Primary Mirror Adjustments If the secondary mirror and the reflection of the primary mirror (1), Fig. 8, appear centered within the drawtube (2), Fig. 8, but the reflection of your eye (3), Fig. 8, appears off-center, one or more of the three primary mirror hex screws of the primary mirror cell will need to be adjusted.
- 8 - Most observers will want to have 3 or 4 eyepieces and perhaps the #140 2x Barlow Lens to achieve the full range of reasonable magnifications. See OPTIONAL ACCESSORIES , page 11, for further details. ASTRONOMICAL OBSERVING The Starfinder telescope is an excellent observing tool for the ser io us am at eur a st rono mer.
-9- circles with the Celestial Pole at the center. By lining up the telescope's polar axis with the North Celestial Pole (or South Celes tial Pole if obs erving from the Ear th's Sou thern Hemisphere), celestial objects may be followed (tracked) by moving the telescope about one axis, the polar axis.
- 10 - 6. Remove the jumper from one prong and slide it onto both prongs. The telescope will now track in an easterly direction for southern hemisphere operations. 7. T o return the telescope to northern hemisphere operations, pull the jumper off both prongs and store it on one of the prongs.
4 . Use "fas t" f ilms (high A S A r atings) to re duce exp osure t i m e s . 5. Focus the image with extreme care. While observing the celestial object through the camera's viewfinder, turn the telescope's focus knob to achieve the sharpest possible focus.
