Starlight Xpress SXVR-H694 Cooled CCD Camera

SXVR-H694 Major features:

• Medium format, high resolution 'Exview' CCD chip, with 6,050,000 x 4.54uM square pixels in a 15.98mm diagonal array. 
• Exceptionally low dark signal - No dark frames necessary for most deep sky objects.
• Exceptionally effective anti-blooming with minimal effect on linearity and no lost active area.
• High speed USB 2.0 interface for approx. 5 second downloads.
• Very high sensitivity - 77% QE at peak of response in yellow light, 65% at Hydrogen alpha line (656 nM).
• Built-in autoguider interface and output - compatible with our optional dedicated external guide cameras.
• Built-in dual serial ports for accessory control - directly drive filter wheels, GOTO 'scopes etc.
• Single USB cable control for all features - get rid of that dangerous cable tangle!
• Very low power consumption. Less than 1 amp at 12v DC.
• Compact and lightweight - only 75mm in diameter x 70mm long - less than 500 grams load on the telescope.
