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.
For so many years the beginning astronomer was forced to buy a mount that was unstable and almost useless when viewing at high power. More often than not, the frustration of using an unstable mount resulted in the telescope only being used for one night and being left in a closet to collect dust.
The Porta mount changes all that. It is one of Vixen's proudest designs. The combination of smooth movement, rigid design and stable platform makes your first use a pleasure and will bring you back to view more and more of the night sky.
The PORTA comes equipped with two fine adjustment handles for whole circle slow motion in both directions. It is useful for fine motion used in searching and tracking of celestial objects. In addition it is a great mount for terrestrial viewing.
The gear drives make it a simple matter to precisely track a planet or a ship on the horizon by simply turning the elevation and or azimuth control handles. The World-Standard dovetail attachment system on PORTA was developed by Vixen. This allows the PORTA to accept various dovetail mounted optical tubes and binoculars.
