The effect of this is to give a view in which south is down and east and west are reversed. You should avoid using star diagonals and make the drawing the proper way, so that south is at the top. If you insist on using a star diagonal, then the observing form should prominently note this use and indicate north, south, east, and west on the drawing as seen through the star diagonal.

We must remember that a drawing is not a photograph or digital image. It is therefore subjective, being what we perceive with our eyes and our mind, and what we record with our hand. Consequently, as observers we must make an honest attempt to record only what is truly seen, and draw only the amount of detail we can see. We must never record what we think we see or, more importantly, what we want to see or think should have been seen. A dishonest observation will be found out and the integrity of the observer will be destroyed. In science, the loss of integrity is very difficult to restore. Sometimes, it is acceptable to record a feature that is "suspected", and this condition should be prominently noted in the data. In spite of the inability of film to capture fine detail, one of its advantages was that it was an objective, unbiased means of capturing the appearance of the planet. We will discuss the use of film later.

There are two basic types of drawings, a full disk drawing and a strip sketch.
