Dobsonian telescope with a 1.77 m mirror:
A Utah man has set a record by building the world's largest amateur telescope, and he plans to travel the country to allow others to use it.

By day, Mike Clements drives a truck to Idaho and back. However, by night, he's preoccupied with something much less down-to-earth.

Clements is an amateur astronomer who, after years of planning, finished constructing the world's largest amateur telescope in September. The telescope is as long as a school bus, and weighs about 900 pounds. It also houses a mirror that is 70 inches wide.

I can't wait until he brings it around to my neck of the woods for a little peek!

The article didn't say what kind of optical system it's configured as. Couldn't really see anything that looked like the eyepiece holder in any of the photos.

I wonder how much constantly transporting that scope will throw the focus out of whack.

The size itself is noteworthy but the owner basically just erected Newtonian scaffolding around some glass he purchased rather then grinding the primary.

That's correct but getting this 1.7m mirror aluminized and collimating the optics of this huge telescope must have been some work.

I knew there are several amateur-astronomers among collectSPACE forum members... all ready for Comet ISON.

All times are CT (US)
