Allan,

The standard (Optec TCF-S3) focuser on the Ceravolo is pretty good but I like the Atlas because I can use the same image train on my other scopes, the step size is tiny allowing very precise focusing and it also gives me the extra backfocus needed to incorporate more gadgets (at f/4.9 I don't think there is even room for an OAG with the std focuser).

Cheers,
Rick.
