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 reveal more detail in solar system objects and the deep sky. I find myself using the 80mm size for terrestrial viewing of ships on the ocean or whale watching. With an optional sun projection accessory, I have viewed sun spots projected onto a white surface. (Of course NEVER look at the sun directly). The A80Mf, although inexpensive, is not a toy telescope. It has the same quality glass and exacting workmanship that goes into Vixen's much larger telescopes.
