Vixen Porta II Mount with Train and Track Motors
The Porta II is a solid alt-az mount with a 15 lb 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, 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 was developed by Vixen. This allows the Porta II to accept various dovetail mounted optical tubes and binoculars.

- TNT or Slo-mo, not both.
This is my second Porta II. Thought I would try this one because of the JMI (*Not* Vixen) Train-N-Track and I do a lot of high power lunar/planetary viewing. The ad copy is misleading in that one can use either the cable slow motion controls or the TNT. The cables cannot overcome the motor. I tried to see how much force would be required to over come the motors and ended up breaking both cables. So, if one wishes to use the cable slow motion controls they must first remove the TNT. Hardly convenient. More like a major design flaw.
The cables themselves work very well as I know from experience, although personally, I prefer the metal rod versions as the response is immediate since one doesn't have to wait for the "twist" to tighten up enough to turn the drive shaft.
As for weight capacity, it works well with short tube refractors and the VMC110L it is usually paired with. The longer the tube the lower the total weight it can carry but this is true regardless of mount due to arm moment. I currently have a Meade ETX-125 tube attached and it is pushing the mount's capacity even though it's a short tube and with Orion 6x30 RACI finder and base plus 40mm eyepiece only weighs 8 pounds, 5 ounces.
Without the JMI Track N Train I would give it four stars. In My opinion, the TNT is detrimental to an otherwise very good mount.

Product Questionshello, im concern about your Vixen Porta II Mount because i have celestron omni xlt152r and i don´t know the weight capacity for my telescope, i need around 30lb. can you tellme if your product can load my telescope? thank youQuestion by: ivan on Oct 30, 2014 10:31:32 AMHello Ivan,
Thank you for your question. The weight capacity for this mount is 15 pounds so it would not be a very good mount for a telescope that weighs more than that. You would be better off with an equatorial mount that can handle 30 pounds that are offered by companies such as Vixen, Celestron, and Losmandy.Answer by: Roderick (Admin) on Nov 4, 2014 12:21:33 PMHello, will this accept a NexStar8SE and all the related accessories such as finderscope, eyepieces and the occasional .5 LB DSLR?Question by: AD (Livermore, CA) on Apr 15, 2016 6:56:00 AMThe mount will be able to carry all of that gear as long as it is balanced and the total weight is under 20 lbs, but as this is an alt-az mount you will be limited in your max exposure time to ~30 seconds. An equatorial mount would be a better recommendation if you are interested in more serious astrophotography.Answer by: Chris Hendren (Admin) on Apr 15, 2016 4:55:00 PM
