ZWO Mini Guide Scope

The ZWO Mini Guide Scope and ASI120MM Mini Camera are an excellent combination for my light astrophotography setup. With a SharpStar 61 and reducer, I am pushing the limit of my Star Adventurer 2i mount. I could not get it to support a heavier guiding system. The lighter system worked well, and All-Star Telescope’s prompt, inexpensive delivery system is great.

Nice Guide Scope

Bought this guide scope for my setup, along with the ZWO ASI120MM guide camera and am very happy with the results. Lightweight and easy to focus (pro tip: use a Sharpie to mark the guide camera barrel and the threads on the guide scope for easy setup), it provided for rock solid tracking. My DSO set up is a CGX Edge HD 1100 with a Starizona HyperStar v4(f1.9) and this guide scope pairs with it nicely.

It works well

It works well with the short astrophotography telescope. I use it with success with my 350 mm refractor. I guess that, as good as it is, it would not be reliable with a telescope beyond 400 mm.
