The 100° Series 30mm is the largest and most immersive eyepiece in the Explore Scientific lineup — a 3" barrel design delivering the widest possible views with a 100° apparent field of view. This is not a conventional eyepiece; it is a premium wide-field instrument that transforms how you see the sky. Large nebula complexes, Milky Way star clouds, and sweeping star fields fill the eyepiece from edge to edge with a panoramic sense of depth that smaller eyepieces simply cannot create.

The premium multi-element optical design maintains sharp, well-corrected images across the full 100° field. The 3" barrel format delivers maximum light throughput and the widest true field of view achievable, making the most of large-aperture telescopes. Argon-purged waterproof construction keeps the optics sealed and clear through temperature swings, dew, and humidity — a practical advantage for an eyepiece that will spend long hours at the telescope during deep-sky sessions.

At $999, this is a serious investment — but comparable hyper-wide-field eyepieces from Tele Vue carry similar or higher price tags without waterproof construction. For observers who prioritize the wide-field deep-sky experience above all else, the 100° 30mm delivers it at the highest level.


Key Features
  • 3" barrel — the largest barrel format available, delivering maximum light throughput and the widest true field of view possible
  • 100° apparent field of view — hyper-wide panoramic views that create a genuinely immersive experience unlike any smaller eyepiece
  • Premium multi-element optics — high-quality glass types maintain sharpness and correction across the enormous 100° field
  • Argon-purged waterproof housing — sealed against moisture, fog, and temperature extremes, protecting a significant optical investment
  • Enhanced Multi-Layer Deposition (EMD) coatings on all air-to-glass surfaces with edge-blackened elements for maximum contrast
  • Fold-down silicone rubber eyecup for comfortable eye positioning during extended sessions

Ideal For
  • Dedicated wide-field deep-sky observers who want the absolute maximum field of view and immersion available — this is the pinnacle of the ES eyepiece lineup
  • Large-aperture Dobsonian owners with 3" focuser capability who want to unlock their telescope's full wide-field potential
  • Observers who have experienced 2" ultra-wide-field eyepieces and want to take the final step to the widest possible views
  • Star party centerpiece — the 100° 30mm consistently creates the most memorable viewing experiences of any eyepiece in a collection

Worx very well!
Style: Lawn Edger w/(1) 4.0 Ah Battery
Worx very well. ;) More power than I expected from a 20v cordless machine. And with the 4Ahr battery it comes with, I was able to do the drive, walks, and patio without having to change batteries. I own 2 Worx string trimmers, chainsaw, hedge trimmer, drill impact driver, and leaf blower. Love them all.

The product is great once u figure out how to assemble. The instructions don’t do it. I was not happy. Every part was a challenge. The instruction book only shows a photo but not how to get it to look like the photo.

Loved Lucky & Lexie!!
Format: Kindle
Oh my, what an absolutely amazing book!! It’s such an emotional, poignant, and heartfelt romance and Bella has really out done herself! Geez, once you I started this book I could not put it down. Lucky Beneventi and Lexie Sinclair been friends from childhood. There has always been a connection between them, yet there was also something that kept them as friends … even if they both craved for more. Lexie is returning home from Paris after spending time there studying at Le Cordon Bleu. Returning home she will be the new baker at Sweet Temptations. The past year away from home Lexie has become independent. Learning to live her life on her own terms in spite of her having Cystic Fibrosis. Excited to be back home Lexie is still a bit nervous about sharing the house with former BFF, Lucky. Lucky is now the star QB for the Kings and teammate and best friend with Lexie’s brother Linc. Though Lucky may have always had is eye on Lexie it was the unwritten rule that she was off limits for him because of her brothers. Needless to say, this has led to Lucky becoming a big-time ladies’ man. But what happens when Lexie returns from Paris and they find they are now become roommates? It doesn’t take long for Lucky and Lexie to have an unexpected late-night meeting. It didn’t take long for them to fall into easy conversation… along with a bit of bantering. It felt good to see them both open up and ease back into their old familiar friendship. But was it truly just the friendship in which they were interested? Lexie had always wanted Lucky to see her beyond just being friends. At the same time she had a real issue with having CF that kept her from pursuing more than friendship with Lucky. Little did she know that Lucky had always had visions of her being his endgame!! It was heartbreaking just how vulnerable Lexie was when it came to having a romantic relationship. Even though Lexie would fight Lucky pushing to have more with her, once he got beyond that wall, I loved just how caring and devoted he was to her. The chemistry between Lucky and Lexie was just so freaking electrifying!! And to see how thoughtful and caring Lucky was… ~swoon!!~~ These two were meant to be together. There were many other things I loved too!! The group text messages and camaraderie that were always going back and forth… This is one of the things that Bella does so well in her books. Family/friendships and extended family. Plus, all that love that you feel from them.
