I know someone out there has thought about how could a vixen porta mount work with a tv tripod. Has anyone figured this out or seen it done ?
First, if you have the old TV Gibraltar tripod, you need the adapter kit to get a standard photo 3/8" stud:
Other TV tripods already have a 3/8" stud and don't need the upgrade kit.
Next, you need some way to get the Porta head to mount on a standard post. Vixen makes this adapter to allow it to mount on 1/4" standard photo stud:
Finally, you need to get the 1/4" thread on the Porta adapter to couple with the 3/8" stud on the TV. You can try to replace the TV stud with a 1/4" stud, or you can use a 3/8" to 1/4" adapter like this one made by Manfrotto:
In my opinion, if the existing Porta Mount doesn't meet your needs because it is too short or not strong enough, I would just sell it and get a more stable head for use with the TV tripod.

Yes you have a point and I have considered selling.
I like Televue tripods. I'm sure others might shrug their shoulders about it but I like the way the legs ajust. Very easy, simple, clamps. The Telepod tripod is alittle diffenent but simple, no bolts and wing nuts, just a hand twist unlock/locking I even enjoy using TV upswings except when using high power. Vixen porta mount works nice for that.
So, I want to use what I already have and like and make interchangable, if possible.
Thanks again for your help.

I had a Porta and I liked the operation of the head. It worked great with a small lightweight scope on it. Unfortunately, it wasn't quite stable enough with my new scope so I had to sell it and upgrade.
It's unfortunate that the Vixen Porta photo tripod adapter doesn't have a 3/8" thread instead of 1/4" as the 3/8 is pretty much the standard. It's much easier to step a 1/4" stud up to 3/8" without any loss of stability, but the 3/8" to 1/4" requires a plate so there is a possibility of some extra wobble. But those adapters are relatively cheap so it's worth a try if the Porta head can carry the load. (Well, the Vixen is way overpriced at $60, but it's cheaper than a new mount. )
I saw a TV Gibraltar tripod with a Gibraltar 5 head in the store the other day. I was impressed with the simple, classic elegance of the design. I love the twist lock legs on my Gitzo photo tripod-I can get all three legs unlocked, extended and then locked in about 12 seconds. Much easier and faster than the twist knobs. You just have to keep them out of sand or mud or they jam up. :stuck:

TELEPOD. The metal tripod with the Gitzo-style leg clamps. Got it now.
Ok, checking the specs, it has a mounting stud that is reversible for either 3/8" or 1/4" x 20 threads. So all you need is the Vixen Porta camera tripod adapter mentioned in my post above and you can directly attach the PortaMount head to the Telepod with the 1/4"x20 stud.
The PortaMount was pushed to the limit with my Vixen ED100sf, which is 36" long and 10 lbs with 8x50 finder, diagonal, and eyepiece. But it should handle a TV 85 which weighs a pound less and is only 22". If the Telepod is sturdy enough for the load, it should work fine and will be pretty easy to carry.
Sorry to hear about the trees and the lights next door. I have a couple of neighbors with porch lights and a streetlight about 80' away but our landscaping gives me some cover. I should be happy with what I have, as things could be worse.

I did not know about the Vixen Porta camera tripod adapter before you mentioned it and never would have thought about it. Sure was a big help and may help others too.
