Perhaps Meade is looking at AP mount's ability to track well beyond the meridian...




I saw somewhere that it's specified to go only 20 degrees past. I miss that feature from my old LXD750. The NJP is a terrific mount, but it doesn't know better than to keep driving away even if the telescope's below the mount. I don't see that as an advantage.

At the end of the day is the simple question..... can the design (regardless of the originator) be executed to allow for excellent pointing and tracking? AP took years to perfect their manufacturing tolerances. Bisque also did _not_ have the tracking and pointing they do today when the initial Paramounts were launched. I great idea is the first step. Bringing it to fruition is the trick.

If anyone's still not convinced of where the idea for this mount came from, have a look at this image used by one vendor's preordering system.

Pay attention to the ALT locking mechanism - now where have you seen that before




I opened images of both mounts and compared them closely. By some sort of coincidence (?) there are images from both companies of the two mounts shot at practically identical angles, making comparisons easier.

I must say I am a bit stunned by not only how much the LX 800 resembles the Mach1, but by HOW EXTREMELY CLOSELY the positions of more than several bolt holes, screws and various adjustment knobs match. It's almost a bit uncanny.

At this point I'll go all out and say we're looking at a genuine clone, at least mechanically, though some camouflage has been attempted. I mean, if designing it from the bottom up, how big is the chance that you'll end up with two mounts with not only practically identical overall designs but matching bolt holes as well?

Methinks the reality is that there is some OEM rebranding going on!

AP stepped up production to try to close the waiting list to meet the demand on the Mach 1. There's not a chance they would be making them for Meade as well. you might want to do a little research on the production capabilities before going with the rebranding idea.

Were the initial images of the LX800 CGI drawings as some people have stated? The image of the LX800 prototype now at PATS shown here:

http://www.cloudynights.com/ubbthreads/showflat.php/Cat/0/Number/4812863/page/0/view/collapsed/sb/5/o/all/fpart/1

doesn't look like CGI to me.

I got to touch it, taste it, see it and smell it today at PATS. Went ahead and put a deposit down on it.

Too rich for my blood but the LX80 mount is very interesting. It would be great for my refractor and if the 40 pound payload capacity is correct even my C11 can be used with it. As for the LX800s the f/8 is still slow but I guess that's what the Starlock is for. If Starizona makes Hyperstar lenses for these then that would be a serious wide field imaging package.

I'm visiting the UK and they have the mounts and scopes on-line at Telescopehouse.com. The specs for the larger mount are pretty impressive. Besides being go-to with almost automatice functioning the specs according to the telescopehouse.com site are; "The machined stainless steel and aircraft grade 6061-T6 aluminium construction means that the LX800 is a rock-solid platform. With precision roller bearings on both axes; a 1.75" stainless steel R.A. shaft; 0.68" diameter brass worms and 5.8" diameter, 225-tooth aluminium gears, the LX800 delivers smooth and precise movement. As you would expect, the LX800 is a fully computerised GoTo mount with GPS and comes with a database of over 144,000 objects. All this sets atop a new super-stable tripod.

The StarLock™ module includes two cameras. One camera has a super wide-field optic with LightSwitch style pointing and high-precision mode, capable of landing an object within 1 arc-minute. The other camera, with an 80mm F/5 optic is capable of guiding down to 1 arc-second and is sensitive enough to lock onto 11th magnitude stars automatically! Once the scope lands on a target, it begins to guide itself and all you really need to do is polar align, add a camera, focus, and open the shutter. StarLock even automatically programs periodic error correction also reducing any other errors down to virtually zero. Oh, and they've also included an electronic drift-align assist, which provides a simple routine for accurate polar alignment using the StarLock™ guider to measure the drift. There's no Longer any need for a separate guider or computer and the StarLock requires no user focusing or guide star selection."

From the looks and specs it has only a superfical resemblance to the Mach 1 in that they are both GEQ.

The LX80 easily converts from an AltAz to GEQ and also into a double telescope mount.

That's at least a 45% CO on that scope there... Joe

is it the 10" that is on display? The smaller scopes tend to have larger obstructions, i think the 10" LX200 was already at 38% or so, so i can believe that being a bit over 40%. Too bad its not the 14".

Yes I'd like to see the 14". That did look like a 10". If they have one made how is it the specs aren't out there yet?

I agree. The OTA in the 2nd video has a huge central obstruction. Guess the target consumer will be mostly for imaging, not visual, unless the larger OTAs have less obstruction percent wise.

I see that the 6", 8" and 10" Meade scopes offered with the LX80 mount are standard SCT's, not with the ACF optics. I wonder why Meade wouldn't use the ACF optics as a selling point?

The scope in the videos is the 10" and the secondary obstruction is 20.95 on the 10" 16.86% on the 12" and TBD on the 14".

I have their flyer right here.

BTW one of many things I liked about this mount is that it sits much lower to the ground and the tripod has a very wide stance. Looks really stable with the low center of gravity. The mount weighs 55lbs without counterbar or tripod.

For those who insist on the percentage being expressed in terms of diameter, it's the square root of the percentage by area so you can derive it easily.
