The ZWO ASI290MM COOLED CAMERA  comes with a back-illuminated, 6.46mm diagonal size (type 1/2.8") Square Pixel Array Monochrome CMOS Image Sensor with IMPROVED VISIBLE LIGHT and NEAR INFRARED SENSITIVITY that supports 1080p. It also has got a two-stage active cooling that is very beneficial for deep sky imaging as it reduces electronic noise, thus providing cleaner, sharper and more contrasty images.

Sony has developed the approx. 2.13M effective pixel back-illuminated CMOS image sensors IMX290LQR and IMX291LQR with improved sensitivity in the visible-light and near infrared light regions for industrial applications.
A new 2.9 µm-square unit pixel 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).

The result is extremely low read noise, an amazing 1e at 30dB gain and high sensitivity especially in the near IR range.

The characteristics of this camera suggest that with its very high sensitivity, low noise, small pixel sizes, comparatively high resolution and very high framerate this camera might become our lead planetary imager.

It is not meant to compete with an ASI174, ASI178 or ASI185 as those are more suited for a more versatile task when imaging larger objects; i.e. the ASI174 is excellent for imaging the Sun, the Moon and other larger objects or well suited for planets when used with very large telescopes, however the ASI290 will work very well with smaller telescopes when imaging really tiny objects like Jupiter, Saturn, Mars, Venus, etc or maybe even small DSOs, especially with this COOLED version..

The ASI290MM camera comes with USB3.0 connection that gives you the opportunity to use it with newer laptops and is backward compatible with USB2.0. High framerates are not a guarantee for excellent images, but certainly helpful if other circumstances are given and especially helpful for the weather conditions of the average UK sky. There is no USB 2.0 version of this camera as that simply won't be enough to use the camera's possible high framerate, plus, for the same reason, we would really recommend to use it with USB3.0 compatible hardware as that's the only way to achieve very high framerates...Never-the-less it is backward compatible with USB2.0 computers where a lower framerate can be achieved.

Due to the high IR sensitivity and the various ways that this camera can be used, IR cut-off fiter is not built in so we would also recommend to buy it separately as well. Click here: ZWO IR Cut-off Filter


It comes with an AUTOGUIDER PORT just as many other ZWO cameras, so when you don't use it for imaging, you may use it for guiding in combination with another deep sky imaging camera!

This camera will mostly be used for imaging planets, but it can also be used for imaging small deep sky objects up to a certain level as it supports up to 2000 seconds exposure time.

Due to the fact that in a monochrome camera photons of the full spectrum hit each pixel, these produce more date for the same overall resolution, however you'll have to do a little bit of extra work with post processing. With this monochrome version, you'll also need a filter wheel and a set of L-RGB filters or H-alpha and OIII filters, and maybe even H-beta and SII filters as well for narrow band astro photography...)

IMPORTANT NOTE:

This camera can run without external power supply in normal mode (without cooling), however for best results we would also recommend to get a 12V mains power supply with 2.5A or higher current, as this is necessary for the active cooling. The power supply is available as an optional extra from us.

DOWNLOADS

On the included CD you'll find drivers and two software applications: Firecapture and SharpCap. These are both freeware and the latest versions can be downloaded from the developers' websites.
If you have any problem with installing any of the software from the CD, please download them from here:

Below is an example of a planetary imaging setup with a Imaging Flip Mirror, ZWO Filter Wheel and ZWO ASI120MM monochrome camera (obviously, you won't need a filter wheel for a colour camera...) With the help of a Variable Locking T2 Extension we could achieve parfocality.  The eyepiece holder (that is part of the Imaging Flip Mirror) is also adjustable, so with these two adjastable items we can achieve various positions of the eyepiece thus parfocality can be achieved with eyepieces of various focal lengths. To see approximately the same field, you'd have to use an eyepiece with approximately 6mm focal length. Please note that this setup might not work for a Newtonian telescope due to the long back focus requirement.
