If you are looking to start out with something a little larger than a beginner scope, or need a better finder scope for your large telescope, the A80Mf is the one to buy. Although it is just 10mm larger than its smaller cousin the A70Lf, this extra aperture will revel more detail in solar system objects and the deep sky alike. Use the 80mm size for terrestrial viewing of ships on the ocean or whale watching. With an optional sun projection accessory you can view sun spots projected onto a white surface. (Of course NEVER look at the sun directly). The A80MfLf, although inexpensive is not a toy telescope. It has the same quality glass and exacting workmanship that goes into the much larger instruments. The A80Mf is an Achromatic Refractor with 80mm (3.2") of aperture. Its focal length is 910mm (3 ft.) with an f ratio of 11.4. Its light gathering is 130 times better than the human eye and has a maximum (realistic) power of 144X. It weighs about 5.5 lbs.

Vixen R130Sf 130mm Diameter Newtonian Telescope Optical Tube This lightweight 5" reflector is a favorite of many new astronomers because it features remarkable light gathering with sharp images for its price and size. With a standard 20mm Plossl more than the entire moon fills the eyepiece. You'll view innumerable star clusters and dark clouds, not to mention nebulas and galaxies. Add a 32mm and the heavens open up with a remarkable 2.5 degree field of view! All of the stars in the Pleiades can be viewed at the same time. The visual observer will enjoy wide views of deep sky objects. Actual groups of nebula or clusters can be viewed at the same time with this instrument. The R130Sf comes standard with the 6 x 30 finder and dovetail tube plate that fits very well on all the Vixen mounts. This is a scope you can start with on a basic user-friendly Porta Mount and later move up to one of the electronic mounts such as the Skypod or Sphinx.
