Attaching to the Telescope
At the front of the
CFW-9
you can attach any T-Thread based
adapter that will connect to your telescope, including the nosepiece
from your camera. When using a nosepiece to slip the camera and
filter wheel assembly into an eyepiece holder, you need to pay
careful attention to insure the weight of the filter wheel with the
camera attached is held in place securely with the eyepiece holder's
retaining screws. A safety strap is recommended. SBIG also sells an
optional T-Thread Visual Back Adapter which screws directly onto
the back end of the popular Schmidt-Cassegrain telescopes. This
makes for a very rigid mounting.
After attaching the camera/filter wheel combination to the
telescope, you should then drape the Camera's head cable over the
fork of the telescope and clip it in place so that the cable doesn't drag
on the ground as the telescope rotates. Also avoid hanging the
camera head and filter wheel by the cables as this could overly strain
the cables.
Positioning the Filter Wheel
The motorized
CFW-9
filter wheel is positioned using
commands in the CCDOPS software's Filter menu. The unit does
not require calibration like older models and is auto-homing at
power-up. You need to tell the CCDOPS software that you are using
the
CFW-9
and this is accomplished by selecting the
CFW-9
as the
filter wheel type in the Setup command of the Filter menu. If you
have an older version of CCDOPS that does not show the
CFW-9
you
should update your software and drivers by downloading the latest
version of CCDOPS and Driver Checker Utility from the SBIG web
site.
