QHY90A
8.6 Megapixel CCD camera
16-bit A/D
The QHY90A is an 8.6 megapixel integrated cooled CCD camera using the popular KAF-8300 4/3-inch monochrome CCD. This sensor has an array of 3358 x 2536 pixels at 5.4um. The image area is a generous 17.9mm x 13.5mm.
QHY16200A
APS-H Format 16.2 Megapixels Monochrome CCD
16.2 Megapixels
The QHY16200A uses the ONSEMI 16.2MP KAF-16200 CCD. The APS-H format is suitable for most telescopes, including SCT’s that cannot fully illuminate a 35mm frame without some vignetting or distortion at the edges. It is also suitable for commonly available 2-inch filters. The larger sensor size provides nearly twice as many pixels as the popular KAF-8300. The QE is similar to or higher than 8300 and the 37ke- full well capacity is almost 50% greater than the 8300’s 25.5ke-. yielding a dynamic range about 1.5X greater than the 8300.

SONY ExView II
79% QE
The QHY695A uses the Sony ICX695 ExView II CCD, a 1-inch, 6 megapixel sensor with a peak QE close to 80%. The read noise is as low as 4 electrons. The two-stage TEC, reducing the sensor temperature to -40C below ambient, and the extremely low thermal noise of this CCD, combine to give this camera its legendary clean images.17.9mm x 13.5mm.
