Hello Group ,

Thanks to everyone for your input . Uncle Rod , I'm with you , larger circles are better circles . Mike and Roscoe , thanks for giving me insight into the equipment being sent from China today , this is about what I was fishing for . Eddgie and Greg , thanks for the great info on the Super Polaris mount , I have never seen one(in person) but have for years felt(after looking at pic's and reading) it was "the" one small mount to have . As usual from C.N.'s a cascade of usefull information .

All the best , Leonard

You can turn that off by telling the mount it's on a pier. Of course, if you do that and the telescope then hits the tripod I'll deny any responsibility!

As best as I can see, this is not a setting on my LXD 750 hand controller.

Perhaps it was something added in a later version.

Either that or I just don't know where to look.

I had a conversation with someone else about whether or not the LX200 used the same handset as the LXD 750, and based on that converstion, the answer was no. However it is possible (Maybe??) that Meade did what does now with the Autorstar handsets and just allows them to program for either Alt-Az or Polar mode, but like I say, either it was not on my version of hand control, or it is not something I can find.

If you can tell me where to look, I will confirm.

Thanks!

Belay that last, mate. Based on your prompting, I just started scrolling the Telescope option and there it was! I guess I just never looked that far before!

Thanks.. Had you not mentioned it, I may have never known!

Regards.

And by the way. I replaced the factory spreaders with aluminum bar stock (.25" x .5") that was about 3 inches shorter than the stock spreader bars. The result is that it reduced the angle of the legs keeping them in a much smaller footprint. I don't understand why Meade used such a big angle on the legs to begin with.

Also, because I have an adapter to use the Losmandy saddle, the scope sits about an inch higher than with Meade Cradle.

And my scope is shorter than the Meade 6" f/9.

Net result is that I can point 25 minutes PAST East or West of zenith and still not hit the tripod with the focuser housing.

And this used to drive me CRAZY, that the circle of sky denied by the mount was so HUGE.. But now that I think about it, with the standard hugh tripod spread, longer Meade telescope, and lower cradle, it HAD to be a fairly big circle of sky.

Great news for me though is that I am pretty sure that I can leave it in "Pier" setting and never really have to worry about a collision with a leg.

Thanks again!

Cool!

Yes, there's a pretty big chunk of sky unavailable unless "pier" is selected. I think you'll enjoy not having to deal with the warnings (I know I did!).

I know that the "pier" setting issue is already solved, but it occurs to me that this is an opportunity to explain the handbox deal in case anyone else has questions about that. There were a few different handbox revs for the LX200 in the earliest model years. The last one issued was rev 3.21, in 1994 or so. This is NOT the firmware rev in the mount; it's a hardware handbox version that's compatible with the latest mount firmware released. It is this latest handbox version (3.21) that is used with the LXD650/750 mounts, and it is interchangeable for use with later LX200 (1994-2002) models. The feature differences between LX200 models and LXD650/750 models are due to firmware in the mounts.

Yes well remember that the Super Polaris can be used in alt-az mode as well as the Polaris. Few people know that the SP can be used in alt-az mode.
