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.

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

Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.

One Tough Ball!
Color: Blue
Our dogs are loving this ball. Our 1 yr old hound is a world-class chewer and he can't make a dent in this ball. The interactive buzzing and bouncing keeps them entertained for long durations. It's a mite noisy but the barking from the 1 yr old is much louder, lol. Even turned off, they like playing with it and chewing on it. Based on the tough construction, we think it will last much longer than traditional chew balls.

My puppy’s favorite
Color: Orange
Great quality and built to last. My dog really enjoys playing with it and stays entertained for quite a while. The material is strong yet safe, and the included drawstring bag is a convenient extra for easy storage. Is colorful and my become my puppy’s favorite.

If you love your dog…don’t buy this.
Color: Orange
We have a nonaggressive English cocker. She opened the ball every time she played with it. And yes, we are closing it as hard as we can. I do not recommend this toy for any dog! This is a dangerous toy for a dog that is not supervised.
