Manufacturer Description

Feature:

- Model: F30070

- Aperture: 70mm (2.4 inch)

- Focal Length: 300mm f/4

- Oblique Mirror: 90 degrees

- Warp / Weft Machine and Aluminum Tripod

- The Most Highly: 38cm

Standard 0.965 inch attachment contains:

- Eyepiece: H6mm, H20mm

- 3X the Barlow lens

- 1.5X positive lens

Note: This maximum magnification: 150X (lens focal length / eyepiece focal length x Barlow multiplier = maximum magnification)

About Multiples:

- Equipped with eyepiece: H6mm, H20mm, multiples are 300/6 = 50X, 300/20 = 15X

- If choose 3X Barlow lens together, multiples are 50 x 3 = 150X, 15 x 3 = 45X

- Plus 1.5X the positive lens again, multiples are 50 x 1.5 = 75X, 15 x 1.5 = 22.5X

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 natural 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.
