Almost 3D Observing Possible A binocular viewer turns your telescope into binoculars unlike the common and rather unnatural oneeye observing way you can observe in a fully relaxed manner without squinting and experience a stronger sense of space Equipped with Two Additional Eyepieces The device comes with two 125 inch 32 mm Plossl eyepieces secured by compression rings without scatching them a stereo viewer requires a matched pair of 125inch eyepieces other sizes are sold separately With 185x and 3x Correctors Two glass path correctors are offered they multiplies magnification 185x and 3x like a Barlow lens but it will allow for proper focusing with these two glass path correctors more telescopes can be adapted Multi Coated BAK4 Prisms The BAK4 prism is equipped with multiple layers of coating on its optical surfaces aiming to minimize reflection and enhance the contrast for deepspace or solar system objects while reducing light loss Compatible with Various Telescopes A novel optical system simplifies the focusing process even when using Newtonian telescopes short refracting telescopes and SchmidtCassegrain telescopes
