Selling Astronomical Telescope. Look at the Moon crust, Planets and stars in the sky

I have my old 6 Inch Reflector Telescope for sell 6 Inch mirror dia F=10 Equatorial Mount having motor drive for one axis finder telescope very ruged and heavy near abt 45 Kg Made by P. Deodas And Co.Chennei.This telescope is very good for Planes observation and research.Iwant to sell it Because of heavi weight. not able to carry it.

I want to sell my worlds bigest brand new binocular In the comarcial. it is very good for long distance bird watching as well as for nature study the world famous orion I bought but it is heavy not possible to hold in hands so tripod is recomanded. so I am selling it If any body Interested call me pls dont call me for barganing.

I want to sell my own 102 mm refractor telescope its focal length is 900 mm f=9 very good condition I want to sell only optical tube you make your own stand I will give two eyepieces free of cost with telescope 1) 25 mm 2) 9 mm as well as 45 degree star digonal tube rings. this telescope is usefull for wildlife and bird watching also. This telescope has 2 Inch Rack and Pinion focusar. and adoptor for 1.25 Inch eyepieces.I am upgrading my Telescope.

protos space telescope.it is a reflector telescope of focal length 700mm.it has 3 lenses-6mm,16mm,25mm with it and 2X barlow lens and 1.5x erecting lens.It includes tripod stand and manuel with it.You can see planets and moon clearly(jupiter,saturn,venus,mars).

hardly used professional telescope bought from Chennai Astronomy Club 3 years back. Contact for more information.

Galileo Telescope Makers,   Leaders in Astronomy industry. Largest Astronomy and Telescope company founded and run by Astronomer in India. Gallileo 7x25 Star Finder Telescope  A  Finderscope  is a small auxiliary telescope mounted atop the main astronomical telescope and points in the same direction. Finder usually has a smaller magnification then the main telescope can provide and therefore can see more of them sky. This helps in locating the desired astronomical object in the sky. Finderscopes usually comes with a designation number like 6x30. Where 6 is the magnification and 30 is the aperture of the finderscopes objective lens in millimeters.  Includes: 25mm achromatic objective, eyepiece to give 7x magnification, crosshairs, focusing mount, unique adjustable mounting bracket with collimation set screws. Note: The Specifications and colors may vary due to recent improvements in design. Check out my  other items !

Galileo Telescope Makers,   Leaders in Astronomy industry. Largest Astronomy and Telescope company founded and run by Astronomer in India. Main features: Magnification factor: 4x Lens:  Single Concave 1.25” (32mm) fitting diameter. Fully glasses for excellent image contrast and light transmission. Plastic Dust caps to keep optics dust free when not in use. The  Barlow lens, named for its creator, the English engineer Peter Barlow, is a diverging lens which, used in series with other optics n an optical system, increases the effective focal ratio of an optical system as perceived by all components after it in the system. The practical result is that inserting a Barlow lens magnifies the image dust free when not in use.  In its astronomical use, a  Barlow lens  may be placed immediately before an eyepiece to effectively decrease the eyepieces focal length by the amount of the Barlows divergence.Since the magnification provided by a telescope and eyepiece is equal to the telescopes focal length divided by the eyepieces focal length, this has the effect of increasing the magnification of the image. Astronomical Barlow lenses are rated for the amount of magnification they induce. Most commonly, Barlow lenses are 2x or 3x but adjustable Barlows are also available. The power of an adjustable Barlow lens is changed by adding an extension tube between the Barlow and the eyepiece to increase the magnification. The amount of magnification is one more than the distance between the Barlow lens and the eyepiece lens, when the distance is measured in units of the focal length of the Barlow lens. A standard Barlow lens is housed in a tube that is one Barlow focal-length long, so that a focusing lens inserted into the end of the tube will be separated from the Barlow lens at the other end by one Barlow focal-length, and hence produce a 2x magnification over and above what the eyepiece would have produced alone. If the length of a standard 2x Barlow lens tube is doubled, the lenses are separated by 2 Barlow focal lengths and it becomes a 3x Barlow, if the tube length is tripled, the lenses are separated by 3 Barlow focal lengths and it becomes a 4x Barlow, and so on. A common misconception is that higher magnification equates to a higher-quality image. However, in practice, the quality of the image generally depends on the quality of the optics (lenses) and viewing conditions, not on magnification.
