Featuring a very low noise 20mp Back-illuminated Sony CMOS colour sensor, ultra high speed USB3.0 chipset for high framerate imaging and active cooling of the onboard electronics, the Altair Hypercam 183C V2 USB3.0 Colour Deepsky Imaging / EAA Camera is sure to win fans the world over. It is a sensibly-priced system, especially when compared to the cost and hassle of converting an uncooled DSLR and will ultimately produce superior results. These are proving very popular cameras, so if we are showing it as out of stock, please contact us to be put on our back orders list.
