ZWO ASI294MC USB3.0 Colour CMOS Camera - Sensor D=23.2 mm, 4.63 mm Pixel Size

ZWO ASI294 Colour CMOS Camera for astrophotography

ASI cameras stand for very good workmanship and have modern CMOS sensors installed. This camera uses the state-of-the-art "back-illuminated" Sony IMX294CJK sensor.

Sony specifies a sensor diagonal of 21.63 mm. However, measurements by ZWO have shown a true diagonal of 23.2 mm. The 4.3 µm pixels of the ZWO ASI294MC make this camera an all-rounder with highest sensitivity for short exposure times.

The "single shot" color camera offers more comfort, compared with monochrome cameras. Not everyone wants to follow through the laborious L-RGB technique for beautiful colored nebula or planetary images. The color cameras offer a possibility to get beautiful images without changing filters.

Advantages and features of the ASI 294MC color camera:

USB 3.0 for a fast download - can also be used with USB 2.0

Sensitive CMOS sensor with 23.2 mm diagonal

Good resolution through 4.6 µm pixels

Distance from T2 connection thread (female)to camera sensor: 17.5 mm

Comes with AR protection window - full transmission also in IR. If infrared should be blocked, an IR-cut filter is necessary.

Very high sensitivity - QE more than 75% - ideal astronomy camera for dim objects

14bit ADC

HCG mode - if gain is higher than 120 (12 dB), read noise is reduced below 2e - result: low-noise images despite extremely high sensitivity.

Full well capacity 63700e - even bright stars do not burn out anymore, you get a better signal-to-noise ratio.

Adaptions, cables, ... are included in the scope of delivery

Application ranges of the camera:

Solar, lunar and planetary images: extremely short exposure times (due to high sensitivity) freeze the seeing. Through the high resolution of the sensor, many details can be reproduced even at shorter focal length. Video astronomy is also possible.

Deep-sky images (nebulae and galaxies): Due to the high sensitivity, nebulae and galaxies are captured after only a few seconds. Despite the camera is uncooled, it is possible to obtain low-noise images with high resolution. By increasing gain (like the ISO setting of DSLR cameras), you can reduce exposure times below 30 seconds. Effects from seeing or inaccuracies of the drive are eliminated.

Question:
How to mount the camera on a tripod or dovetail bar?

Answer from Teleskop-Service:
In the center of the back of the body, there is a female 1.25" photo thread. This allows you to mount the camera on a tripod or dovetail bar (possibly via an L-bracket for binoculars):
