I have managed to get my SBIG ST10 CCD camera going under INDI, and would like to use it for simultaneous autoguiding in INDI, as it is a dual chip camera.
The mount is Astro-Physics 1200 QMD (Pre-GTO version) which guides fine using the old Windows SBIG CCDOPS control program with an ST4 cable.

A few questions:
1) Can you select the same driver (SBIG CCD) also for guiding, or should I use SBIG STI for the guiding chip, is it is part of the same camera.

2) in INDI descriptions I only find a suggestion to use the 'lx200ap' driver for Astro-Physics GTOCP2 and Legacy mounts. 
   The mount as far as I know is using ST4 protocol, not lx200. So would this driver work with an ST4 guiding cable? Do I need another driver for this non-GTO legacy mount?

Happy to hear any suggestions to get it guiding in INDI,
