The stars have good color, and there is a faint galaxy -left down - as premium ! The core is very well resolved.
I liked to see that some stars inside the core are like to what I get with globulars. Some faint stars, that are very close, seems to be a little line. I thought that they are noise, but with a better look we can see that they are little stars. I reckon that this is because of resolution ability of sensor CMOS from DSLRs.
The mount did its work very well. And I believe that RCs is one of the best telescope to astrophotos. The image is very sharp, with low coma.
