Explore Scientific 100° Series 3" 30mm Waterproof EyepieceThe 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.

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

Cheap and good
Color: Black, Color: Black
I chose the color black and it gives a really nice look, especially with the multicolor led lights around the keys. It is very easy to clean and you can shut off the keyboard to prevent any mess with the iPad. The magnet is very nice and keeps the keyboard in place. The keyboard doesn’t easily slip or anything so it holds the iPad very well. Only bad thing is that over time the iPad begins to scrape off the pain and it leaves your keyboard with some white spots all over :/ but if looks isn’t something that you care about, this is the keyboard for you. Don’t use it for gaming because there is a delay in functionality when you press a key and then try to use the pad. Also, you have to press the keys a bit harder than the usual keyboard. But for the price? This is a great item! Definitely worth my money

Great quality at a remarkable price
Color: Navy Blue
I got an iPad and was looking for a cover to protect it. I came across this case that has a Bluetooth keyboard. It seems to be working great. It was less than $30 and had 4.5 stars with over 4k reviews. The keyboard is magnetic and detachable, so I’ve got lots of configuration options. The keyboard pairs easily and allows you to use the iPad like a laptop. The point of an iPad a lot in one shot is kind of the touchscreen, but when I’m typing a lot of text as once (like now), it’s really nice to have a physical keyboard and touchpad. The keys are comfortably spaced and I’m comfortable typing on it. There is no additional setup for the keyboard besides pairing it to the iPad. At that point, all the cursor and keyboard features are immediately available. The case is well built and has nice features like a slot to hold a stylus and multiple grooves to set your viewing angle. It’s configured to be used in landscape mode, but if for some reason you wanted to use it in portrait mode, you can pop the keyboard off to lay it flat. Especially for the price, this is an exceptionally nice iPad cover.
