> Has anyone had any experience with the Orion Star Shoot Auto Guider ?
Paul's numbers for calibration sound about right based upon my
experience with PHD Guiding and a Starlight Xpress Lodestar. Calibration
time probably doesn't depend much upon the camera, but rather the time
required to determine drift directions.
I've not used the Orion camera, but Tom Polakis reported a while back
that one he had compared poorly to other guide cameras due to low
sensitivity. Best choices at present are probably the SBIG ST-i,
Loderstar and, presumably, the recently introduced Lodestar X2.
Certainly one major improvement to the new Lodestar is the change from a
tiny little 4-pin connector on the guide port to a standard 6P6C (RJ25)
jack.
You will want to be sure your guide 'scope and primary optical system
are rigidly coupled (which includes removing any play in the focuser on
the guiding system), and that all the various cables involved are
secured so nothing shifts during tracking. You may also find a need to
adjust your drive mechanism. One of the first things a lot of people
encounter as they bring up an auto-guiding system is that backlash in
the declination axis can be a challenge.
