F30070M Monocular Professional Space Astronomical Telescope with Tripod Adjustable Lever Outdoor Monocular Barlow Lens
Parameters:
- Model: F30070M
- Aperture: 70mm (2.4 inch)
- Focal Length: 300mm f/4
- Oblique Mirror: 90 degrees
- Warp / Weft Machine and Aluminum Tripod
- The Most Highly: 38cm
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 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
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.
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.
