EXPLORE SCIENTIFIC 100° Ar Eyepiece 20mm (2")

Product Highlights

20mm high-resolution argon-purged high-end eyepiece with 100° apparent field

  • Huge apparent field of view not only gave the observer a panoramic visual experience, but they relax the eye so the observer could pay attention to subtle details for extended periods.
  • Each 100° Series Argon-Purged Waterproof eyepiece is internally sealed and purged with inert, dry argon gas.
  • This also maximizes the life of the internal coatings.
  • Every 100° eyepiece is tested by submerging them down to 1 meter of water for 30 minutes.
  • All 100° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.
  • Dimensions and specifications of all eyepieces can be found in the pdf in the folder "media"

Product information "EXPLORE SCIENTIFIC 100° Ar Eyepiece 20mm (2")"
These eyepieces with their huge apparent field of view not only gave the observer a panoramic visual experience, but they relax the eye so the observer could pay attention to subtle details for extended periods. These ultra-wide angle eyepieces played a critical role in the military for aiming at targets, and their long eye-relief counterparts helped reduce eye injury from recoil. Each 100° Series Nitrogen-Purged Waterproof eyepiece is internally sealed and purged with inert, dry nitrogen gas to prevent internal fogging, to halt the intrusion of fine particulates and fungus, and to maximize the life of the internal coatings. To make sure, every 100° eyepiece is tested by submerging them down to 1 meter of water for 30 minutes. All 100° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

EXPLORE SCIENTIFIC Filter 1.25" YellowGreen No.11
Watching the Moon surface through the filter, the contrasts will enormously increase. Same with planet Mars. On the huge planet Jupiter, when using the filter, you can even see the contrasts between the cloud-bands and a lot more details. Starting with a telescope diameter of 8“ and a clear sight, you even get to see various details of Saturn.What ist a color Filter for and do we really need it ? Color Filters darken the light slightly, that reaches the eye or the sensor of the camera. This eliminates for instance stronger transitions. The result is that your picture turns out with more contrast which automatically shows more details.FEATURESMade from high-quality optical glassFilter glass is absolutely parallel All optical surfaces have anti reflex coatingsFilter housing from black anodized aluminumFilter threads on both ends (female/male)Multiple filters usage is possibleSCOPE OF DELIVERYColor filterProtection-case
