This camera is the smaller brother of the popular ASI174MM, but comes in a smaller, lighter format with a 1.25" form factor, with USB2.0 connection instead of USB3.0, but other than that it would be a very good alternative for those who don't necessarily need the highest framerate and want to save a little bit of cash for some other astronomy gadget...

When used with smaller guide telescopes this camera will offer an enormous field of view; that combined with it very high sensitivity it's a no brainer that you will never soffer from not being able to find a suitable guide star in the field...

It would also make a good guide camera for a very large telescope (with long focal length) with a comparatively large guidescope... alternatively, due to it's comparatively large sensor it could also serve as a good solar, lunar or planetary imager camera when not used for guiding, and might even bring you some nice deep sky images, just don't forget that this is a monochrome camera...

We'd also recommend to read the product description of the high end version of this camera for further details and comparison of features to get an idea which one would suit you better.
