ZWO ASI 290 LRGB Manual Filter Wheel Monochrome CMOS Camera Kit

The excellent camera that is the ASI-290MM from ZWO is made even more effective by the addition of a 1.25" manual filter wheel and a full set of 1.25" LRGB filters. This splendid quality CMOS camera is a testament to low expense, high quality astronomical imaging technology. Perfect for any astronomer interested in getting into Astro-Imaging, the ZWO ASI-290 is a quality machine using incredibly efficient sensor technology! It utilizes a new 2.9um-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.
Low Read Noise and why that's a Great feature to have

One of the most splendid 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.

Small Sensor; Big Images

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's capable of full HD imaging at 170 FPS, blazingly fast for the resolutions it's operating at! And that's it's maximum FPS, when operating at the absolute limit of it's resolution- at lower resolutions, it may be even faster! It supports a wide range of resolutions which will be listed below- but it's optimal resolution is 1936x1096.
