Moravian G2-8300 Mark II CCD Camera
The cooled G2 series Mark II CCD cameras were developed for imaging under extremely low-light conditions in astronomy, microscopy and similar areas. Design of this series inherits from earlier G2 Mark I cameras but brings some significant enhancements. G2 cameras employ precise electronics providing uniform frames and extremely low read noise limited only by CCD detector itself. Modular mechanical construction allows various camera variants to be combined with a rich set of accessories, including telescope adapters, off-axis guider adapters, internal or external filter wheels, Ethernet adapters, guiding cameras, etc.
G2 series of CCD cameras are manufactured with “Full Frame” CCD sensors manufactured by On Semiconductor (formerly Kodak) This model uses the KAF-8300 CCD which is known for its high resolution and dynamic range.
- An array of 3358 x 2536 (8.5-Megapixels)
- 5.4-micron pixel size
- Anti-blooming Technology
- A Quantum Efficiency of 55%
- Dark Current Doubling Temperature is 5.8℃
- A 25,500 electron well depth.
The G2 cameras have a 16-bit analog to digital converter that offers correlated double sampling to ensure high dynamic range and limit readout noise.
The USB interface offers two types for download speeds, Preview, and Low Noise, which allows you to download your full fame images in seconds. When using a USB interface, the maximum cable length is approximately 16ft. The cable length can be extended up to 49ft if you are using an active USB extender cable.
|Gain||0.8 e/ADU (1x1 binning)|
|1.3 e/ADU (other binnings)|
|System Read Noise||7 e RMS (Low Noise mode)|
|9 e RMS (Preview mode)|
|Full frame download||4.95s (Low Noise mode)|
|3.48s (Preview mode|
If the USB cable option is too short for your observatory setup, the GX Camera Ethernet Adapter allows connection of up to four GX cameras of any type through a TCP/IP and Ethernet interface, which increases the connection range to an unlimited distance.
Cooling & Power Supply
Thermoelectric cooling (TEC) can cool the CCD down to 50°C below ambient temperature. Precision regulation ensures a very low dark current for long exposures.
Moravian G2 cameras come with a 12V DC power supply adapter and a universal 100-240 V AC/50-60Hz, 60W “brick” adapter. The power connector on the camera head uses a center-positive pin.
The Moravian G2 cameras are sold in several configurations. Here are the back focus measurements for each component available at the time of purchase.
