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. The limiting f-ratio will depend on the telescope and whether you will use any filters with this camera. 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. (If you go for the 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.) With the ZWO ASI294MC you won't have to spend lots of time to get beautiful images, however, if you want to get the best results from this range of cameras and you have plenty of time to spare, why not to try L-RGB or narrow band photography with the monochrome version of the similar ZWO ASI1600MM or ZWO ASI1600MM-COOL. This cooled version is part of the PRO series of cooled ZWO cameras that features a DDR memory buffer. This product listing is for the COOLED version of the ASI294MC. If you would mainly use it as a deep sky imager camera, we'd also recommend to go for this COOLED version, but if you cannot afford or you'd be mainly using it as a very high resolution planetary imager, then go for the UNCOOLED version. (There is no monochrome version of this sensor.) There are two versions with this same large 4/3" sensor (23.2mm diagonal):Ĭolour cooled or uncooled. 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. It is also a much more affordable alternative to converting a dSLR. If you cannot decide if your thing is deep sky or planetary imaging, go for this camera. With a max framerate of 19 FPS at 10 bit ADC and 16 FPS at 14 bit ADC this camera can also be used as an extremely high resolution planetary imager. 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. This COOLED version of the new ZWO ASI294 is the first camera in the world that is equiped with SONY's latest 4/3" sensor, the IMX294CJK.
