I finally have my Skywatcher EQ6-R PRO mount.
Talking to some imaging contacts, they seem to think this mount is not up to a Celestron C11 for astrophotography.
However PEP with Optec SSP3 (with its 30s integrations) is of course more forgiving than AP.
Is there anyone out there who is doing PEP on this or similar Skywatcher mounts with a C11.
The spec does claim up to 20kg load for AP. C11 OTA is 12.5kg and SSP3 adds another 1.5kg from memory so it seems well within limits to me.
