The Atik 4120EX is the highest resolution camera from the four series, and the highest resolution Atik Camera to date. Featuring the latest generation Sony™ EXview HAD CCD II™ technology, this camera has an outstanding Quantum Efficiency, very low noise and excellent thermal management. This model is an ideal match for Hyperstar systems, where fast f/2 imaging makes it easier than never to get good results, but can also be used with short focal length refractors and astrographs, for beautiful, wide field views of the night sky.
The high resolution is very apparent when printing images out to A3 poster size and beyond and really makes a striking visual impact. This also provides the option of zooming into different parts of an image on a computer screen to see the extra detail pop out. The Atik 4120EX is only available as a one shot color camera (OSC) as this is the format in which the small pixel size really has an advantage in faithfully recording the color of the stars and nebulae in the image.
OSC cameras allow taking a single image and seeing the color, something that would require filters and a filter wheel to accomplish with a monochrome camera. Adding a simple Infrared block filter or a light pollution filter is all you need to explore the wonders of the universe with the Atik 4120EX. The Atik 4120EX fully supports 1.25" filters down to f/2, so helping to keep costs down compared to the larger filter types. The other advantage of a OSC camera is the simplicity of processing its images. By recording color in one image you do not need to align the 3 or 4 separate images types required for LRGB or RGB imaging.
