ZWO ASI290MM Mini Monochrome CMOS Telescope Guide Camera

The ZWO ASI290 Mini is a top-notch monochrome guide camera, well suited to both planetary imaging and acting as a guider to amplify the usefulness of other astronomy instruments. Despite being qualified as a 'miniature' camera, it still operates at a high level of performance. With a peak QE over 80%, a read noise of only 1.0 e, a pixel array of 1936 x 1096, and a pixel size of only 2.9 micrometers, it qualifies as a powerhouse despite its small size. It achieves all of this while presenting a small and slender profile, taking up a minimum of space in your imaging train.

Superb quality, great for guidescope

ZWO's asi290mm mini is a great product. Generally IM a bit skeptical about stuff from a Eastern based company, but Im more than impressed with build quality, accessories and function. This works flawlessly as a guidescope for an 80mm orion on my 11" rasa. Integrates perfectly with ASIAIR and I have a beautiful tablet controlled astrophoto rig set to autopilot while I visually observe through my other scopes!

Improved my guiding!

I went from an Orion SSAG -- which was working without any problems -- to the ASI290MM-mini. First big difference is that the 290 mini is significantly smaller and lighter than the SSAG, making it easier to mount and balance. Second, the image is considerably less noisy and cleaner, making it easier to find useful guide stars. Finally, the smaller pixels (about half the size of the SSAG) result in better guiding performance than I was getting before. All in all it was a really useful upgrade, at a reasonable price, and with the usual great OPT shipping and service. Five stars!

My new best guide camera

The best part of this camera is the mini size. When used in off axis guiding, and with the spacers in front of the image camera, it can be mounted directly in front of the filter wheel. This makes for a compact image train. Although its not cooled, the camera has low noise and good sensitivity. As expected, no issues with finding guide stars with at 910mm focal length. Hoping for as good results at 2000mm FL.

Fast Delivery

I received the camera in perfect condition about 24 hours after placing the order. Of course I'm just 10 miles from the store but I was pleased to see how fast the order got processed.
