Monoculars Telescope
Is it good to buy a spotting scope or telescope instead?
I chose a monocular 80mm objective diameter and the variable magnification from 20x to 65x, it is good for me to buy instead of a telescope? (Consider that it costs about $ 190)
It depends on what you want to watch with her. telescopes are primarily for earth observation. They are not well suited astronomical observation, mainly because they only allow one end of visualization, which forces the head and neck in awkward positions when you look at objects in the sky. They also introduce additional prisms and / or lenses that reduce the amount of light they collect and introduce optical aberrations. A 80mm lens and 65x magnification will not give you enough resolution for more than sport more like the Moon and planets, where the openings of 150mm and a magnification of 200x are the starting points for real. Here are some pages with good information on beginner telescopes: http://www.gaherty.ca/tme/TME0702_Buying_a_Telescope.pdf http://www.scopereviews.com/begin.html http://observers.org/beginner/ jrfbeginner.html For more advanced information, read Phil Harrington's Star Ware, 4th edition (John Wiley & Sons). You will have the most value for your money with a Newtonian Reflector on a Dobsonian mount, such as: ~ category_id = http://www.telescope.com/control/category/ Dobsons / pcategory ~ = telescopes / ~ VIEW_INDEX = 0 / ~ = 1000000 VIEW_SIZE http://www.skywatchertelescope.net/swtinc/product . php? Class1 = 1 & class2 = 106 Buy from a store specializing in telescopes and astronomy, either locally or online, do not buy large stores, discount stores or eBay as mostly what they sell is junk. Find your local astronomy club and try different telescopes one of their star parties: http://www.skyandtelescope.com/community/organizations
