Reflector Telescope Astronomical 76700mm 525X for Adult/Kid Beginner. 1.The Telescope Works Better in Weak Light Surroundings than Ordinary Telescopes, But It Does not Work in Total Darkness. If You Mind this, Pls Do Not Buy.
2. Basic Waterproof Function Means the Telescope can Cope with Small Rain Drops or Water Drips but It will Get Spoiled under Massive Water Conditions.
3.Sharpness of separation: 1.84 Radian Per Second. (Theoretically speaking, it's able to distinguish 2 goods between 0.35in over 3280.8ft distance.
4.For the other possible Multiples: (the focal distance is 700mm)
-Eyepiece SR4mm Only = 700/4 = 175X. Matched with 3X Barlow lens = 175*3= 525X.Matched with 1.5X Erector Lens= 175*1.5= 263X zooming erect image. (Good for astronomical observation ).
-Eyepiece H12.5mm Only = 700/12.5= 56X. Matched with 3X Barlow lens = 56*3= 168X. Matched with 1.5X erector =56*1.5=84X amplification erect image. (Good for long distance seeing ).
-Eyepiece H20mm Only= 700/20=35X.
