| The Crab Nebula imaged with my Meade LX200 10"
at F/4 and a CB 245 CCD Camera. This image is one 6 minute exposure and
was taken from my backyard near Laguna Beach, Calif on Feburary 5, 1997.
The Crab Nebula is believed to be the Supernova of 1054 AD and was called
the "guest star" by the Chinese. The Chinese observed this "guest
star" for 23 DAYLIGHT days, and for a total of 24 months of
night time observing. The Crab nebula is expanding at a rate of nearly
600 miles per second (50 million miles per day). This rate of expansion
is fast enough that Astronomers are able to see changes in the nebulas
structure over relativly short periods of time. |
