ZWO ASI 290 Color CMOS Telescope CameraThe ASI-290MC Color Astronomy Camera USB 3.0 by ZWO:
This high quality CMOS camera is a testament to low expense, high quality astronomical imaging technology. Perfect for any astronomer interested in getting into Astro-Photography, the ZWO ASI-290 is a quality machine using incredibly efficient sensor technology! It utilizes a new 2.9 micrometer-square unit pixel which has been developed that combines a back-illuminated structure with technology for improving near infrared sensitivity to further enhance picture quality at low illumination while at the same time realizing Full HD cameras for industrial applications. This realizes two or more times the sensitivity in the visible-light region and three or more times the sensitivity in the near infrared light region than that of the existing Sony product (IMX236LQJ). What that means is that this sensor has radically improved image quality and efficiency without any increase in size or price from previous generations.
One of the most impressive features of this imaging sensor is it's incredibly low Read Noise at 1.0. What read Noise is, is interference in your pixels, distortion in the image, and general interference with your camera's final result before it reaches you. At only 1 electron of Read Noise, the image produced by this camera at the end result is remarkably free of interference, a stellar trait that really does maximize the efficiency of this camera's sensor.
Now, at only 6.46 millimeters, the sensor used in this camera is tiny- lending itself to the highly compact design of the camera as a whole. Most of the time with an astronomy Camera, a small sensor is taken as meaning poor images.
But here, that's not true at all. This tiny sensor packs a good solid punch, due heavily to the low read noise that leaves images at near their full potential quality. It is capable of full HD imaging at 170 FPS, blazingly fast for the resolutions it's operating at! And that's its maximum FPS, when operating at the absolute limit of its resolution- at lower resolutions, it may be even faster! It supports a wide range of resolutions which will be listed below- but its optimal resolution is 1936 x 1096.

Questions & AnswersAsk a Question
How does ZWO ASI-290MC connect to a telescope with 2" focusers like my ES ED127CF?
On a refractor, you would generally use a barlow lens to get to a larger image scale with this camera, and most 2" barlows come with a 1.25" reduction adapter. If you want to go right into the diagonal or a 2" extension tube, use either an OS-A2125 redu
Can you still use the camera with USB 2.0?
This camera will work on most USB2.0 connections, but your frame rate will decrease significantly (by at least half the maximum stated USB3.0 rate).
Is this camera cooled internally? Thank you.
This camera is not cooled; the cooled version is ZWO-ASI290MC-C
Which is better for planetary imaging with a 5" Mak f/15 FL =1900mm, the ASI290MC or the ASI224MC
For this scope and most small to medium telescopes, the smaller pixels and faster frame rate of the ASI290MC make it a better match for planetary imaging than the ASI224MC.
Will this be a good camera for planetary imaging with my new Celestron 9.25 edge and CGX-L mount?
The ZWO-ASI-290MC is a great choice for Planetary imaging, it is their highest rated camera for Planetary in fact. Take a look: https://astronomy-imaging-camera.com/asi-products-comparison/ For the price, I love this camera. It is easy to use and great
