The
SXV guide camera
The rear panel
of the SXV-H9 provides multiple inputs and outputs, as shown. The autoguider
output is opto-isolated and will drive any standard active-low guider input via
an RJ11 'telephone' lead. The Parallel and serial socket is an 18 way latching
high density connector, which provides both power and control signals for the
external guide camera. It also carries two RS232 serial ports for external
device control. If the serial ports are not required, the guide camera may be
connected directly to this socket, otherwise a small 'port divider' box can be
connected in-line and presents the two serial outputs on standard 9 pin 'D'
plugs.

eyepiece for comparison.
The guide camera uses a 4.9 x 3.7mm CCD (1/3" format)
and will slide into a 1.25" focusing assembly. It may also be used with a
'CS' mount camera lens. The weight is less than 100 grams.
