ST-7E/8E/9E/10E head. The phone cable connection connects to the telescope drive to adjust
the telescope position when collecting images using Self-Guiding, and the short cable with
three wires connects to the CFW-6. The black wire of the three-wire group mates to the brown
or black wire of the CFW-6.
4.7 Battery Operation
The ST-7E/8E/9E/10E can be operated off of a 12 volt car or marine battery using a the
optional 12V power supply or using a power inverter. We have used the Radio Shack model
22-132A, 12 volt DC to 115 volt AC Portable Power Inverter (140 watt) with good success. The
camera draws 2.2 amps from the battery with this inverter, which should enable an evening's
operation from a single battery. The cooling booster, if used, draws another 2 amps. We
recommend a separate battery for the camera; using your vehicle's battery with the engine
running may add undesirable readout noise, and using your vehicle's battery without the
engine running may result in a long walk home in the dark!
4.8 ST-1001E Differences
The ST-7E/8E/9E/10E/1001E all use the same mechanical head. However, in the Model ST-
1001E some modifications are made to accommodate the much larger imaging CCD.
No Tracking CCD: All of the models mentioned above have a second CCD mounted in
the head for tracking except the ST-1001E. For ST-1001E users who need to autoguide during
exposures we recommend the STV stand alone autoguider. More information can be obtained
about the STV from the SBIG web site at http://www.sbig.com or by contacting SBIG directly
at the phone number or e-mail address on the cover of this manual.
AO-7 Compatibility: Because the AO-7 Adaptive Optics accessory uses the tracking CCD
to determine corrections, the AO-7 cannot be used with the ST-1001E.
CFW8 Filter Wheel Compatibility: Due to the large imaging CCD and corresponding
larger optical path required for the ST-1001E, 1.25" filters such as those used in the CFW8 color
filter wheel are too small for this camera. ST-1001E users may contact SBIG for
recommendations of third party filters and accessories for photometric work or color imaging.
Optical Center: The optical center of the window in the ST-1001E camera is moved
slightly towards the center of the camera. ST-1001E users should not rely on the mechanical
head drawings for the ST-7/8/9/10E cameras for this measurement. Please consult the SBIG
web site or SBIG technical support for this measurement if needed.
Two-stage Cooling with Optional Three-stage Cooling: The KAF-1001E CCD is nearly 1"
square and requires more cooling capability than smaller CCDs to maintain a similar
temperature. For this model camera an internal two-stage cooling system is standard. This
requires a larger capacity power supply than the ST-7E/8E/9E/10E. In addition, the ST-1001E
may be ordered with or retrofitted with the same optional Cooling Booster with water assist
that is used on the other cameras giving three-stage cooling, if conditions require.
12VDC Operation: The ST-1001E comes only with a 110VAC switching power supply
that provides the correct voltages and current capacity required by the camera. An inverter
should be used to operate from a 12VDC source such as a marine deep cycle battery.
