1.1.9. Optional Relay Adapter Box
Some older telescope drive correctors require electronic isolation between the camera and the
telescope. Other older correctors may require both normally open
and normally closed relays. For these and other events, an optional
Relay Adapter Box is available that will convert the
TTL relay output from the camera to mechanical
relays contained in a separate box that is inserted in-
line between the camera and the telescope. You
must use the 9 pin to RJ11 cable supplied with the
Relay Adapter Box to connect the box to the camera.
This cable adds a pin that will supply the 12V
needed by the relay adapter box. DO NOT USE THIS 9 PIN TO RJ11 CABLE TO
CONNECT DIRECTLY TO A TELESCOPE. The telescope may be damaged by the
12 volts on the extra pin. For direct connection to the telescope without the Relay
Adapter Box, use the STL-RC adapter plug and RJ11 to RJ11 relay cable as shown
in section 1.1.8, above.
1.1.10. Attaching the Remote Head
The Remote Guiding Head is an optional accessory for all models of the Research Series cameras.
When attached to the main camera body using the 3 foot
head cable, or the optional 6 foot replacement cable, the
Remote Guiding Head can perform all of the functions of
the guiding CCD that is built
into the camera. You control
the Remote Guider using the
same menu commands as you
would for the internal guider.
You can select which guider to
use for a self-guided image.
The Remote Guiding Head
makes it possible to self-guide using a separate guide scope, or through an off-axis guider assembly
that is placed in front of the filters. This can be useful when imaging through narrow band filters
where stars are difficult to see.
It is important to
remember that you should not connect or disconnect the
Remote Head to the camera while the power in on.
It is a
good idea, therefore, to plan
your observing session in
advance and connect the Remote
Head at the beginning of the
evening if there is any chance
that you expect to use it that
night. If you decide that you
need the Remote Head in the middle of an observing
session, it may be inconvenient to shut down the main
