shooting with a 3x Barlow and I can see why it was so open.

Nice work Jim.

Thank you Craig but I missed the center. 2032 mm and the crop factor of the 236c camera makes for a lot of magnification. I was surprised to see what I pulled from it.
Jim
Well done, I've not had a go at this one . Looks promising Jim, thanks for the heads up.
