I’m a bit new to the autofocus world and would appreciate some help setting this up. I’m doing photometry using B and V filters on a C11, with the autofocuser on the primary focus knob (i.e. no external focuser, so quite a lot of backlash). The B filter is offset about 800 steps from V in the ‘out’ direction of the mirror (CW rotation of the focus knob). Here’s what I’d like to happen for each target:
- Autofocus with V filter
- Acquire V images
- Apply the 800 step offset for the B filter then move straight to acquiring the B images (this will trigger backlash compensation since I’ve configured it to be ‘in’ since an SCT, and this is an ‘out’ move). I don’t want to autofocus with B ever as its close enough as a relative offset from V.
I think I have to:
- Enable ‘Auto adjust focus per filter’
- Enable ‘Auto focus with filter: V’
- In the Filter Setup, enter ‘Focus pt’ values for the two filters (with B 800 steps larger than V)
What not quite sure is what to set for ‘Focus with Filter’ for each filter. I assume use V for V, but do I set ‘Default’ for B?
