I've got what I can only presume to be the same eyepiece labelled as a Seben. It feels pleasingly solid to hold and operate. Views of the moon through similarly cheap scopes are very sharp at 24mm-16mm and hold up fairly well at the 8mm. My only criticism is that from ~20-24mm the field stop is in view and thus the real field size doesn't increase, though of course you are still gaining a larger exit pupil. For the price, it's probably petty criticism. :)

Cheers,
Cam

The Zhumell 1.25" 8-24 Zoom is one of my favorite eyepieces and represents a great value for money spent. I'm very impressed with its optical quality and mechanical build. I use it all the time for solar observations since it allows me to finely tune magnification to match the current seeing conditions.

An important feature on this eyepiece ... not found under its listed specifications ... is the male T-Thread located under the removable rubber eye guard. This eyepiece can be attached directly to any camera that has a T-Ring Adapter ... allowing for eyepiece-projection photography. Also, the zoom magnification can adjusted without changing the camera's orientation ... very convenient!

Here's a shot of a water tower ... located 1.5 miles from my home ... taken through a Meade EXT-125 f/15 Maksutov scope. The top image was taken at prime focus (f/15, no eyepiece)... the middle image with the zoom set at 24mm ... and the bottom image at 8mm.

This was the first eyepiece I bought...I still have it. This is one of the most highly underrated eyepieces out there. It does what it was designed to do, and does it well, and at a price point within reach of everyone...can't ask for a better deal then that...

I thoroughly enjoyed you article Jon, I have the same scope and was looking for something to make it quicker to use as a grab and go, and on the cheap! Thanks :bow:

I own the 1.25-inch Orion 7-21mm equivalent of this eyepiece, which I use quite often for grab and go, casual gazing and star hopping. It currently retails for about $20 more than the 1.25-inch Zhumell 8-24mm, however the fact that the Zhumell couples directly to any camera that has a T-Ring Adapter is a huge advantage in my estimation. Both have 4 elements and long eye relief, however the Zhumell boasts 40 to 60 degree field of view while the Orion advertises 30 to 40 degrees of apparent field of view. Looks like a new ocular is in my immediate future. Thanks for the review John.

I'm in favor of cleaning the eyepiece before taking pics for a article. :foreheadslap:

I like the threads under the eyecup.

Yes a nice eyepiece indeed
I had the Celestron for a long time and have been very happy with it.
It looks identical ;)

Sounds interesting. Is the Zhumell zoom parfocal from 8-24?
