ASI294MC Pro

asi294Sensor

ASI294 is the first camera in the world that equiped with SONY latest sensor IMX294CJK.

294MC Pro3

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 from 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 for astronomic camera market applications that require low-illumination performance.

DDR Memory Buffer

ASI294 Pro camera includes one 256MB DDR3 memory buffer to help data transfer more stable and no amp-glow issue which is caused by the slow speed data transfer during reading out under USB2.0 Port.

DDR3

DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.

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, read noise will drop below 2e but same dynamic range(13 stops).

294 Gain RN DR FW vs gainFull 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.

Reliable Mechanics

ASI294MC Pro has same mechanics as ASI1600 Pro. There are 4 screws seal the chamber. This structure has been fully tested and it is very stable.

Even with high humidity eviroment, ASI294MC Pro will still works fine without dew problems.

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%).

Dark Current

The dark current of ASI294 is a little bit higher than ASI1600 from out test result.

ASI294 VS ASI1600

Let’s see this table to compare the difference between 294 and 1600 camera:

list

USB 3.0 Port & USB2.0 HUB

USB 3.0 Port: Provide 5Gb bandwidth to make it possible for ASI294 Pro to run at 16 fps (14bit, normal mode) or 19 fps (10bit, high speed mode)  at full resolution(11.7Mega).

We recommends 12V at 3A~5A or more DC adapter for cooler power supply(2.1*5.5, center positive).

Battery from 9-15V is also suitable for cooling power supply.

USB 2.0 HUB: can connect with various accessories, such as filter wheel, guide camera and electronic focuser, so you can manage your cable better with USB2.0 hub. There are 2 short 0.5m USB2.0 cables coming with ASI294 Pro. The power of hub source from external power supply if you connect it.

Cooling System

ASI294 Pro has 2 stage TEC cooling system to enable very deep cooling (-35? below ambient). you need external power supply to power on the cooler. AC-DC power adapter is not included in this package, you can order from here.
