The Atik 490EX combines high resolution imaging with the incredible sensitivity of the Sony ICX814 sensor and versatility of the 4-Series design. The small 3,69 µm pixels are ideally matched with short-mid focal length telescopes for images rich in detail, while also displaying high performance at multiple binning levels. This opens up the possibility of working at longer focal lengths and boosting the already impressive sensitivity to capture even the faintest colour data.
Features of the 4-Series
Our 4-Series is designed in such way as to combine power and control with flexibility and ease of use. The narrow body makes them ideal for use on Hyperstar and Fastar systems whilst maintaining suitability with a huge range of other telescopes. They feature fully regulated set-point cooling which makes for easy and consistent image calibration, though they feature such low noise that dark frames are no longer even a requirement, meaning you can spend more time imaging the things that matter.
The slim, ergonomic design of these cameras naturally comes in at a low weight to help minimize stress on the corrector plate. The desiccant port is readily accessible from outside the camera for easy maintenance , and a simple 12V power requirement is complimented by low power use to help you get the most out of your imaging sessions, whether in the observatory or out in the field.
All of our 4-EX series cameras use sensors embedded with Sony EXview HAD CCD II™ technology which results in outstanding Quantum Efficiency, incredibly low read noise and excellent thermal management. These high Quantum Efficiencies make for impressive sensitivity across a vast range of wavelengths, but become particularly outstanding when imaging in narrowband, capturing stunning levels of detail in even the faintest of objects.
