## Description

From the Manufacturer This 20mm Expanse 1.25" telescope eyepiece offers a wide field of view and superior optical performance at a bargain price. Long 18mm eye relief lets eyeglass wearers view the entire field comfortably without removing their glasses. Expanse eyepieces offer a wide 66 degrees apparent field of view to let you see more of the sky. Delivers sharp views with good color correction and high contrast. Aluminum barrel is internally blackened to eliminate internal light scattering, and is threaded to accept 1.25" Orion filters

Review: Excellent eyepiece! - I saw a review for the Orion expanse series on youtube and thought I would give it a try. This eyepiece is amazing! The 66 degree field of view is fantastic. The clarity is astounding and crystal clear. I am definitely going to invest in more sizes in this series. A must have to upgrade any beginner set. Worth the investment.
Review: Not a bad lens at all. - I bough this a few weeks ago, and I can say that I've been very satisfied with this product. This lens can fit on a Meade telescope as well as an Orion. The views are nice and sharp for its level. Got good views of Jupiter and its moons, Saturn and its rings, Mercury (too brilliant to see a clear picture of it), the Orion Nebula, and close enough star systems like Syrius and others. The only thing I must be dissatisfied with right now is the weather: I haven't had many a clear-sky night in the past couple of weeks. But the lens is good. I can't wait to find filters for it!

### ⭐⭐⭐⭐ ... 9mm Expanse for several observing sessions and I am pleased with it
*by P***R on July 29, 2016*

Used the 9mm Expanse for several observing sessions and I am pleased with it. I do just about all my observing for deep sky objects (galaxies and such) from dark skies in rural areas. With my 10 in Dob using the 9mm Expanse is like a space walk and compared to Plossl's the 9mm Expanse has as generous field of view and eye relief. My 10 in Dob is a fast f/4.5 and for less demanding deep sky objects it shows them as well as my TeleVue Plossls. I have not noticed any edge distortions in its field of view. One caution: if you eyepiece filters, in my case UHC and O-III filters, carefully screw them on and make sure the filter glass does not touch the top of the Barlowed field stop. If in doubt don't screw the filter in quite all the way. My filters screwed in all the way without any problems.
