Starting Price: $999.00
Price as Configured: $999.00
Brand: QHYCCD / SKU: QHY-183M (100105)
QHY183 is a model designed for astrophotography beginners. It exhibits excellent sensitivity and low noise, with the back illuminated 183 having higher sensitivity and somewhat higher resolution.  It is well suited to planetary and deep-space imaging particularly when mated with the CFW3 filter wheel. This model has two-stage thermal electric cooling of the sensor to about minus 40 degrees C below ambient for maximum reduction of dark current noise in long exposures.
Price as Configured: $999.00
