Quote:I'm not actually interested in buying one, just looking for some info. Curious, I guess. I mean ones that aren't specially made for you as well.
Quote:How large is your wallet? Companies like DFM Engineering will build you as big a scope as you (or more likely an institution) can afford, e.g., DFM's "Standard Classical Cassegrain" offerings which include "50" - 1.3M CCT and larger" models. APM have shipped triplet refractors with apertures of at least 12" and the 3RF have a D&G (achromatic) refractor of 15" aperture.
4.5", 6", and 10" Newtonian astrographs.
2 ST80s; ED80; 3 CCD cameras; 5 EQ mounts: all polished, tuned, and modified.
The rule of telescope features: aperture; equatorial tracking; or low cost. Pick any two.
Quote:I know that's what they do with radio telescopes, so I don't see why you couldn't do it with a slightly higher spectrum, I guess...
Quote:Yeah... I wonder If you could make it so that instead of the light coming out of each eyepiece, it gets reflected somehow into a central scope or something...

Quote:The op doesn't WANT one made. Just wondering what the largest marketed scope in different categories are. Kinda curious myself now! I do recall a thread with pics of a man, his father and brother unloading his scope. A forklift was used for the mirror and cell. It was 500 pounds (the mirror) crate included. I don't remember where, but will try to find it.
Quote:Hey Everyone,Does anyone know the biggest of each types of telescope you can actually buy?I'm pretty sure the Orion 50" Dob is the biggest Dob, and the Meade 20" is the biggest Cassegrain, but can anyone tell me any other telescopes that are bigger? Refractors, Dobs, Schmidt-Cassegrains?Louis

I think it is clearing up!

As others have pointed out, they were vaporware.. a webpage, a dream and nothing more.One does not want to think about the largest Cassegrain you can actually buy.. it's just a question of how much you can afford. APM on Astromart If one needs a bigger scope than 80 inches, they are out there.Jon
Quote:Okay here is stupid question time:Instead of one huge 50" mirror why not just have four precisely aligned 20" telescopes like an inteferometer? Use a Mallincam or other high res camera for viewing. Link them together in a network. You would effectively have more aperture than one 50" telescope. Your complexity would be in synchronizing the telescopes together but with modern high resolution mounts it seems like it would be relatively easy. Has anyone done this before at home?obin
