The Vivitar 50x 100x Refractor Telescope makes a great companion at sporting events, under the night sky, or on a bird watching trek. This article will talk about the MPN, key features and some miscellaneous data.

The MPN (manufacturer's part number) is explained by first talking about what a part number is exactly. A part number is a unique identifier of a part used in a particular industry. Its purpose is to simplify referencing to that part. A part number unambiguously defines a part within a single manufacturer. This unambiguous definition is called the MPN. The Vivitar 50x 100x refractor telescope's MPN is 1607225.

The Vivitar 50x 100x refractor telescope's key features are the finderscope (optical), max useful magnification (x 100) and optical design (refractor).

The Vivitar telescope's finderscope is a small auxiliary telescope mounted atop the main astronomical telescope and pointed in the same direction. The finderscope usually has a much smaller magnification than the main telescope can provide and therefore can see more of the sky. This helps in locating the desired astronomical object in the night sky. Some finderscopes have cross hairs to mark exactly where the main telescope is looking. The vivitar's finderscope is optical vs digital with a 3x magnification.

The Vivitar telescope's max useful magnification is x100. What this actually means is far too complicated for this article but you can Google "What does "magnification" actually mean?" to find out more.

The Vivitar 50x 100x telescope's optical design is refractor. A refracting or refractor telescope is a dioptric telescope that uses a lens as its objective to form an image. The refracting telescope design was originally used in spy glasses and astronomical telescopes but is also used in other devices such as binoculars and long or telephoto camera lenses.
