Had a couple Far Canal moments with the camera.
First was with the Skywatcher 150mm achromat. If you don't know it, it is a DINOSAUR of a scope - LONG! Anyway, was slewing to a target, didn't think, as was watching laptop. CRCRCRCRCRCRCRCRCCRC. Yup, camera headbutting tripod legs. No damage except to pride.
Next was using GSO extension tubes on a Vixen (with the correct step down compression ring), which is a BAD idea, because GSO undercuts are NOT in the right place for Vixen (nor any Skywatcher I used either!). The Camera, attached to the tube, slid out.... luckily I had my rubber mat on the pebblecrete driveway (saves my knees doing alignments).
Third time was similar to above. Scope slewed to near zenith. Camera decided gravity was winning, especially with that crappy GSO extension tube. This time I CAUGHT it.
So, lessons learnt, using all Vixen adaptors etc. Impossible to come out/off, as they screw in.
