Nice shot for a small cluster Jorge. I'd say the GSO 305mm helps in that respect.

I can say, as every body say, that the dobsonian 305 mm is the best from trade mark GSO.

I bought it mainly because of a review from an Australian. Unhappily I don't remember his name, although I must thanks him for it.

Many people are saying very well about the RCs from DSO, despite its difficulty for collimation.

RC will be my upgrade... in some future day

I'm not sure RC's are the best match for a DSLR Jorge. Being slow the DSLR's thermal noise catches up with them. RC's like many hours to get an image, unlike a fast Newt that can image quicker.

Very good warning.
