ASIAIR

Works fine as long as you have it hardwired to a Wi-Fi router - the built in WIFI interface isn’t reliable but the Ethernet interface is.

Fantastic for a beginner

I'm very new to Astrophotography and this thing is a HUGE blessing. I would still be struggling to get all the pieces of software and basic guiding going without this. With the ASIAIR I just plugged it all in, watched a couple tutorial videos and I'm getting good image data. I've got it controlling a Wave 150i mount, ZWO ASI120 guide cam, and a ZWO EAF driving a custom made focus belt drive for my DSLR lenses. It all works flawlessly. Getting dialed in on a solid PA is super easy. Yes you're locked into ZWO gear for cameras and EAF but for the convenience I'm ok with that. Yes the questionable use of open source is, well, questionable but ZWO has really done a good job of integrating this into an easy to use package. That said on principle this may be a blocker for some people and that's understandable. For me the convenience won out.
