Excellent guide scope
Everything in the ASI line usually just works and this one is no exception. Set up the same as all other ASI guide scopes. Works well in the ASI ecosystem and with the ASIAIR plus unit. Plug and go.

Great camera
Great camera, but prices for this things are too much, probably why there aren't as many Astrophotographers

Guide Scope Camera
Works great.

Great as a guide camera.
I use this as a guide camera in my 70mm meoptix guidescope. It works fine using ST-4 or ASCOM. The cable that snaps into the autoguide port is plenty long enough.However.... the cheesy 1 foot long USB cable is useless. Replace it with a longer ASAP. Unless you found a way to use your laptop within 6 inches of your scope........

Solid Guide / Planetary camera
Using this with the SVBONY SV165 Mini Guide Scope and PHD2. Tracks very well.I also use it on an Explore Scientific ED80 as a planetary camera. While the scope is a little short for planetary work (480 mm) I was still able to get a passable (but small) shot of Jupiter. Planning on testing with Saturn as well as Lunar and Solar pics when the weather clears.

Perfect guide scope
Nothing more to say, this is the perfect guide scope. It works flawlessly with PHD2 and has pretty good signal to noise readout, even in heavy light pollution.Possibly useful hack: put a barlow on this and make your guiding more accurate!
