The 2" diameter barrel Explore Scientific 100°-Series 5.5mm Eyepiece (2")from Explore Scientific 100°-Series 5.5mm Eyepiece (2")is an ultra-wide field telescope eyepiece designed for planetary and deep-space observations. Its wide exit pupil makes this eyepiece ideal for comfortable viewing for extended periods. The contrast is enhanced by a fold-down rubber eyecup that prevents stray light from leaking into your eye. Anti-reflective multicoated optics ensures bright, high-contrast images with true color transmission across the entire wide field of view. The eyepiece features a textured surface for a sure-grip when changing it out, argon-filled body for water and fogproof performance when used in extreme temperatures and climates, and a double-tapered barrel for smooth insertion and removal from the focuser.

[2"] I have other ES eyepieces but this is my first 100°. It truly is a thing of beauty, but it's the size of a 12oz pop can. If you have a reflector (I'm sing an Edge HD 8) be prepared to add some counter weight to the front of the dovetail. 5

[100°] Have other Explore Scientific 100 eyepieces and love them all! 5.5mm version added to use with my ED152 refractor telescope. Sharp and a wide field which makes it more comfortable for observing the deep sky. 5

[2 lb] For the 2 inch crowd this is an eye piece you need in your collection. 5

Karl	04/08/2024
[2 lb] This is my first 2" EP and my first 82 degree FOV EP. The view of the double cluster (I could see both in the FOV with my Meade LS-8) was simply spectacular. I was a little anxious about spending close to $300 for an EP. However it is definitely worth the money. 5

[2 lb] Great ep for friends who wear eyeglasses. Long eye relief, great views. 5

[100°] Very clear edge to edge view. Very please with the value of this eyepiece. B&H exceeded my expectations with shipping I received it next day with free expedited shipping. Thanks! 5

[2 lb] I replaced my 2 inch 30mm GSO in my 8 DOB with this ES eyepiece and the clarity massively improved. Colors are good in Orion's nebula and a lot of Andromeda fits in it. This is my go to eyepiece for general looking around. Built like a tank and weighs as much as one. This eyepiece will out live me. 5

[2"] Just tried this eyepiece out in my 20 inch Dobsonian telescope. We were in the very dark skies in northern Nevada. Views were excellent. This eyepiece has made my scope an entirely new experience. 5

Konstantin	26/06/2024
[2 lb] I put this eyepiece on my Celestron EdgeHD 8. It is about the widest FOV that I could pull off the OTA. The view is really crisp with point stars to the edge. I can't see any edge brightening or vignetting. The resolution is enough to clearly see the four stars of M42 Trapezium, Jupiter bands, Saturn rings, and even, barely, Saturn cloud bands. The eye relief is comfortable to view the entire field, without glasses. This is a hefty piece. Not a problem on an 8 SCT, but may be awkward on a smaller OTA. 5
