GUEST,John from Kemsing | BS: Feast of planets. (71* d) | RE: BS: Feast of planets. | 25 Jan 12 |
I attempt to study the heavens with a "SKYWATCHER" (76 mm dia. mirror x 700 mm focal length) telescope. Even using the f10 eyepiece with the Barlow lens, carefully focussed, which should give a magnification of x140 the resulting image seems no bigger than with the naked eye. What can be wrong?. |
