Manufacturer Description

What's the difference between Tall and Tall+ versions of the Vixen Porta II Mount?

The Tall has high quality short knobs. The Tall plus (this item) has higher end long flexible knobs. The regular Porta II mount has the cheaper long slow motion cable, but they are not as nice at the type on the Tall plus.

The best Grab and Go Alt Az Mount! Vixen's Porta II Tall + Mount is a solid alt-azimuth mount with a 20lb payload capacity and features high quality slow motion flexible handles to minimize vibrations and keep your view sharp. This is very useful in searching and tracking celestial objects.

The extra height on this Tall+ mount, made possible by pairing the Porta II mount head with the Vixen AL-150 aluminum tripod, makes it ideal for long refractors or taller individuals.

The BBC Sky at Night magazine 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 different compatible tripod. In addition, this is a great mount for terrestrial viewing. With no locks or clutches, the 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 world-standard dovetail attachment system on the PORTA II mount was developed by Vixen. This allows the PORTA II to accept various dovetail mounted optical tubes and binoculars.

      5.0 What the Original Porta Should be

      Pros:

      Cons:

      Comments:

      The Porta 2 Tall + features three improvements over the original Porta 2.

      1) The tripod is taller. You can view seated with the tripod legs collapsed. Viewing the zenith with a refractor while standing is easy with the legs extended.

      2) The accessory tray is metal and attaches to each of the spreader bars, effectively locking down the tripod. This improves stability. Whacking a C80ED causes it to damp in two seconds. Under normal use (like with focusing) damp times are more like a half second or less.

      3) The flexible slow motion cables are far better built, longer, and come with large headed clamp screw heads. You can tighten these by hand and they will stay tight.

      The Porta 2 Tall + remains a light weight, smooth mount, like the original, but its improvements are very much worth it.

      5.0 Love Using the Vixen Porta II Tall+ Alt-Az Mount with My 127mm Mak OTA

      Pros:

      Cons:

      Comments:

      I'm very pleased with the Vixen Porta II Tall+ Alt-Az Mount. I like how TALL it is, so that I don't have to crouch while viewing the eyepiece in my Celestron 127mm Mak Optical Tube Assembly (OTA). The tripod is rigid and the slow-motion controls are great for tracking objects. For astronomy Outreach events, I can lower the tripod so that small children can view. I'm SO glad I purchased the Porta II instead of the Explore Scientific Twilight II Alt-Az Mount with Pier Extension.
