Starlight Xpress SXV-AO Autoguider.

Image tracking and stabilisation using a high speed tip-tilt optical window
Fast tracking speed of 5mS per increment
Overcomes rapid gear errors to stabilise even difficult mounts
Mount control output for correcting large drive errors while maintaining AO stabilisation
Image shift factor independent of optical system or camera back-focus spacing
Off-axis guider assembly (optional) for use with an SXV guide camera
STAR2000 guiding compatible
May be used to image stabilise many other makes and types of camera, given suitable
control software
Clear aperture of 37mm for up to APS size chips
Short optical length - 64mm with OAG, 38mm without.
Very low light loss (~2%) from the multicoated optics
Filter recess for adding narrow band. IR blocking or pollution rejection filters without affecting
the guide camera sensitivity
Serial RS232 control via the computer or SXV splitter box. Parallel control available
Low power consumption. Less than 600 mA at 12v DC when moving - 50mA quiescent
current
Compact and lightweight - only 112mm in diameter x 32mm long - less than 500 grams load

The SXV-AO should be used with the off-axis guider for the best results with most optical
systems. This combination uses an SXV guide head to view the edge of the telescope field
via a 10mm square prism and provides accurate positional feedback to the control software.
Unlike cameras with an integrated guider chip, the OAG puts the guide camera ahead of any
filters that the user fits into the camera ring recess and so its sensitivity is always at
maximum. The guide camera mounting is designed to be parfocal with an SX camera when
used in this combination - fine focus adjustment is provided by moving the threaded guider
mount along the prism tube.

STAR2000 cameras may be used directly without the OAG, but the AO correction rate must
be kept reasonably slow, or amplifier glow effects may become a serious issue.
