If it weren't for physics and law enforcement, I'd be unstoppable.
Quote:Ed:I presume you want to use the MT solely for visual use, correct? As a visual platform, I have found it to be highly portable, very accurate (for both GoTos and tracking), and easy to set up. Buy it from Steve Forbes at Trapezium and he'll test it before it ships. I would not recommend the MT as an imaging platform.

Quote:Thanks for the reply! Yes solely for visual. And Trapezium in definitely on the short list! Well that's one pro.... any cons anyone?TIAEd
Quote:Ahem! It is a great imaging platform! I have imaged with it in alt/az for about 7 months with good results. I now get longer exposures in EQ mode mounted on a wedge. I autoguide it with an Orion StarShoot DSCI II camera through an ST80 piggybacked on top of my C8/Hyperstar3/QHY8 OSC AP setup. Here is a picture of M8 and M20 from a stack of 11 subs shot at 120 seconds exposure on 6/30/09John Bozeman
Quote:I was seriously considering the MT also, but was totally turned off by two things I heard/read about.1. One owner reported that the battery cord wrapped around the mount after locating many objects, the problem being that the mount head would almost always turn clock-wise when locating an object instead of going left and right.Has THIS been FIXED!2. The legs don't appear to be sturdy enough. Got it from a very reputable source that the mount suffers from the "jiggles".So, for these TWO reasons have not gotten this mount. Can anyone confirm or refute or explain that these are minor and/or have been fixed? Especially the "cord wrap" thing.I was even thinking of placing this mount on my AT Voyager, which is a very solid A/Z platform. I am getting real tired of having to "re-engineer" telescope stuff I buy 10 seconds after I unpack it.Thanks.
Quote:Where the MT really shines is in doing what it was originally designed to do, namely, provide a great grab and go mount that tracks really well.
Quote:I had one and returned it after about a week. A bunch of small design and construction issues turned me off.First of all, I had to jiggle the antenna wire for the GPS unit to get it to work. Even after it started working, it could take 10 minutes to get a GPS lock. Given the large number of GPS problems, this aspect of the design was clearly under-engineered.Set-up and alignment was pretty easy and gotos were very accurate. But is was definitely more jiggly with my 100mm f/9 refractor as compared to my William Optics EZTouch. It was more of a low frequency wobble rather than a higher frequency jiggle, so it didn't interfere with focusing. (I traced the vibration to the azimuth bearing.) It was disappointing to get this level of shake with a 12 lbs scope on a mount rated for 25 lbs.Some construction issues: the battery compartment was not properly sized. The only way to get the battery holder out of the compartment (in order to load batteries) was to extract it with a long-nose pliers. While the mount was mostly metal, the plastic trim on the head around the battery compartment seemed rather cheap-looking. On the tripod, the little screws that hold the flange that separates the upper and lower leg sections were too long and they caused the legs to jam if they were tight. I added small fiberboard washers to the three screws to fix the problem. But this level of careless engineering and/or assembly was disappointing in an $800 product.Finally, when using the mount, there was a clear vibration at medium and high power when tracking objects. Some vibration in the motor/gear assembly was being transmitted to the telescope. I supposed I could start fiddling with backlash settings and the like, but I decided that this thing was simply not a finished product. It just felt like it wasn't going to last, and I didn't want to spend $800 on something that seems poorly made and likely to fail after a few years. So after one week it was returned to the store for credit.
Quote:GPS does not work, even after checking for loose wires.There is slippage on the alt knob. go/tos are not anywhere near the center of a 24mm ep.once you put on the telescope it is nearly impossible to get the mount level using the in-built bubble.I would not recommend this mount
Quote:I've had mine for about 6 months. It works great! I use it for a TMB 92 and a Celestron 6" SCT. When I 1st got the mount, I looked at the GPS to make sure all things were connected. They were. The unit has a hatch with 4 screws for the GPS so you are not taking it apart.As others have mentioned...it's accurate. How are the legs? Well, it's not my CGE but then again I have use of my back for the night. It's not a heavy duty mount. It is a GREAT portable mount that gets you observing quickly. It does exactly what I expected from it. It allows my to look at things without having to make adjustments every 20 seconds or so.Do I have complaints? Well, every mount has an 'issue' and that includes the most expensive ones. If you look at the forums some are 'too heavy' or 'too tall' or 'cables are bad' or 'building it in the dark problem.' It's a portable mount that implies it's light weight. Electronics work for me well. The legs are great for a portable mount. I like the system used for leveling it...very smart. Would I buy again? Yes. It fits my needs 100%

Quote:I think it's a *BLEEP* shoot. I had one for a couple of weeks and just returned it. I'm getting an Orion Sirius GEM instead. Most of the problems I had with mine were related to poor tracking and intermittent motor operation and slewing in azimuth mode. Sometimes it would just stop functioning all together. I installed the latest firmware upgrades and they made no difference. All in all, I think the Mini Tower was a good idea but poorly engineered. Qc also seems to be questionable give the number of problems people seem to be having. Not recommended.Jim
Quote:Ask and you shall receive! Here's a 127 F8 on the MT, It worked, but I think the scope is a little long for the MT. I think the MT will handle a 100mm just fine.Bob
Quote:I ordered one from Trapezium last week with Steve's ultra bearing upgrade and a 6" round tripod adapter plate to mount it to any 3/8-16 flat top tripod. He says he's at about a three week turnaround right now so I won't have it for a few weeks but I'll let y'all know how that goes.
Quote:Although I don't think I could afford the Trapezium tune up. I hope it works out for you!
Quote:Hmmmm glad I started this thread. I think I will be avoiding the MT. I am just a beginner and need to follow a path of least resistance. I want a cheap GoTo for visual but I don't have the time nor the resources to tinker with unreliable equipment. So I guess my search continues.....
Is there a good cheap grab and go goto for a 100ED F/9 out there somewhere????
