Image Size 300 DPI: 22 * 28 cm

Here one sees the stars of the constellation of Orion recorded in an exposure of about 30 minutes, during which time the lens focus was moved from infinity to about 1 metre in a series of 10 steps about three minutes apart. The effect is to reveal the star colours and that of the vivid red Orion nebula.
