SBIG ST4 Autoguider
This ST4 autoguider has extras that make a snap of finding and centering a guide star. The camera head includes a flip mirror, par focal eyepiece, XY axis positioner, and PulsGuide cross hair illuminator. To locate a guide star, flip up the mirror and look through the par focal eyepiece to find a suitable star within the fov. Focus the guide star, and then center it onto the illuminated crosshairs using the XY axis positoner. No more moving the guide scope to center a guide star. Flip the mirror back into imaging position and you’re ready to autoguider. Dark frames can be taken with the flip mirror in the auto guiding position thereby eliminating the need to cover the scope to take dark frames.
The power cord has been retrofitted with a connector so that the ST4 can be powered either with the supplied AC-DC transformer, or from a 12 V battery using the included cigarette lighter plug.
Software, instruction booklet, and all cables included.
