Vixen Optics- PORTA II Alt Az Mount with Slow Motion Controls


Vixen PORTA II Mount (Item #5863) Sturdy Grab and Go Lightweight Altazimuth Mount

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 changed 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 Universe Today says "The Porta Mount II is quality through and through, it's not going to just fall apart on you and it would be oh-so-easy to adapt any number of other scopes right to it just as easily as the R130Sf went into place."

The Porta II is a solid altazimuth mount with a 20lb payload capacity and features Slow Motion Flexible Handles to minimize vibrations and keep your view sharp. This is very useful in searching and tracking celestial objects. The Sky at Night says: "When moving the telescope around the sky with this mount, we found any vibrations quickly dampened down. The whole system was very stable, even when the tripod was at its maximum extended height"*. The mount head is easily removed to allow for a switch to a heavier tripod. In addition, this is a great mount for terrestrial viewing. With no locks or clutches, our gear drives make it a simple matter to precisely track a planet or a ship on the horizon by turning the elevation and/or azimuth control handles. The Porta II Mount features slow motion control of both axes, solid central bolt for easy tripod change, flex handles and accessory tray.

The Train-N-Track (TNT) system for the Porta Mount is a basic alt-az motor drive system with adjustable or trainable tracking. With alt-azimuth mounts, the motor speeds will vary greatly depending on what area of the sky you are viewing. The TNT motor drive system includes adjustable speeds on both axes and high speed centering. The friction drives also allow you to move the telescope around by hand without unlocking any clutches. You just let go and the drive takes over. With a little practice, objects can be kept in the eyepiece for 10 minutes or more. The Porta Mount TNT is battery driven using 8 AA batteries and includes complete instructions. Installing the motors on the Porta II Mount is simple.
