26mm Orion Q70 Wide-Field Eyepiece
- Amazing quality 2" 26mm super-wide angle eyepiece at an unbeatable price
- Super-wide 70 degree apparent field of view gives you that unforgettable "lost in space" feeling
- Five multi-coated lens elements made of high index glass deliver sharp, high contrast vistas
- Luxurious eye relief and parfocal design provide comfort and convenience
- Beautifully made with machined housings, fold-down rubber eyeguards, and chrome plated barrels
Peering into space with a 26mm Orion Q70 2" Wide-Field Telescope Eyepiece puts your favorite nebulas and galaxies in a wonderful new perspective. Gas clouds glow and stellar clusters glitter amid a seemingly endless ocean of black space, thanks to the Q70s' super-wide 70-deg apparent field of view.
Each Q70 has five telescope lens, multi-coated, high-index glass elements for sharp, high-contrast images with excellent color correction. Eye relief is a luxurious 20mm. All telescope eyepieces in the Orion Q70 series are parfocal, so you can change eyepieces without refocusing. Machined housings have fold-down rubber eyeguards and a rubber grip band. Threaded chrome-plated barrels accept 2" filters. Two end caps are included.

Product Specifications:
|
Design
|
Ultrawide |
Different eyepiece designs allow for a wide range of features, depending on the needs of the observer. Orthoscopic and Plossl designs can provide a great quality image with a standard field of view, but may be difficult to use at higher powers while wearing glasses due to the short eye-relief. Long eye-relief designs have more elements and can be more expensive, but work very well with glasses, even at higher powers. Wide angle designs provide a larger view of the sky at the same power as a standard eyepiece. More complex designs can combine all these attributes together in a single eyepiece.

Apparent field of view
|
70.0-deg |
The edge-to-edge angular diameter of the light emerging from the eyepiece as seen by the eye. It is an inherent specification for a given eyepiece type or design. The apparent field of view of an eyepiece is directly related to the true field of view seen through the telescope; for a given focal length eyepiece, the greater the eyepiece's apparent field of view, the greater area of sky will be seen.
|
Eye relief
|
20.0mm |
The distance, measured in millimeters, between the observer's eye and the eyepiece lens in which the entire field of view remains visible. Eye relief varies with the optical design but generally increases with decreasing magnification. Long eye relief is advantageous for observers who wear glasses, as they don't have to put their eye directly on the eyepiece to see the entire field of view, nor do they have to remove their eyewear.
|
Coatings
|
Fully multi-coated |
Lenses are coated with an anti-reflective material to ensure that as little light as possible is reflected away, thus more gets to your eye. Good lenses are at least "fully coated," with a single layer of magnesium fluoride applied to each air-to-glass lens surface. Multiple layers of coatings are even more effective; the term "multi-coated" means one or more lens surfaces have multiple coatings. "Fully multi-coated" is superior because all lens surfaces are multiple-layer coated.
Mirror star diagonals are coated with a reflective material similar to telescope mirrors in order to reflect the light into the eyepiece. Standard aluminum coatings reflect between 88%-92%, and enhanced aluminum reflects 97%.
Dielectric coatings use a different process to deposit a coating that reflects 99% of the light. In addition to the higher reflectivity, Dielectric coatings are much more durable than aluminum coatings, so they last longer and can be cleaned with less risk of damage.

|
Filter threads
|
Yes |
|
Parfocal
|
Yes |
Parfocal refers to an attribute of an eyepiece set where little to no focusing is required when swapping out one eyepiece for another.
|
Field stop diameter
|
32.3mm |
The field stop is a mechanical ring in the eyepiece which provides the sharp edge to the field of view when looking through the eyepiece. The field stop diameter greatly affects the apparent field of view of the eyepiece; the larger the field stop diameter, the larger the apparent field of view is.
|
Barrel security recess
|
No |
The barrel security recess is a shallow groove or depression cut into the 1.25" or 2" barrel of the eyepiece. In the event the thumb screw holding the eyepiece in the focuser becomes slightly loose, the eyepiece will not fall out because the tip of the thumb screw will catch on the lip of the security groove.
|
Blackened lens edges
|
Yes |
Blackened lens edges in eyepieces and refractor lenses prevent unwanted light scatter inside the tube. This results in higher image contrast.
|
Rubber eyeguards
|
Yes |
|

Reviewer: Scott Tome
I own many eyepieces, many with the promise of
sharper, higher contrast images, but I always
come back to the 26mm Q70. It's just so
comfortable to use, both with my short focus
refractor and my long focal length Newtonian. The
images are as good, if not better than some
eyepieces costing much more! Very, very easy on
the eyes both during the day and at night. It's my
number one choice at public star parties!

Reviewer: Paul Frederick
This EP is great for viewing the whole
moon, star clusters, nebulae, and
galaxies. Really draws you in with the
wide angle. Do notice a fair amount of
blur around the edge of view.
26mm Orion Q70 Wide-Field Eyepiece
Reviewer: Daryl Powell
I own many eyepieces, some that cost
over six hundred dollars. The new Q-
70s totally hold their own when
compared to them. I have also used
seven different Q-70s in all sizes and
they are all very good. Not a single bad
one in the lot. In a flat field scope (RC
type) scope, they are razor sharp to the
edge!!! Ever bit as good as the
Panoptics, Meade SWA!! Very slight
curvature was seen and they were
totally free from ghosting which I see
even in my Naglers and Meades. I
disassembled all three units to check the
coatings on each element and the
blackened lens edges. All lens were
blackened and all elements were multi
coated. The design, once disassembled,
shows why they are free from ghosting
and the fewer elements contributes to
the brighter images when compared to
the same mm eyepiece of other
brands. There is very, very little to no
sign of astigmatism or coma. Chromatic
aberration correction was as good as the
other Televue and Meade eyepieces.
Contrast and detail were just as good as
the Televue and a hair better than the
Meade 4000 Plossel or SWA. The
machining of the barrels and field stops
are of the best tolerances I have seen.
These eyepieces would be worth more
than there asking price. If you have
always wanted 2 inch wide field eyepiece
of the best quality, buy this whole set
and know you just couldn't do any
better. I still can't believe they are
(sold at this price point) if you buy
the whole
set. AA+.
(Note from Orion: We do not recommend
disassembling the eyepieces.)
