Explore Scientific 92° Series 2" 12mm LER Waterproof EyepieceThe 92 Series 12mm LER delivers an ultra wide 92 field of view with 20mm of eye relief a combination that very few eyepieces at any price can match. At $299, this eyepiece was previously priced near $800, making its current price point extraordinary for the performance it delivers. The massive field of view creates a genuinely immersive deep sky experience while the Long Eye Relief design keeps hours long sessions comfortable. Key Features 92 apparent

The 92° Series 12mm LER delivers an ultra-wide 92° field of view with 20mm of eye relief — a combination that very few eyepieces at any price can match. At $299, this eyepiece was previously priced near $800, making its current price point extraordinary for the performance it delivers. The massive field of view creates a genuinely immersive deep-sky experience while the Long Eye Relief design keeps hours-long sessions comfortable.


Key Features
  • 92° apparent field of view — one of the widest fields available, creating an immersive "picture window" view of the sky that standard and even 82° eyepieces cannot replicate
  • 20mm Long Eye Relief — exceptionally comfortable viewing distance that accommodates eyeglasses without any field loss, rare at this field width
  • Premium multi-element optics with lanthanum glass elements for sharp, well-corrected images across the enormous field
  • 2" barrel for maximum light throughput matching the wide field's demands
  • Argon-purged waterproof housing — sealed against moisture, fog, and temperature extremes for all-weather reliability
  • Enhanced Multi-Layer Deposition (EMD) coatings on all air-to-glass surfaces with edge-blackened elements for high contrast

Ideal For
  • Deep-sky observers seeking maximum immersion — planetary nebulae, galaxy groups, and globular clusters sit within a vast surrounding star field that provides context and a visceral sense of depth
  • Eyeglass wearers who have been limited by short eye relief in other ultra-wide-field designs — the 20mm LER design is a genuine differentiator
  • Observers stepping up from 82° eyepieces who want to experience the next level of field width without paying Tele Vue Ethos prices
  • Extended observing sessions where the combination of generous eye relief and immersive field makes fatigue a non-issue

i can’t believe how long i went without this
Color: Silver, Color: Silver
i never expected how much of a difference this item would or could make in my nightly tea routine. i’m a slow sipper and would normally have to get up and microwave my mug 1-2 times depending on how willing i was to stop everything i was doing and move out of my comfy spot to remedy the impending sad lukewarm experience. YALL! the temperature really does make it taste better (i already knew that) but now i can settle into my spot in cozy PEACE and take as long as i want to to enjoy my tea. i was worried if the lower price point compared to other options on amazon would mean it may be lacking in quality or function, but NOPE! just a genuinely good deal (about $10 at the time of this review) and the features are all there. yes yes yes, go ahead and treat yourself because this one is worth it.

SO FAR SO GOOD! :)
Color: Silver
This is a nifty little product. It heats up pretty quickly and really does keep my beverages warm or hot, perhaps it's because it's an AC plug-in rather than USB. :) The options for length of time & degree of heat are VERY beneficial & it's an easy "touch" control. For someone who forgets to "turn things off", the auto shutoff is ideal! (lol) It's flat, steady & doesn't take up much room. The only drawback for me is that the entire tray gets hot, not just the part that the mug sits on, otherwise I'd have given it not 5 but 10 stars! It will be interesting to see how long it lasts though. :)

It's hot.
Color: Silver
It's hot. I like it. I make my tea in a 20 oz mug. Invariably it gets cold and I need to reheat it. Someone suggested I order a mug warmer. I chose this one. It has 3 heat settings and a 12 hr timer with auto turn off. What more could I ask for? Except that it has a low profile and easy to read and set settings, it does. Prefect.
