Quote:No mount can expose 5-10' unguided. A minute of two at best. Tom Mathis showed me PEC the chart of his MI-1250 with the optional high precision encoders. This is a $60K mount. He guarantees peak to peak error is less than 5 arc seconds. Anyone else that makes similar or better claims in a geared mount is blowing smoke. Think you'd be happy with the Mach1, but a GM-8 might do the job for less.
Quote:Hi Adam,The Mach1GTO is the premier mount for its class. As long as you come in with the right expectations, you can't go wrong.Speaking of which, you should never buy a mount with the expectation of not guiding. It can be done with mounts like the ASA DDM60/85, but those are even more expensive, large, and robust mounts that require a computer and special software to run. It can also be done with mounts like the Mach1GTO, AP900/1200, Paramount ME, MI-250, MI-500, etc., but never out of the box. It requires extremely accurate polar alignment, lots of PEC training, correction for atmospheric refraction, and even then you won't always be able to get away with 5-10 minutes at long focal lengths.The sign of a quality mount isn't just the total amount of PE. It's also the regularity, smoothness, and "slowness" of the PE. Fork-mounted SCTs from Celestron and Meade are difficult imaging platforms because their tracking errors are not only large, but also abrupt and fast. You can get some great images from those scope/mount combos but, generally speaking, a much higher percentage of subexposures must be discarded due to tracking errors (if you're looking to create really high quality images) compared to images taken with a high quality GEM.The beauty of a GEM is that it's easy to change scopes. On the Mach1GTO, you can carry anything from a small refractor to a 10" RC.You've probably heard this a million times but it's worth repeating... the mount is the foundation on which everything else rides. If you start with a solid, accurate mount, everything else is sooooo much easier. It fades to the background and just works, which lets you focus on the other aspects of imaging. If you spend more money on trying to improve the fork mount, you'll just be wasting money that could be better spent on a real solution.HTH. Just my 2 cents.Best,
Quote:Thanks for the tips. I am also considering a G-11, I think I want a little more room to grow then the GM-8 can offer. Also, my club owns a G-11 that we are considering a Gemini II upgrade on. I would like to play around with Gemini II before I decide, but I think the club is waiting until there is a bit more out there about the new Gemini. That 700-900mm range is what I'm really missing right now. That is really the reason for my desire to get a new mount.

Quote:The AP Pier is VERY stable but takes some breakdown and setp time. It also needs a pretty much level surface to setup on... Joe
Quote:I'm thinking about PWT's Pinnacle portable pier as an alternate to AP's. They look awesome and very portable.
Quote:Speaking of Mach 1 does anyone here have the Eagle Fording Pier designed specifically for this mount?Impressions, comments, stability and anything else about this pier would be appreciated.Vahe
Quote:Quote:The AP Pier is VERY stable but takes some breakdown and setp time. It also needs a pretty much level surface to setup on... Joe That is the one with the cables right? I watched someone setup one and he had a bit of difficulty on an unlevel surface. That may pose a problem.

I lost count of my scopes. Now I just want mobility. I came, I saw, I bought some interesting accessories, and put names to faces: NEAF 2012, ASAE 2012, SWAP 2013, ASAE 2013.

I can't figure out how to level their tripods on a uneven surface. It says it will accommodate up to 4" of uneven ground.

Quote: Really? How about an AP3600? 5 arc-sec peak to peak out of the box - mechanical precision - guaranteed. Add on the firmware PEC and it can easily get into the sub 1.5 arc-sec range or less.
Quote:Hello,Just wanted to mention that I too am intrigued by Rob Miller's tripods..,I've been in touch with him over the past few weeks and am planning on ordering one for my AP mount too.The only thing I'm a little concerned about is the somewhat continuous development on the leveling feet designs.., I did also have a flag over the lack of a "proper" website for pricing and specification data, but I'm aware that he's super busy there - again with design and tripod builds.Will hope to order from the next production run if he's got his designs and product lines set.Which colour scheme(s) did you get for your AP mounts?Regards,skysbd
