Great service. Own three of these mini guide scopes. Work very well
Great little scope; so far no issues. Works well.
ZWO 30 mm f/4 Mini Guide Scope
Lightweight and easy to mount. Mounted on L-bracket with arca clamp to camera body. Used with ZWO AS120mm mini. Took some time to get the focal length right. Extended the front focus out nearly to the end and added the extension tube for the camera. Once I had that setup, I was able to focus just fine. Using with PHD2 and tracking went very smooth. Next test if the weather will cooperate is to use SharpCap to perform polar alignment.
Zwo mini guide scope
Easy and lightweight. Great optics give pinpoint stars.
Up and running
I'm just getting started in astrophotography and have paired this with a ZWO ASI120MM-S camera. It's mounted this on the side of a 5D Mark IV using an L-bracket and the whole system is running off a ZWO ASIAir Pro connected over wi-fi to my iPad. Very happy with how it's all working and this guide scope has made long exposures much easier.
Effective and easy
Purchased this scope to use as a guidescope when imaging with my camera with a lens rather than a telescope. Paired this scope with an ASI120mm-s CMOS camera and attached it to a universal L bracket. the camera and guidescope work well together using PHD II guiding software. Once the initial focus is set the scope needs no further adjustments. The scope/camera combo is light and portable adding very little weight to my main camera and lens set up. This makes the whole rig easy to balance and the tracking is very accurate.
