USB 3.0

Large sensor arrays produce lots of data, so high transmission speed is required. For the ASI1600MCCool, the connection to a host computer is established via a USB 3.0 port on the camera’s rear. The USB connection can transfer the sensor’s 4656x3520 pixel array up to 23fps in 10-bit mode. A 2m USB 3.0 cable is provided.

OPTICAL CHAMBER

The camera sensor is safely located behind a sealed optical window treated with anti-reflection coatings. The sealed chamber has a set of desiccant tablets inside to absorb any moisture, which could potentially freeze onto the sensor surface during cooling. A spare set of tablets is supplied in the event that the preinstalled set needs replacing.

USB 2.0 HUB

There are two USB 2.0 ports where you’d expect to find an ST-4 compatible autoguider port. Although some still use the old port, many people connect guide cameras via USB. This can now be done with a short cable (two are provided) plugged directly into the back of the ASI1600MC-Cool.

THREADED APERTURE

The camera body has a T2-threaded ring so you can connect equipment such as filter wheels or extenders. An 11mm T2 extender ring is provided along with a T2-M48 ring. This is 18.5mm long, with a female M48x0.75mm thread, typically used for 2-inch filters. Both extenders have 2-inch external diameters. A 2-inch dust cap is included.
