Atik 420M Monochrome CCD Camera - Sony ICX-274
The Atik 420 is the first camera in its class to offer high performance regulated cooling, low power consumption and narrow body all in one. It is particularly well matched with the 6 and 8 inch HyperStar systems, where the narrow body and low heat dissipation make a difference, or with short focal length refractors, providing a very fast, high definition wide field of view. And without the price tag.
The Atik 4-Series cameras are a development of the 3-Series cameras, featuring a narrower body. These are particularly suitable if the camera is to be placed in front of the telescope in HyperStar or Fastar systems, as well as on custom-designed systems that need a narrow-bodied CCD camera. The cameras feature setpoint cooling to make taking matching dark frames a snap, and simple 12V power requirement to facilitate field operation.
The Atik 420 is a perfect match for short focal lengths. HyperStar/Fastar systems and small refractors with focal reducers are among the instruments of choice for this camera. Featuring the narrowest body in its class, the Atik 450 is one of the lightest cameras as well. But don’t think there was a compromise regarding cooling performance or stability. The cooler module has been engineered for low power use, making your field sessions last longer. Also, the desiccant port is now easily accessible from the exterior.
Included With The Atik 400 Series CCD Camera
The Atik 420 comes with Atik’s renowned Capture application which provides a simple and intuitive yet powerful way to acquire images. Tools include a focus assistance readout, image sequencer, guide camera control and integration with Atik filter wheels. Capture aims to take the stress out of imaging, making your time at the telescope more enjoyable. If you require compatibility with other software there are plugins for MaxIm DL and Astroart, as well as a full ASCOM driver.
Also included is Dawn, Atik’s new image-processing software. Like our cameras, it was designed from the ground up to be powerful yet easy to use. It allows a sequence of image-processing steps to be represented in the form
of a pictorial workflow which can be created with a few mouse clicks and can then be executed very easily for repeatable and speedy results.
About The Sony ICX274 Interline CCD Chip
The ICX274AL is a diagonal 8.923mm (Type 1/1.8) interline CCD solid-state image sensor with a square pixel
array and 2.01M effective pixels. Progressive scan allows all pixels' signals to be output independently within
approximately 1/15 second, and output is also possible using various addition and pulse elimination methods.
This chip features an electronic shutter with variable charge-storage time which makes it possible to realize
full-frame still images without a mechanical shutter. Further, high sensitivity and low dark current are achieved
through the adoption of Super HAD CCD technology.
Applications: Still cameras which require high resolution, etc.)
