90ED Astronomical Telescopes Objective diameter 90mmED Focus length:630mm

A true multi-purpose astronomical telescope

Overall performance: excellent optical design, precision machining, F-7 short focal ratio design, convenient to carry.

1: Double separation of the lens structure, contains a piece ED(Extra-low Dispersion)Glass, effectively control the color difference

2: Traditional low cast technology, guarantee the sharp image quality.

3: Lens surface ultra high transmittance broadband coating.

4: Aluminium mirror tube, spray high-grade white pearl paint, delicate and beautiful.

5: High precision nc machining the objective lens.

6: 2 inch 1:11 two-speed toothless the focuser, smooth precise.Can rotate 360 degrees in the back seat, and convenient operation.

7: Lens cap and dovetail plate, can meet the standard of astronomical bracket, can also be used with camera tripod.

Extra-low Dispersion glass; BFP63090ED Telescope is designed with Double separation lens structure ED glass; will give you the crystal clear image;BFP63090ED 90ED telescope produces an especially colour true and high contrast image; just right for more discerning observers

Dual-speed rack and pinion focuser;The gear ratio of the dual speed 2-inch toothed focuser is 1: 10; which makes it easy to achieve accurate focus

Top-quality Material; The appearance of the is baked with high-end fine-grained paint; with exquisite appearance and delicate feel;all machined by CNC

all optical surfaces multi-coated; The whole optical lens adopts the technology of ultra-wideband multilayer coating; 90mm aperture; fully multi-coated ED optics deliver outstanding views; day or night

Areas of application; 90mmED F: 7 astronomy telescope would be better begin for astronomy amateurs to do astrophotography
