The Atik 490EX is the highest resolution Atik to date and one of the most flexible ones. Featuring the latest generation Sony™ EXview HAD CCD II™ technology in an area over twice as large as before, this camera has outstanding Quantum Efficiency, very low noise, and excellent thermal management.
This model is an ideal match not only for Hyperstar systems but also for most small to midsize telescopes used by astrophotographers.
The Atik 490EX fully supports 1.25" filters down to f/2, so you won't need to replace any of your current investments in wheels or filters. This is an added advantage when looking to invest in a CCD camera that may go through multiple telescopes.
The Atik-4 Series cameras are a development of the renowned 3-Series cameras, featuring better cooling and a narrower body. They benefit from setpoint cooling to make taking matching dark frames a snap, and simple 12V power requirement to facilitate field operation. The impressive sensitivity, great cooling, and narrow profile make the Atik Series 4 outstanding CCD cameras to use on modern telescopes, including Hyperstar/Fastar systems.
