Excellent optics / Easy to use

This is now my most used eyepiece. At 30mm objects are easy to find, then zooming up to 10mm works smoothly and as well as my 10mm - all while not having to change eyepieces.

Don't Hesitate

This is a great ep at a great price, it fits in perfectly with my other 3 Svbony zooms and Baader Mark IV zoom. I use it 90° of the time in my Lunt ha solar scope and my 2" Altair Astro WL solar wedge. Even if you a collection of Hyperion / Morpheus and a 24mm Pan eps, as I do, you can't afford to not have one as a change of pace and just plain challenging fun when the expensive stuff gets boring !

A good buy!

Tried this 10-30 mm EP tonight and compared it to a different zoom EP of another brand (8-24 mm) and a 12mm Orthoscopic. It is sharp, comparable to the Ortho. It also is MUCH less sensitive to eye position than my other zoom, which makes it far more comfortable to use. The narrow apparent view angle at 30 mm does not bother me at all (but, of course, I also still use Orthos), and it is plenty wide at 10mm. Light throughput seemed excellent as well. And the adjustable lens collar is a greatly appreciated feature. This is a good buy.
