Re: [SBIG] Re: e finder

Hi Kent,

About the two options of STV + efinder or Remote Guidehead + efinder.

Am I right in saying that
the Remote Guide Head can control the AO-8 adaptive optics unit when
used in an off-axis guider
such as the MOAG-ST,
whereas the STV, as a separate guider, cannot control the AO-8 unit, and
one has to use the built-in guider in
an internal tracking CCD to control the AO-8 ?

Dose it mean that if one uses the STV as a separate guider,
one should not choose the single sensor "I" versions of CCD cameras ?

Clear skies,
Stewart
