Up and running in no time
Monday, 3 August 2020  | 

The scope and camera arrived safely, and last Friday was a good option for testing them . All works great, but I was a bit surprised by how far the camera needs to stick out from the guidescope tube to get into focus: I had to put the the focus ring in its most extended position, and then I need to move the camera (with extension tube) up and down the shaft of the guidescope to find the focus position (it is then still several cm out from the normal position). But, it all works fine! When focused this way, setting it up with PHD2 worked within minutes, and I have been able to make photos of M57 with up to 10 min exposure with my SW NEQ6 without PEC, 200/1000 SW PDS, and EOS 600D camera using an H-alfa filter, without any obvious trailing! Only when the moon got out, the SNR became so low that PHD2 lost the star occasionally, indicating it was time to call it a night...

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.


Please fill in the form below to ask a question.


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.
