Been thinking of buying some more lenses and came across this on the Orion site. I've wondered why there isn't a common telescoping lens, much like what is used with cameras, and maybe now Orion has given us one. Anyone actually buy or use one of these? Would love a review on the product.
My thoughts ... for what they are worth.
Sounds like a great idea for someone who wants more than the standard 7-8-9mm eyepieces. I know that with my Nikon cameras I have a selection of lenses that cover the 24-50mm range, 55 - 200mm, 200-700, and a big honker that is 500 to 1000mm. If this Orion zoom is as good as my Nikon, Nikko, or Tamron lenses then we've got a real winner here.
What's the word?
Zoom eyepieces are quite common. I have the SVBony, Celestron and Baader Hyperion
Reports and discussions, for your review.
How People use Zoom Eyepieces as Part of the Observing Process
Baader Hyperian Mark IV Zoom review - Quote from the review -
Over the course of testing the Baader Hyperion Mark IV Zoom, the eyepiece
showed itself to be a capable and potent observing tool. Optically it
provided a bright, high contrast, and controlled view that allowed it to
keep up with even premium wide-field eyepieces like the Pentax XWs.

zoom eyepiece review – Includes Celestron review
Quote from the review: The Celestron zoom is the bargain eyepiece in this
comparison. Yet, despite its simpler design, its optical quality is
(visually) very close to the other contenders, a tribute to good
manufacturing. There is probably a lesson in there somewhere: execute a
simple design correctly and it may be competitive with a complex design that
is harder to manufacture. (If only we had access to an optical bench, so
that we could "split hairs." -Editor.) The Celestron zoom appears to be well
made, although not in the same class as the premium Tele Vue and Vixen
zooms. The Celestron is not as smooth in operation as the premium eyepieces
and it is noisier when the zoom ring is rapidly turned from 8mm to 24mm.
However, it is much less expensive than the other zooms and performs well,
making it the standout in the "bang for the bucks" arena. If your Chancellor
of the Exchequer is a bit tight with funds, buy the Celestron 8-24mm zoom
