Teleskops Imaisen F30070M, reflektora

Feature:
- Model: F30070M
- Aperture: 70mm (2.4 inch)
- Focal Length: 300mm f/4
- Diagonal Mirror: 90 degrees
- Maximum height with tripod: 38 cm

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 Configuration:
- Moon Filter: Because there is a lot of reflected light interfering our observation of full moon, so we can use the moon filter to avoid the interference, and then the moon's surface will be seen more clearly.
- Please screw the moon filter into the threaded of eyepiece lens' lower part, and then connect the eyepiece lens with zenith lens.

About lenses:
- 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:
- Lens focal length / eyepiece focal length x Barlow multiplier = maximum magnification
- Lens focal length / eyepiece focal length = magnification

Installation sequence:
1. Put up tripod, then attach the lens tube.
2. After the tube is fixed, install the finderscope (for preliminary search of the target object), then install the eyepiece (choose one from the two).
3. After find out the big goal, then debug with different eyepieces.
