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.
