The ZWO ASI1600 family of cameras introduces a new class of camera to the deep sky imaging market. These cameras are very compact and lightweight, thereby making them ideal for travel and use with systems where focuser load is limited. The cameras feature a modern CMOS 4/3 sensor which provides a large field of view compared to typical budget CCD cameras, together with high sensitivity and high resolution 16 mega pixel performance. This makes it an ideal partner for the small, low f ratio scopes the camera will typically be partnered with.
The camera features a male T2 thread on its body and is supplied with both 1.25" and 2" adapters permitting connection to just about any imaging setup. The T2 thread can be used to attach a Nikon or Canon EOS lens adapter, thereby permitting direct connection of camera lenses.
Note: The ASI1600 is fitted with an Anti Reflection window infront of the sensor but this does not cut IR. Therefore for long exposure images a suitable IR cut filter should be added to prevent blooming.
In addition to DSO imaging, the camera can also be used for high frame rate imaging of the Moon and Planets. It also includes an ST4 guide port so can also be used as a super wide field guide camera. Its flexibility is therefore unmatched.
Software support is widespread due to the cameras ASCOM driver. FIrecapture supports the ASI1600 natively.
This version of the ASI1600 offers regulated 2 stage peltier cooling to a maximum of -45°C below ambient. The camera can operate on USB power alone but for cooler operation a separate 12V DC power source (2A) is required. See above an example of a 300s dark file with the camera running at -25°C
