- SETTING CIRCLES (Star hopping is rewarded.)
Observing without setting circles of any kind, earns five (5) points. Mechanical setting circles, if used, net three (3) points. Digital setting circles, if used, get two (2) points. Computerized setting circles that automatically slew to an object, if used, receive one (1) point. Your whole observing run receives the same value. For example, if you use digital setting circles for one observation, then all observations earn only two (2) points, never more.
- LIGHT POLLUTION (Light polluted skies are rewarded.) The square of the difference between 6.0 magnitude and the unaided eye limit for your observing run. If the unaided eye limit is better than 6.0 magnitude, no points are given. If the Moon rises or sets during your observing run, you may use only two different point scores, depending on whether the observation was made before or after Moon rise or Moon set. For example, the limiting magnitude from Livermore on the night of the observing run was 4.3, because the faintest star seen was Theta Cassiopeia; therefore, you have 2.89 points.
- DETECTOR (Use of non-visual detectors is rewarded.) Using the human eye gets one (1) point. A CCD camera provides three (3) points. Photographic emulsion merits five (5) points.
- SITE (Remote observing is rewarded.) Those who observe in their backyards are awarded one (1) point; whereas, those who must drive away from home to observe benefit from two (2) points.
