Moravian G4 Mark II 16000 Ultimate Package
G4 Mark II cameras inherited all proven design concepts and features from the previous generation, like precise electronics providing uniform frames and extremely low read noise, efficient regulated CCD cooling, reliable mechanical shutter, modular mechanical construction ensuring compatibility with wide variety of accessories including off-axis guider adapters, external filter wheels, Ethernet adapters, guiding cameras etc. But Mark II cameras bring some important enhancements, like much faster download speeds and adjustable (tiltable) telescope adapters.
G4 cameras contain Full-Frame CCD chips OnSemi KAF with 37x37 mm detector area. These detectors are equipped with so-called “anti-blooming gate” (ABG), which drains the over-abundant charge from saturated pixels. ABG ensures the round images of bright stars, without disruptive blooming spikes. On the other side, compromising of the CCD linearity by ABG is only negligible. G4 cameras can be used for astrometric and photometric applications, and can be the ultimate camera for astrophotography.
No matter if your target is reliable scientific data or beautiful images of deep-sky objects, G4 cameras are able to provide both.
G4 series of CCD cameras are manufactured with “Full Frame” CCD sensors manufactured by On Semiconductor (formerly Kodak). This model uses the KAF-16803 CCD which is know for its large electron well capcity, big pixel size, and large surface area.
- An array of 4096 x 4096 (16.8-Megapixels)
- 9-micron pixel size
- Anti-blooming Technology with 100x suppression
- A Quantum Efficiency of 60%
- A Dark Current less than 3 electrons per second at 25℃
- Dark Current Doubling Temperature is 6.3℃
- A 100,000 electron well depth.
The G4 cameras have 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 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.

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 though a TCP/IP and Ethernet interface, which increases the connection range to an unlimited distance.
7-position 50mm Square filter Wheel
Included with this package is a 7x50mm-Square filter wheel. The filter wheel provides the best sensor coverage while offering a large number of filter postions. The large diameter pivot pin and bushings provide a smooth, quiet no-fuss operation night after night.
G4-1600 Ultimate Camera Package comes equipped with Off-Axis Guider . This adapter contains a flat mirror, tilted by 45° to the optical axis. This mirror reflects part of the incoming light into guider camera port. The mirror is located far enough from the optical axis not to block light coming to the main camera sensor.
Like all Large G4 Camera adapters this OAG features thee tip-Tilt adjustment screws. These micro adjustments allows you to make sure that camera sensor is perfectly parallel to a telescopes focal plane.
This Off Axis guider has a Female M60x1 thread to attach to the telescope
Cooling & Power Supply
Thermoelectric cooling (TEC) can cool the CCD down to 42°C below ambient temperature. Precision regulation ensures very low dark current for long exposures.
Moravian G4 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 Morivian G4 cameras are sold in several configurations. Here are the back focus mesurements for each component availbe at the time of purchase.
