SBIG Remote Guide Head

You can add a second head to your STT, STXL or STX camera and guide using a separate guide scope, camera lens or OAG. The Remote Guide Head (RGH) contains the same KAI-0340 monochrome CCD that is used in the self-guiding filter wheels for the STT and STXL series cameras, and duplicates the built-in guider in the STX. It is also the same CCD used in the ST-i guider and planetary camera. The RGH plugs into the Remote Guide Head Port on the camera body and receives its power and signals from the camera. Although the RGH looks very much like the ST-i guider, it is not the same. The RGH can only be used when connected to the RGH port on an STT or STXL camera. Also, unlike the ST-i, the RGH can control an Adaptive Optics accessory.

Remote Guide Head Camera Connection

Both the STT and STXL Series cameras have two filter wheel versions, a standard filter wheel and a self-guiding filter wheel. The standard filter wheels are specifically designed to allow enough backfocus when attached to the camera body that Nikon and Canon EOS camera lenses may be used. However, the extra thickness required by built-in guider of the self-guiding versions of these filter wheels will not allow the use of 35mm camera lenses. A standard filter wheel cover can easily be swapped for the self-guiding cover when imaging with a camera lens, and in this case, the RGH can be used in place of the built-in guider of the self-guiding filter wheel cover. Guiding images taken through a camera lens are less demanding than imaging at longer focal lengths, so using a separate guide scope in this configuration is generally fine. If you are using the STX Series camera with 50mm Square filters, the Remote Guide Head can be used with an OAG to control the AO-X.

The RGH comes with a 6 foot (~2m) HDMI cable. All ST-i guider accessories such as the c-mount and other camera lens adapters will also fit the RGH.

STX Users Please Note

Early models STX cameras used a different connector and different remote guide head than the remote guide head shown on this page. SBIG no longer makes the early version of remote guide head for these older models. You can determine the compatibility of your camera with the new remote guide head by the type of connector.
