G2-8300 camera is equipped with 8.3 MPx Kodak CCD detector. Although this particular
detector has so-called Full-Frame architecture (do not mistake
full-frame architecture for full-frame detector format, which means
24 × 36 mm
CCD size), so it does not offer electronic shutter, it is equipped
with Anti-Blooming Gate, which prevents blooming—charge leaking from saturated pixels into neighboring
pixels. It is primarily intended for astrophotography applications.
Detector size 18.1 × 13.7 mm (4/3 standard) is relatively large and small
pixels 5.4 μm square are suitable for short focal length telescopes,
for instance fast APO refractors or mirror astrographs like the one of

The astrophotographer's know-how and experience is a key for
acquiring of such quality image, G2-8300 camera helps with very low
read noise (commercial cameras often offer read noise among 5 to
7 e- RMS, depending on the particular CCD detector),
efficient regulated cooling up to 50 °C
below ambient temperature, uniform frames without artifacts etc.
Embedded mechanical shutter and filter wheel make observing easier and
allow the astronomer to focus to imaging itself. Camera is connected
to the host PC with single USB cable and can be powered by unregulated
12 V DC
power supply (AD/DC wall adapter is included with the camera).
