|Meet the new G3-16200 camera (UPDATED)||Updated: 15.2.2016|
|We are proud our company could provide feedback when OnSemi designed the new KAF-16200 CCD sensor. What is so special about this CCD? Simply put, it is designed to be the best possible sensor for vast majority of astrophotographers and astro-imaging enthusiasts around the world. While there are even greater detectors available, like KAF-16803 in the G4-16000 camera, such huge sensors require at last 3" focusers and field correctors to cover them with good quality image. As opposite, KAF-16200 in the newly introduced G3-16200 camera fits within the field of view of typical 2" focusers and optical correctors, used on absolute majority of amateur scopes. And at the same time it leaves almost no field of view area uncovered, so it allows capturing of really stunning wide field images. In association with great 16MPx resolution and 6μm pixels, low read noise and dark current, above average sensitivity and especially uniform and clean field of view, G3-16200 is an ultimate imaging camera for majority of amateur telescopes.|
When the first astronomical CCD cameras, intended for amateur astronomers, were introduced, they offered tremendous quantum efficiency, showing deep space objects in a fraction of exposure time compared to film emulsion (plus huge number of other advantages, like digital image processing etc.). But they suffered from one important flaw — limited sensor area compared to film and thus limited field of view.
This situation inverted these days. Cameras like G4-16000 or G4-9000 offer CCD sensor measuring 37 × 37mm, surpassing the typical film frame area by 50%. But it is really not easy to put together optics, capable to cover such giant sensor. And CCDs do not help the situation with its ability to precisely focus images (we have immediate feedback while focusing) and to digitally process them so every optical aberration is clearly visible. Newtonian telescopes need huge secondary mirrors, 3" focusers and coma-correctors and still fast setups suffer from vignetting in the edges of the field. ED and APO refractors also need 3" focusers and field flatteners else large sensors cannot be used without significant compromises.
The G3-16200 camera continue in the tradition of Gx astronomical cameras, used for cutting-edge science as well as for the best astronomical images by professional and amateur astronomers all over the world. The G3 system contains models with internal or external filter wheels, wide variety of telescope adapters, off-axis guiding adapters, USB and Ethernet interfaces etc.
G3-16200 cameras are supported in the latest SIPS version 2.4 and newer and in the ASCOM drivers version 3 and newer.
The G3-16200 camera requires system driver gXccdF.sys version 2.0 and newer. While the camera as USB device is compatible with older drivers, its functionality is harmed if it is used with such driver. It is necessary to update the system driver to the latest version in the case some version 1.x driver is already installed on the particular PC e.g. to handle some other camera (e.g. G2-8300).
If the Gx Camera Ethernet Adapter is used, make sure the device runs firmware version 23 or newer. If some older firmware is used, update the firmware to version 23 or newer.
