About the Vixen A80Mf w/ Porta II Mount...
If you are looking to start out with something a little larger than a beginner Vixen Telescope or, need a better finder scope for your large telescope, the Vixen A80Mf Refractor Telescope 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. You'''ll find yourself using 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 Vixen Telescope A80Mf, although inexpensive, is not a toy telescope. It has the same quality glass and exacting workmanship that goes into much larger Vixen Optics Telescopes.
A perfect Vixen Telescope for the beginner astronomer or an ideal first telescope for a child. With Vixen'''s Universal Dove Tail system, this can mount on any of the Vixen Telescope Mounts. The Vixen A80Mf with Porta II Mount 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 is easily transported to your observing site for quick set up and viewing. The Vixen Telescope A80Mf Refractor weighs about 5.5 lbs. and is covered by Vixen'''s 5 Year Warranty.
"If you are looking to start out with something a little larger than a beginner scope and want to spend the time to learn the sky instead of relying on a computer to slew the scope over to each object, this is the Vixen Telescope package for you The A80Mf attached to the Porta II Mount moves easily and is stable when stopped. No tweaking of the hand controls is necessary like some other brands. I was able to smoothly track a pod of dolphin out at sea without loosing them and took a few images with my digital camera attached to the second port on the flip mirror diagonal." Clear Skies, Mr. StarGuy
