>>3576731I saw the lx2 version a while a go, seems legit. For wide angle to medium telephoto it seems ideal. It's basically a modern take on the Barn door mount.
The accuracy will depend on your tripod, the weight of your camera set up and polar alignment. It's a bit late here so I can't delve too deeply into the specifics of the new model at the moment but I'd be interested to hear how you get on with it.
If they've done the clockwork mechanism right along with the drive system it should be better than an electric quartz driven system. According to the blurb it looks good. Fine tuning the polar alignment will help.
Polarfinder.com is a good app/program.
I noticed it's a "Sky and Telescope hot product for 2019". I haven't read the article yet. Keep us informed anon.
