The Galileoscope is Coming!

The Galileoscope is coming!  This is a cornerstone project for the International Year of Astronomy (and, in the interest galileoscope_logo1of disclosure, one I work on).  The Galileoscope is a small, low cost, high optical quality telescope that anyone can build and recreate many of Galileo’s famous observations.  You can see craters on the Moon, the phases of Venus, the Galilean Moons of Jupiter and the rings of Saturn.

The telescope has a 50mm achromat lens with a 20mm eyepiece yielding a magnification of 25x and a nice big 1.5 degree field of view.  A supplied 2x barlow lens can bump the magnification fo 50x.  As an added bonus, you can use the Barlow lens as an eyepiece to construct a true Galilean telescope and see what Galileo had to work with (Galileo used a diverging lens for his eyepiece which is not the ideal configuration…and you can see why!)  Or you can insert your own eyepiece as the holder accepts any standard 1.25″ eyepeice.  The included nut allows you to mount the telescope on any standard camera tripod.  I posted a previous blog entry on my attempts at imaging with a Galileoscope.

The assembly is simple and requires no tools.  The telescope can be put together and taken apart easily multiple times.

There are free educational materials available on the web site covering how telescopes work as well as how to osberve with the Galileoscope.

The Galileoscopes cost $15 plus shipping ($12.50 each if you order 100 or more, say for a school, astronomy club, or just get everyone on the block together to order them).  I have been talking to a lot of people at meetings and there are some college professors who are making this a madatory item for their students in the fall.

When you order a Galileoscope, you have the option to donate one or more to underserved students around the world.

Sorry if this sounds like a commercial.  A lot of people have worked hard and put a lot of time into its development and I want to see a LOT of Galieoscopes out there!

Now back to your regularly scheduled programming.
