The Big Eye Candy Mountains

Public star party at Glacier Point, Yosemite National Park

Our tent and telescopes, OSP, Ochoco National Forest, OR

I was inspired to hum this old hobo ballad and change the words a little

recording of Big [...]

Chasing Galileo - 17/18-day old moon

Eighteen-day moon

The moon rises later each evening now. That means a late night for sketchers. Luckily my small 70mm Televue Ranger on a telepod mount requires no setup. I keep it permanently set up in the garage.

The features I’ve sketched on the 18-day moon begin with sunset on Mare Crisium – on the terminator [...]

Chasing Galileo - fourteen-day moon

fourteen-day (full) moon

The full moon rises as the sun sets on the 14th day of the lunar month. A small telescope, such as the 70mm f.8.7 Televue Ranger I’m using for this series of sketches is a perfect instrument for full moon viewing. So are binoculars. The moon is [...]

Map of the constellation Orion

Galileo looked at the fuzzy patch surrounding the head of Orion through a telescope, and resolved many starts not previously known. He called it Nebulosa Orionis.

Look between the shoulder stars Betelgeuse and [...]
