SBIG ST-8300M CCD Camera - Monochrome

• Just announced! The new SBIG ST-8300M CCD Camera!
  
  
• The SBIG ST-8300M monochrome, high resolution CCD camera is based on the super-popular KAF-8300 full frame sensor, with an array of 3326 x 2504 pixels @ 5.4 microns.
  
  
• The 8300 sensor sports both microlens technology and antiblooming for improved QE.
  
  
• The ST-8300 camera body, which can also be used as a guider, is small and lightweight, has a built-in mechanical shutter, and accepts C-mount and standard 35mm Nikon lenses.
  
  
• With a USB 2.0 interface, the camera can download a full frame in about 7.7 seconds and focus with 1 second update rates.
  
  
• This camera accepts the new CFW5-8300 filter wheel as well as the CFW9 and CFW10 models.
  
  
• OPT is taking pre-orders for the ST-8300M with a fully refundable 10% deposit. OPT has received our first shipment, and we will ship those on a first-come, first-served basis. New orders, as of December 1st, should ship in February or March, 2010.

The SBIG ST-8300M (monochrome) CCD Camera is based on Kodak's KAF-8300, 8.3 megapixel, full frame CCD. This CCD array has 3326 x 2504 pixels at 5.4 microns making it ideal for both short fast optics in high resolution (unbinned) mode, and for longer focal lengths it can be binned binned 2x2 or 3x3. The CCD has both antiblooming and microlens technology to improve the effective Quantum Efficiency of the sensor. As a result it can be used in a wide variety of optical configurations. The camera electronics are USB 2.0 for fast download rates and rapid focus mode. The small light body accepts body accepts both c-mount and standard 35mm Nikon camera lenses. In addition to its imaging capabilities, it can also be used as a guider. A built-in mechanical shutter is included for automatic dark frames.

Large High Resolution Imaging CCD. The KAF-8300 CCD is approximately 18 x 14mm and has a diagonal measurement of about 22 millimeters. This is about 1.6X the image area of an ST-10 and nearly the same area as the STL-4020M. With its relatively small pixels and large image area it is ideal for wide field imaging with short fast refractors. Binned 2x2 the pixels are 10.8 microns square and binned 3x3 they are 16.2 microns square. At 2x2 the array is still 2 megapixels and at 3x3 just under one megapixel. This feature makes it possible to match the pixel size to your seeing and scope, from a small refractor to a large SCT. For most users, binning will not only help optimize the sensitivity of the CCD with their optics but also speed up the download rate.

USB 2.0 Interface: The SBIG ST-8300 will download a full frame in approximately 7.7 seconds and focus with 1 second update rates in planet mode when connected to a high speed USB port. The camera is also compatible with USB 1.1 ports albeit at a slower download rate.

I2C Accessory Port: The 9-pin I2C port allows the use of our filter wheels with the same interface. The power and commands for the filter wheel all come from the camera through this port, so there are no other cables or power supplies needed to operate the filter wheel. Also, the same software that controls the camera also controls the filter wheel. Automatic RGB exposure sequences may be set or the user may control the filter wheel for each exposure.

Mechanical Shutter: A mechanical shutter is included to facilitate dark frames. This is a necessity for anyone operating remotely, even if remotely means a few feet away from the telescope.

TE cooling: In SBIG's initial tests the camera reached a maximum of -40 degrees C below ambient in a warm room. A few degrees were then given up for regulation with the camera running at only 70% TE cooling power to maintain -36 degrees C below ambient. Because of the CCDs extraordinary low dark current, great temperature deltas are not required to achieve a dark current low enough that it becomes relatively insignificant compared to the background sky brightness. In another test, one 15 minute dark frame at -10C was subtracted from another at the same temperature. The noise remaining was a total of 15 electrons, including read noise, in the 15 minute exposure. This is exceptionally low.

36mm Filters and Filter Wheel: Due to the large size of this CCD, typical 1.25" filters are just too small to fully cover the sensor without some vignetting in the corners. This may be acceptable at f/7 or longer focal lengths, but at shorter focal lengths the effect becomes greater. For this reason SBIG will offer a new 5-position filter wheel that will hold 36mm filters. A full set of 36mm filters will be available for this camera from several of our filter suppliers: Astrodon, Baader and Custom Scientific. For those doing narrowband work, or for those with slower optical systems, 1.25 inch filters may be acceptable. In this case both the CFW9 and CFW10 filter wheels will fit the ST-8300 camera.
