Vixen - ED81S 80mm ED Apochromatic Refractor Telescope Package

with PortaMount

When The ED81S was introduced last year it set a new standard for 80mm APO Refractors. The
combination of better color correction from the new ED glass and brighter images from it’s fast
f/7.7 focal ratio will satisfy the most demanding visual astronomer or astro-photographer.

The new ED glass is made from environmentally friendly lead free materials. The optical tube is
very stable yet light weight. The top carry handle also includes a 1/2-20 stud for piggyback
camera mounting.

PortaMounts



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 our 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. Our gear drives it 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.
