Observers' Forum

Using a Barlow lens and focal reducer by Maurice Gavin.
A telescope's fixed focal length and image scale cannot satisfy all conditions particularly when capturing images onto film or CCD. These images taken with a Meade LX200 SCT, show the application of the Barlow lens to increase the focal length to reveal fine detail, and a focal reducer (FR) to increase sky coverage.
