I recently received a 10 Micron 2000 HPS. It preferably uses Jnow.
Does Prism v.11 send the coords as J2000 or Jnow when communicating with the mount?
This is from the 10M mount ascom driver manual:
Code : Tout sélectionner
Use J2000.0 ICRS Coordinates: check this if you want the ASCOM
driver to report (and use) the J2000.0 coordinate system. Usually,
the driver will report (and use) the Local Topocentric coordinate
system for communicating with the client. Both choices are
ASCOM-compliant, but if you choose this the ASCOM driver will
perform some coordinate conversions internally. This will have
two effects. First, the communication between the driver and
the mount is increased, because much data is needed for the
conversion. Second, the TargetRightAscension and TargetDeclination
properties will be buffered into the driver instead of being
communicated directly to the mount.
