ZWO ASI294MM Monochrome 4/3" CMOS USB3.0 Deep Sky Imager Camera

FREE SHIPPING!

AVAILABLE FROM UK STOCK NOW!

DESCRIPTION IS UNDER CONSTRUCTION!!! At the moment it's a mixed description of the cooled and non-cooled versions, but note, this is NOT A COOLED CAMERA!

The MONOCHROME, NON-COOLED version of one of our most popular CMOS cameras has been released and will be available very soon from 365Astronomy and their dealer network.

It features a back-illuminated SONY made 4/3" sensor with 14 bit ADC and 4.63 micron pixel size that would suit well medium sized telescopes. The 66k e- full well capacity is impressive, but the nearly 90% QE (quantum efficiency) combined with 1.2e readout noise is unbelievable!

 

Similarly to the ZWO ASI1600MC camera, the ASi294MC camera would be an excellent choice for imaging deep sky objects, however it can do much more than that. With a max framerate of 16.3 FPS at full resolution this camera can also be used as an extremely high resolution planetary imager. If you cannot decide if your thing is deep sky or planetary imaging, go for this camera. It is also a much more affordable alternative to converting a dSLR.

You can even use it for guiding, although we understand that it is somewhat a waste of a talent to use it for guiding, but there might be special circumstances or setups when you would want to use it for guiding, so the opportunity is given.

There are four versions with this same large 4/3" sensor (23.2mm diagonal):

Colour cooled or uncooled and monochrome cooled and non-cooled.

This product listing is for the NON-COOLED, MONOCHROME version of the ASI294. 

If you go for this monochrome version, you'll also need a filter wheel and a set of L-RGB filters, plus H-alpha, OIII and SII filters, and maybe even H-beta filter as well for narrow band photography...

Please note that the sensor diagonal size is very close to the internal clear aperture of a 1.25" filter, therefore with extremely fast telescopes (small f-ratio) there might be vignetting. The limiting f-ratio will depend on the telescope and whether you will use any filters with this camera. Although it's a colour camera, good results can be achieved by using filters against light pollution and even H-alpha or other narrowband filters in certain setups.


Features of the NEW ZWO ASI294MM-PRO

Recommended for Deep Sky Imaging as well as the Sun, Moon and planets at very high resolution (although monochrome ASI174 would be better for the Sun)
(To image the Sun you'll have to use a proper front solar filter or Herschel wedge depending on your telescope. Please contact us if not sure!)

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.

DDR Memory Buffer

Possibly there is no DDR memory buffer as this is not the cooled PRO series, but this feature is to be confirmed!

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 capacity, which is 3 times more than the 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

The IMX294 sensor is a BSI (backside illuminated type) sensor, which has very high QE (quantum efficiency, which we estimate is over 75% peak).

 

Dark Current

The dark current of the ASI294 is slightly higher than the ASI1600, based on our test results.

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).

Recommended cooler power supply: 12V @ 3-5A (or more) DC adapter (2.1×5.5mm, center pole positive). Also suitable: DC battery with 9-15V.

Using a battery with 9-15V is also suitable for the cooler power supply.

USB 2.0 HUB: can connect with various accessories, such as filter wheel, guide camera and electronic focuser, so you can better manage your cables. The ASI294 Pro includes two short 0.5m USB 2.0 cables. The integrated USB 2.0 hub is powered by the external power source if you connect one.

 

Cooling System

This is not the cooled version, so there is no active cooling.

ASI294 VS ASI1600

The following table provides a comparison of the differences between the ASI294 and ASI1600. One cannot say which one is better as there are pros and contras for both; they are simply different. It would depend on the application, optical system used and the imaged object which camera would have to be favored.
