To orient an object in the viewfinder of the 35mm camera body, use a small jeweler’s screwdriver to slightly loosen three adjustment screws around the outer knurled ring of the
The #62
Photography through a long lens such as the LX200GPS requires special technique for good results, and the photographer should probably expect to waste a roll or two of film in acquiring this technique.
A few tips on photography with the LX200GPS telescopes:
1.Use the Field Tripod for the telescope. At an effective focal length of 2000mm, even small external vibrations can easily ruin an otherwise good photo.
For best results in photographing celestial objects, a wedge and
Caution: With the #62
2.Use a
3.Focus the image with extreme care. While observing the subject through the cam- era’s reflex viewfinder, turn the telescope’s focus knob (6, Fig. 1) to achieve the sharpest possible focus. Note that some 35mm cameras may have an optional focusing screen (available from the manufacturer) for use with a long telephoto lens. This screen provides a brighter and clearer image to focus, and is highly rec- ommended.
4.Correct shutter speeds vary widely, depending on lighting conditions and film used.
Note: The camera used with your telescope may have an exposure meter that is still active when the standard lens is removed and the body is con- nected to the telescope with the
5.Terrestrial photography through the LX200GPS is sensitive to heat waves rising from the Earth’s surface. Long distance photography is best accomplished in the early morning hours before the Earth has had time to build up heat.
6.Photography of the Moon and planets through the LX200GPS can be especially gratifying, but points 1 through 4 should be particularly noted in this case. If you wish to take photographs using polar alignment, see APPENDIX A, page 50.
