What is your opinion of Orion's "Explorer" 25X100
Posted 11 September 2013 - 04:05 PM
I think these Explorers are a steal, but want to know how they compare to the newer Giant view series offered now. I would also like to know how they compare to other offerings of current models of Garrett, Oberwerk and others in the $300 range.
These appear to be in good condition and come with the Orion Paragon tripod and the hard case for the binos. I have only looked through them at terrestrial objects thus far, and the views appear sharp to my old eyes. I am able to view while using my glasses if I press them against the folded eyepiece cup.
Any thoughts, experiences or opinions would be appreciated.

I was able to use my eyeglasses while observing and everything was visible up to the field stop (if that is correct terminology).
There was some slight color fringing at the edges of the moon (some green showed), but again not excessive IMO.
When observing stars, I was pleasantly able to get pinpoint focus on the central 60-70% of the field. After that, things got progressively worse, although I did not find it bothersome for the most part. Views were still enjoyable to my inexperienced eyes.
I found the Paragon Plus tripod to be a little short when looking near the zenith, and I am not tall (5'8"). Today, I made a riser to add to the center column and also changed out the Orion head with a Manfrotto fluid head left over from my camcorder days many moons ago.
Bottom line, I am happy with the intended purchase from my friend who has owned the binos for a few years and not used them. I am still amazed at the size of the binos, and am still getting used to handling them. They are heavy .
Thanks for looking.

I have the Zhumell 25x100 which is essentially the same bino as the Orion. My experience has been about like you describe. I'm happy with the views, and they are sharp out to 60%. I don't see a lot of CA, even when viewing the full moon. However, treat them with kid gloves because if the prism mounts on the Orions are the same as the ones on the Zhumell, they are prone to being knocked out of alignment. Pretty easy to adjust, but inconvenient. You have been warned!

I would like very much to find information on adjusting the prisms should the need arrive. I have not yet searched for anything repair related. Is there a link you could share telling how to adjust the prisms or barrel alignment?
My pair is approx 8 yrs old according to my friend from whom I am purchasing them.

This appears to be the most authoritative article on aligning binocular images with adjustments to the prism mounts:
My experience with the Zhumell is documented here:

Happy to help with the friction adjustment tip.
