I use a Scopetronix "MaxView 40" eyepiece with a
Scopetronix-provided step ring and adaptor tube to mount my Olympus
C-4000 to my Orion Apex 102. I have been very pleased with the
results. I've posted some photos here:

Very interested in your telescope/C-4000 combination. Have been
thinking about a scopetronic kit for my C-750, but I really needed
your illustrations to make up my mind.
I have been fudging moon shots with the B-300 teleconverter and 4 x
digital zoom. Exposure for half a moon works out about 1/400 second
at 5.6. You quote 1/200 sec at f2.8. - Goodbye handheld pot shots.
