Frank,

As Dennis and Paul alluded to.....we are assuming this scope CAN
already bring things to focus?

My GSO Dob and most others, I assume, need the '50mm chop'
before I could bring something to focus (DSLR, DSII etc).
I followed Clive's (Alchemy) guide in the articles section on
how to do it to a 12" F5 Dob.

OK.....assuming your's already does focus ok, I found quite a few
weeks back that Jupiter and the DSI II needed a manual exposure
setting of 0.0005 sec in Nebulosity to bring surface features on
Jupiter in, perfectly exposed.
Anything slower and it blew out into a blob.

Hope this helps,

Steve
