Hi Bojan,
I have only taken one images with the 300 mm lens yet. In that time I used the Star Adventruer mount.

Taken at the full aperature f/4, not bad and it's a full frame photo but with the new setup I can do it much better. The only problem, the EQ6 mount is a bit to heavy to transport to dark places. I can't even get it into my car, but my girlfriend has a bigger car :-)
I must also get the system more power efficient when on battery power.
