Condition: This is a ZWO 30F4 Mini Guide Scope that's less than two years old. It's in simply excellent condition. It comes in its original box.
The ZWO Mini Guide Scope is a 30mm f/4 refractor guide scope in a small, easy to use package. It even comes ready to use with guider rings and dovetail for simple mounting. ZWO made sure this system was lightweight (1.1 lb.), allowing you to use it on most any scope or mount. Add an inexpensive brand-specific t-ring to the ZWO Mini Guidescope and attach it to your DSLR camera. It can be used as a finder with optional eyepiece (reticle or otherwise) as long as you view straight-through (no diagonal).
