ZWO ASI294MC (color)
ZWO ASI294 Color CMOS Telescope Camera
4/3″ format, 14bit ADC, 63700e full well.
- Planetary and Deep-Sky Imaging.
- Pixel Array: 4144 x 2822.
- Pixel Size: 4.63 microns.
- Sensor: IMX294CIK.
The ASI 294MC is the first camera with the latest Sony IMX294CJK sensor: the ideal astro camera for every conceivable application! The "back-illuminated" Sony CMOS sensor ensures maximum sensitivity and therefore short exposure times. With just 30 seconds of exposure time and subsequent stacking, you'll be able to capture faint nebulae and galaxies with this camera - without any active cooling! The main advantages of the camera at a glance: USB 3.0 for a fast download - can also be operated with USB 2.0 Very sensitive CMOS sensor: quantum efficiency in the maximum over 75% (about 530nm) Good resolution due to relatively small pixels Supplied with AR clear glass filter, which means full passage also in the infrared. If the IR is to be blocked, an IR cut filter is needed. HCG mode - if Gain (pre-amplification) is higher than 120 (12 db), the readout noise will be reduced below 2e - Result: Despite extremely high sensitivity, you will obtain low-noise images. High full-well capacity: even bright stars do not burn anymore, they get a better signal-to-noise ratio. Big scope of delivery: adapters, cables and more
Product Description
ASI294MC
ASI294 is the first camera in the world that equiped with SONY latest sensor IMX294CJK.
Diagonal 21.63 mm (Type 4/3) Approx. 10.71M-Effective Pixel Color CMOS Image Sensor, This is the official description on Sony website. In our effort, we remolded it to make it Diagonal 23.2 mm (Type 4/3) Approx. 11.71M-Effective Pixel.
▶High-Sensitivity Type 4/3 CMOS Image Sensor that Supports 4K for Astronomic Cameras and Industrial Applications
The “IMX294CJK” is the first in-house image sensor for astronomic cameras to adopt the Type 4/3 format, and realizes output of the number of pixels needed for 4K at 120 frame/s (in ADC 10-bit output mode, ASI294MC can run up to 25fps at 4k format base on USB3.0 bandwidth). In addition, use of a large-size pixel achieves SNR1s of 0.14 lx* which is very close to the value of ASI224(0.13 lx*).
▶Exceptional low-illumination performance
Exceptional low-illumination performance of SNR1s: 0.14 lx is realized by use of a large-size optical system and by expanding the area per pixel to 4.63 µm. This makes the IMX294CJK ideal sensor for astronomic camera market applications which requires low-illumination performance.
14bit ADC & 13 stops DR
ASI294 have 14bit ADC and it can achieve 13 stops dynamic range which is even better than ASI1600.
HCG Mode
HCG mode will be on when gain is higher than 120(12db), read noise will drop below 2e but same dynamic range(13 stops).
Full well Capacity
63700e full well, which is 3 times than ASI1600’s capacity. Even bright stars won’t saturate under long exposure.
This camera can achieve higher SNR(signal to noise ratio) with just one single exposure.
High QE
IMX294 sensor is a BSI(back-illuminated type) sensor and has very high QE(we suppose the QE peak is more than 75%).
USB 3.0 Port & ST4 Port
USB 3.0 Port: Provide 5Gb bandwidth to make it possible for ASI294MC to run at 16 fps (14bit, normal mode) or 19 fps (12bit, high speed mode) at full resolution(11.7Mega).
ST4 Port: Can be used connect with auto guide port of mount, for guiding.
