The Porta II Alt-Azimuth Mount With Carry Bag from Vixen Optics provides a sturdy and stable Alt-Azimuth mount that is easy to set-up, use and transport. With its standard Vixen dovetail plate and 20 pound payload capacity, you can attach Vixen and many non-Vixen optical tube assemblies (OTAs), or bring multiple OTAs for a viewing session, and simply and quickly swap them to suit the subject. This most basic of mounts is ideally suited for quick astronomical or terrestrial viewing. Dual flexible handles control the two axis, reducing the amount of vibration while tracking. Its two 120-tooth worm gears lets the altitude and azimuth travel a full 360° circle. The Porta II operates without locks and clutches, but rather with a friction system. This means you can simply move the mount by hand to quickly find your subject, then use the slow-motion handles to track. Since many different OTAs can be mounted, there are adjustment screws on each axis to add more or less tension, based on the weight of the OTA. Also, depending on the design of the OTA, you can change the orientation of the flexible handle position to be correctly orientated for comfortable use.
An aluminum 2-section tripod comes with the mount. It has an height adjustment range from 35.4 to 51 inches. A solid center bolt lets the mount also turn a full circle and makes the mount easily detachable from the tripod to mount on heavier tripods. A nylon carry-bag, specifically designed to fit the mount and tripod, is included to make getting to your viewing spot easier.
