skywatcher explorer 200 f/5 bobs knobs?

[alfi]

hi

i have a skywatcher explorer 200mm f/5 newt.

i was wondering if anyone know if there are bobs knobs for the primary mirror of this scope?

i have seen for the secondary, but that is not the most urgent i think, but the primary would have been nice.

Hi Alfi,

This thread should answer your questions. Bob doesn't do them, but WDS does some that do the job perfectly.

Because the primary adjustment and locking screws are so close together, you can't get knobs for both, so using springs instead of teh standard nylon washers to maintain collimation is the only alternative to using an allen key for locking.
