I bought this camera as an upgrade guide camera from my 120mc for better guiding. Excellent camera, works great. Delivery from FLO perfect as always. It arrived nestled in a foam filled box super protected. Thanks Alex and FLO for the great service.

I only bought this to replace my Altair GPCam as the ASIAIR does not support non-ZWO hardware. Works as it should and FLO were brilliant.

Excellent service. Thank you

Great quality and works superbly via my Asiair plus. Provided with superb customer service, as always, from FLO. Thanks

The camera works perfectly with my equatorial mount, received in excellent condition, well packed with fast shipping. Thank you to FLO for their professional and quality service.

I am using this camera with a small 50mm Orion guide scope (only 162mm focal length). Even with such a small scope, this is guiding my 6" Celestron scope on an AVX mount with excellent tracking. Any tracking errors are much smaller than any disturbances caused by seeing conditions so stars remain sharp on my DSLR even with 3 minute exposures (I could go as long as I want, but 3 mins is a suitable cutoff time for me). Sensitivity with this setup is amazing even with short (less than a second) exposures and never fails to find stars wherever I point the scope.

I have used one of these cameras as a guide camera and it is fine for this purpose. However I needed a low light sensitive camera to monitor the position of the scopes within the dome to ensure the aperture tracking was accurate. The ASI120 with a ZWO wide angle lens fitted running through SharpCap produces a crisp, zoomable image in near darkness, which can now be monitored remotely, given it is PC based. I notice ZWO now include right angled USB plugs, which put less strain on the connector. Thoroughly recommended.

Great Service from FLO as usual and this camera works a treat when combined with my WO Guide scope. Connected to the ASIAIR plus (also ordered and fast delivery from FLO) via my ZWO 2600MC Pro on the USB2 Guide port, I’ve managed to focus and get star sizes right down. Sure there is the more sensitive guide camera but it’s almost double the price - there’s really no need for the more sensitive version IMO as the 120 does a great job with a guide scope. Maybe I’ll get the more sensitive version if I go down the OAG route but I’d be using that with a longer focal length OTA than I currently have… Recommended for quality and service !

I have recently started astrophotography and initially I was taking photos without guiding and wasn’t able to get above 40 second subs but with the guide camera, PHD and sharp cap my polar alignment is way better and I can now usually get around 5 minute exposures before trailing.

Having not had a chance to use this outside, I've only been able to set this up on the kitchen table to ensure it connects, which it does. It's fits very nicely into the William Optics 32mm Guide Scope https://www.firstlightoptics.com/guide-cameras/william-optics-32mm-slide-base-uniguide-scope.html . I'll update more as and when I'm able to test the tracking with PHD 2.
But, all in all, this seems like a well made piece of kit, worth the money. Recommended.
