Messier 13 , a globular cluster

The first time I saw that globular cluster was many years ago, when I had a small telescope, a classical 119/1000 (actual they were 119/900, but mine was a 119/500 with a Barlow lens inside), and I stayed really amazed.

Recently I saw again the same globular cluster with the Meade SN 8", and the sight was really different and much more beautiful, but nothing compared with a photo, where you can see many things like a galaxy and thousands of stars. I know my picture isn't very good, I've lost a lot of signal during the post-processing, so I'd have to work better in order to improve the final picture. Of course, if you have some pieces of advise to give me, I'll be all ears.

The picture has been taken with an APO refractor (a triplet lens with a field flattener) and the ASI294MC camera. The guide camera was the ASI290MC with a 60/240mm guide scope.

I don't have taken so many light frames, so next time I'll try to take them again, in order to improve the S/N.

What do you think?

Finally Sony has revealed its new camera, and never will be the same story. With this new monster Sony has created a new generation of Alpha camera, doing a step further in the mirrorless camera. As a wildlife photographer having a complete silent shutter capable of shooting 30fps is very fantastic and woould give me the opportunity to capture every single moment of an action, like a bird taking off or a landing on a perch. But you need to be careful, because its price it's very "professional", and it won't be for everybody, not me at least and not for now, unfortunately.
