Moravian G2-8300 CCD camera

This series of G2 CCD cameras was developed especially with astro-photographers on mind. These cameras utilize sensitive, low noise Kodak KAI Interline-transfer CCD detectors with anti-blooming gates and electronic shutter with short-exposure capability.

More about the product

New model G2-8300 was added to the G2 series of cooled CCD cameras for low-light imaging applications. The KAF8300 CCD detector, used in the new camera, corresponds to the so-called “4/3 standard” and its imaging area 18.1 × 13.7 mm is the largest of all detectors used in the G2 series. High resolution (more than 8 MPx) and relatively small pixels (5,4 × 5,4 μm) makes this camera ideal for use with short focal length telescopes (or with ordinary photographic lenses). This camera is also ideal for high-resolution imaging of microscopic samples.

All key features of G2 series of CCD cameras are preserved also in G2-8300 model:

  • Lowest possible system read noise, limited by CCD chip itself.

  • High dynamic range, 16-bits digitization.

  • Efficient and precisely regulated cooling up to 50 °C below ambient temperature.

  • Ability of unattended operation enabled by integrated mechanical shutter and filter wheel supporting LRGB, BVRI or narrow-band filters.

  • Compact camera head, small and lightweight enough to be attached even to small telescopes.

  • Single-voltage power supply enabling operation from 12V battery or “brick” adapter.

  • Plug and play installation and rich software support.

  • Robust construction to sustain every-day usage.

But there are some features unique for G2-8300 model:

  • Although the KAF8300 CCD detector has Full-Frame architecture, it is equipped with so-called anti-blooming gate (ABG), which protects electron leaks from saturated pixels to neighboring pixels when a bright star appears in the field of view. This makes G2-8300 camera suitable also for astro-imaging applications.

  • The CCD imaging area is somewhat larger that the clear aperture of standard filters in 1.25 inch filter cells. Such filter cells cause vignetting in the image corners. This is why the filter wheel with 6 positions is not offered with G2-8300 and filters for 5 positions filter wheel are not standard 1.25, but larger filters with 31 mm diameter.

    31 mm filters do not cause vignetting on vast majority of optical systems, but they are significantly cheaper and more compact compared to 2 inch filters or filters in M48 threaded cells.
