Product description

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.
