I was out today running errands and stopped by Home Depot to get some non-magnetic hardware for my LX5 field tripod. The problem was the stop nut for the...
Cliff, Other than magnetism messing with a compass, will it mess with a telescope at all? I know mine is plastic, aluminum, and hopefully some glass for ...
A 12-inch LX-200 classic with gross mirror flop (5 - 7 arc minutes!). What to do? Take it apart and repair the mechanical shortcomings. And there are plenty...
I do not recommend this procedure and had indicated such to Tom prior to this; first of all there are no carbon fiber tubes available for the Meade diameter...
Mike: It would take a major magnetice field to "mess" with the scope, so I wouldn't sweat it. My daily ride is a Luxury Rich Red 2003 100th Anniversary...
... Interesting statement. You have knowledge of all, repeat, all carbon tube makers in the US...and know what they can, and can't make? I'm speaking to one...
Congrats.... I will also do your taxes if you like. I still do not recommend this procedure for the average LX200 owner. Dr. Clay _____ Arkansas Sky...
... planning to do and there is a lot of truth to the old saying "if it ain't broke, don't fix it." Mirror flop of 5 - 7 arc minutes. When changing focus...
... No, thanks. Only suckers take that kind of offer. ... I don't either, but I'll keep making info available so that users can make up their own minds...and...
How about not making any of this personal, Tom? I simply suggested that this is not a project for the unskilled..... Please lighten up. I am very glad that...
... Help folks get rid of the pig iron ring. Many scopes cross your workshop tables. You know the truth. Most scope users don't. Don't hide the truth. Tell...
If you are interested in making your own tube for a 12-inch LX-200 classic (to replace that high-expansion aluminum one): Tube ID: 13 3/8 inches Tube length:...
... Probably. I had never heard of this weight in the 12", but they did the same on the 7" Maks, probably because they used most of the same mechanical parts...
More photos and text at <http://tech.groups.yahoo.com/group/Meade-Uncensored/files/LX200-OTA-disassembly/> Today's results: Removing the useless iron ring....
... The spring is following the pig iron ring into the trash bin. (But maybe I can use that iron ring as a door stop...so I may keep it.) I will clamp the...
The motion of a main mirror in most SCT designs for focusing is about 50 times more effective than an external focuser's motion. So freezing the main mirror...
... about 50 times more effective than an external focuser's motion. So freezing the main mirror in position may lead to an inability of certain accessories...
... What say you about a scope with 5 - 7 arc minutes of mirror flop? How effective is that? Or am I simply supposed to tolerate that horrible performance? --...
One big reason why the mirror flops...the measured gap (after removing that thick, nasty grease) between baffle tube OD and mirror cell ID is a whopping 0.005...
... 5th would be about right if you wanted to use gooey grease I would think. ... Is this a valid test? there is no reason why the back of the mirror should...
... Fascinating. :-) Your daily reports are very interesting and I wish you success with your project. Out of pure curiosity, I Googled "tolerance of automatic...
... Gooey grease is not how you hold an object in place (especially to the tolerances we need to maintain collimation, keep focus, etc.). Gooey grease (or...
... Depends on the product, auto transmissions are often described as high precision but they are fairly run of the mill as such things go. The bright silver...
... An automatic transmission is subjected to static and dynamic loads, temperature extremes, and speeds...that would destroy a telescope. Often, tolerances...
... Amazing, isn't it? We can easily find many examples of extremely close-tolerance parts being made in gargantuan mass-production facilities. It begs the...
... It's all about cost and profit margins. You could make things to very fine tolerances, but the time involved would raise the cost to such a high amount...
... No, I was visualising that you had the mirror pointing up and bouncing the laser off the front onto the ceiling. You then rotate the mirror around the...
... The baffle tube OD and mirror cell ID are machined. They (except for that horrendous 0.005 inch gap) define a fairly accurate axis about which the mirror...
