Astrophysics Portable Piers
Posted 27 January 2011 - 03:23 PM
Anyone have experience with these that can comment on their stability in relation to a sturdy tripod like the HD or FHD?

I considered the Eagle1 portable pier, but that only goes from 32-36" high, and I need a taller pier for my f/12 refractor. Particle Wave makes a portable pier that is very highly regarded (pwtec.com) but I've heard that delivery may be slow.
I'm with you.... undecided!

I have a parallax pier for my AP1200, it is very nice and stable. No struts, and not too wide of a footprint. Might be worth looking at it.

Even when I had my CGE, I never raised any of the tripod legs more than I needed to level the mount. When I'm using the GEM, I'm doing AP, not visual observing, so height doesn't really matter as much as stability to me.
I don't do this sort of thing very often, but I'd suggest to you that there's very little out there that's more stable than the Losmandy HD Tripod.

Was also looking to justify the price difference between the AP piers and the HD, particularly the folding HD.

Well.., I can't comment on how you would view the justification for one over the other, but what can I say? Its a rock solid tripod and I would have thought it'd be a question of finding reasons why not to choose this option..,

The A-P pier is lighter and very stable. I don't really worry about leveling the unit because after you do the polar alignment, the GEM doesn't care if it's level or not. I have never had a cable snag the struts, either.
The Losmandy tripod is a great, sturdy unit and if you need multiple height options, it's the best choice.

I've attached a picture of my scope sitting atop a 10" diameter Astro-physics portable pier:

Or just reply to his add on Astromart now running in the Tripod related classified adds area of that website. I bought a TRI36H from him last year. Alas, I have not yet had an opportunity to use it extensively.
Check out Rob Miller's new tripod offerings. You can contact him through Catamount Systems.

Not for larger mounts.
Well, you can get the Eagle folding pier, but the price is ridiculous.
I have a Meade Giant field tripod that I adapted to use with my AP mounts as well. It's nice in that it folds up but it is quite bulky to transport and takes up a lot of space.
The G11 tripod is probably the best of both worlds. Solid and breaks down into a more easily transportable package. Setup is faster then the AP pier.

As far as leveling, carry a few blocks of 2"x4" and you can put one or tow under a foot as needed.
But if I was doing over, the Losmandy HD would be my choice for the convenience of adjustable heights, less to take apart and put together, and easier leveling.

I have been to P.W.T. and have a portable pier on order. The engineering, workmanship, and quality are second to none! You will not be dissapointed.

Astro-physics will only sell complete piers.
That's not accurate - Give them a call.
I have ordered new center posts and extra struts as needed.

Notice how unlevel this site is, look at my trailer behind me. I still had to put a block under the adjustable foot on the parallax. This was at Peach State Star Gaze 2008.

ANYHOW one of the real nice things about the G11 tripod is the substantial area underneath it to put your power supply and eyepieces. That's real nice you can get everything out of the way of wandering feet of yourself or kids or whatever.

Has anybody got experience with the even bigger (7" diameter pier, 3.5" diameter legs and weighing ~66lbs) tripod that Losmandy make for their Titan mount?
