Konus KonusMotor 130 Reflector Telescope with RA Motor and Electronic Focuser

here we have a basic telescope which is suitable for general purpose astronomy this one is a CONUS and you'll see from the information it's 114 millimeters that's about four and a half inches focal length 900 millimeters and it gives something called an F ratio of 7.8 what that's telling you is that the focal length that's how long it's it is from the bottom of the mirror we turn the telescope round here like so I take off the cover there look if I just get this onto a wide they'll be able to see there's the mirror there it's a special mirror it's called a parabolic mirror that means that it's silvered and there's no glass on the silver so the actual amount and aluminium and silver powder which makes a very highly reflective surface that goes in a very thin layer on the mirror the mirror is parabolic is that way it focuses the light rays so it come up to this spider device here which is
