New cooled version of the ZWO ASI290MM/MC features the new 1.28" 2.13Mp Sony IMX290LQR / IMX291LQR back-Illuminated CMOS sensors with 2.9 µm pixels. 

"There's no doubt that this is a strong contender when it comes to Solar System imaging, with excellent deep-sky performance too. The camera has an exposure range of 32 microseconds up to a maximum of 2,000 seconds, offering exciting opportunities for chasing smaller objects such as planetary nebulae or galaxies." Pete Lawrence writing for 'BBC Sky at Night' magazine January 2017.

Improved visible light and near-Infrared sensitivity. 

Supports Full HD 1080p

Anti-reflective (AR) optical window.

Comes with a 2.5mm accessory 'all sky' lens which can provide a nearly 170° view of the sky! 

The cooler requires a 12v power supply at 2.5A or 3A max DC adapter. The camera can be used without the external power supply but will run in the normal, uncooled mode. 

All ZWO cameras include a 2-year warranty.
