Great bundle that I'm using successfully with PHD2
Tuesday, 23 April 2019  | 

I've mounted this onto my SkyWatcher OTA, where it is a plug-in replacement for the existing finder scope (same base to the guidescope mount). I then used one of the supplied USB cables (there is a longer one and a shorter one in the box) to connect to my laptop. Then I loaded up the software from the ZWO website to provide drivers for the camera, as well as a camera viewer which allowed me to test it out. Since my first tests were in daylight I needed to adjust the exposure time to get anything other than a white over-exposed picture, but with a bit of fiddling it worked fine.

When I tried it out at night, again I adjusted the exposure, and it picked out the moon and stars very well. Once I'd connected up my mount to the laptop as well (it's a Celestron CGEM mount and I needed a separate FTDI USB to Serial Adapater cable to do this), I was able to guide my shots using the free PHD2 software with only some very minor fiddling about, and capturing dark frames for PHD first. My first night's testing had rock solid 240s exposures, and I see no reason why I couldn't double this or more without any problem, but the moon was out so my subs would have been overexposed.

Q1. Will it achieve focus with a 1.25" prism diagonal (for example, the cheap Celestron one)?

No. Unfortunately not.
The Sky-Watcher EvoGuide 50ED will not work with a star-diagonal so is not suitable for use as a compact rich-field telescope.
