This camera is great! I bought it originally for guiding but i have even used it for some imaging (before my main imaging camera arrived).
It works really well both in the ZWO OAG-L and on a separate guiding scope.

using it fine with ekos/indi etc

Looked for another mono camera for guiding having swapped my other onto another rig
Wanted to save some money and put it towards a higher quality main camera so plumped for middle of the range ... 290MM mini
Have read the specs and reviews and the 290 mini scaled well with my guide scope.
I have only been able to test it out for just shy of 2 hours before the clouds, rain then winds came (still far too windy for proper trials)
It did however perform very well in that short period - I was imaging in the same area to get a comparison and this camera definitely picked up on a lot more stars and sharper to-boot
It did give a better 'shape' for HDR / HDF profile and did give a better guiding with comparable seeing when using the 120MM mini
The promoted figure of 30%, thereabouts, better than the 120 mini, so far, seems to be very true
A good guiding camera in my view .... Thanks FLO for a quick delivery, well packaged.

Iíve now upgraded both my 120mm Mini Guide Cameras to the 290mm MiniÖ Itís smaller pixel size and improved sensor allows guide stars to be detected with ease, I rarely get any interruptions with guiding with this camera and through a 50mm guide scope get 0.3-0.5 arc sec accuracy on both my rigs. Canít recommend it enough, itís expensive compared to the 120mm Mini but well worth the investment.

This has been a great upgrade from my ASI120-S, I'm experiencing lower noise, higher resolution - giving better star detection in guiding, coupled with the Helical focuser on my ZWO OAG it has allowed me to half the exposure time I need to get stable guiding.

Previous guidecam was the ASI120mm usb2. This is a significant upgrade. Smaller and lighter, and more sensitive. Gives me a smaller pixel scale and hence better guiding, the increased sensitivity means I have a choice of many more guide stars. Finally unlike the 120 it plays nicely with the USB2 hub on the back of my 294MC Pro, so simpler wiring. Is sensitive enough that it will work well if I ever decide to move from guidescope to OAG. Currently using it with the ZWO guidescope (280mm) which it suits well.

I used this for the first-time last night along with my new ZWO OAG. Having had an Altair Astro GPCAM previously, I wanted something with better sensitivity to pick off guide stars with my F5.8 TSQ100ED as the GPCAM sometimes struggled with just a separate F4 guide scope. When I fired up PHD for the first time I was amazed at the number of stars available in the FOV all with great SNR. As I was only really testing my setup I tried it in a few different locations and not once did I have to move the scope to find a suitable guide star. This is a fantastic, very sensitive, little guide camera and worth every penny in my view.
