Size Name:Space Astronomic Telescop Convenient
Feature:
-Aperture: 76mm
-Focal Length: 700mm
-Oblique Mirror: 90 degrees
-Aluminum Tripod
-The Most Highly: 150cm
Standard attachment contains:
-Eyepiece: 4mm, 12.5mm, 20mm
-1.5X/2X the Barlow lens
-1.5X positive lens
The formula:
-Objective lens focal length / eyepiece focal length x Barlow multiplier = maximum magnification
-Objective lens focal length / eyepiece focal length = magnification
Note: 1. Multiples of course are not the only, and it depends on the combination of factors aperture and focal length. (For example, if the window is big, the light is good, and the view is clear.)
2. When use 3X Barlow lens, installed Barlow lens first, and then install the eyepiece. (When install the Barlow lens, we need to move out the lid on the installation device of eyepiece.)
3. We just can choose one eyepiece to install at the same time, so does the Barlow lens.
