Picture of the Day: Sidewalk Astronomy
How cool is this! Spotted at a parking lot in Houston, Texas (Memorial Drive and Dairy Ashford Road) was this guy with a ‘Dobsonian‘ telescope and a sign that reads:
This is a telescope. Come take a look at Jupiter. Free
According to Wikipedia: a Dobsonian telescope is an alt-azimuth mounted Newtonian telescope design popularized by the amateur astronomer John Dobson starting in the 1960s. Dobson’s telescopes featured a simplified mechanical design that was easy to manufacture from readily available components to create a large, portable, low-cost telescope. The design is optimized for visually observing faint deep sky objects such as nebulae.
