• Finding astronomical objects is particularly easy with the Alstar 9x50 finder scope; It provides both a bright image and comfortable viewing
• This finder scope has a 50mm aperture and so provides a particularly bright image; Objects which you are not even able to see using just the naked eye will usually become directly visible; Also if you are trying to locate one of the brighter DSOs this will no longer be able to remain hidden giving itself up to your searching eye
• A star map with reference stars with which one can orient oneself is usually used to find particular objects; Some of the stars shown on star maps cannot be seen or are difficult to see with just the naked eye however; This finder scope makes a large number of aditional stars available a big plus for being able to successfully locate objects
• The achromatic optics provide a bright true-to-life image at 9x magnification; In addition the optical surfaces have been multi-coated to prevent irritating reflections
• The 9x50 finder scope has built-in crosshairs to let you find the correct object more easily and to put it in the middle of the main telescope's field of view; The finder scope comes supplied complete with a robust mounting plate; Two adjustment screws and a compression spring allow very rapid alignment with the main telescope; Precise focusing can be achieved by rotating the objective lens.
