Starlight Xpress SXV-AO-LF Active Optics Standard
|The SXV-AOLF Active Optics guider views the edge of the telescope field via a 10mm square prism to provide image stabilization for astrophotgraphy. |
The highly successful SXV-AO has been updated to allow it to be used with large format cameras. The new SXV-AO-LF has a clear aperture of 59mm and will fully illuminate the H35 and H36 sensors. The SXV-AO-LF replaces the original smaller SXV-AO.
The SXV-AOLF should be used with the (included) off-axis guider assembly for the best results with most optical systems. This combination uses an SXV guide head or Lodestar 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 a Starlight Xpress camera when used in this combination - fine focus adjustment is provided by moving the threaded guider mount along the prism tube. If you do not need the OAG barrel (e.g. when using a camera with a built-in OAG or guide chip), you can fit the 72mm or T adapter directly onto the rear of the AO assembly.
