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.

Some cS forum members are keen amateur astronomers and I wanted to point out my telescopes blog with photos taken at some of the 160 observatories I have visited so far.

My dad and I were into astronomy in my teen years up through college. We had a 10" Dob that was a major pain in the you-know-what to transport around. I can't imagine the logistics involved to move this fella's 900 pound monster.

Now that my father is retired and living next door to my family, he, my son, and I are planning on getting a crash course in modern amateur astronomy and "get back into it."
