Observations made with the 60cm reflector and not previously reported (3)
Continued from the previous report, the following are the
observations made by the 60cm reflector. Many of these are likely numbered
minor planets and known comets. The photograph below shows a method to
discover moving objects by exposing twice on the same frame. It is apparent
that the object is clearly in motion and displays cometary features. I
remember that, many years ago, a person rushed into my home excited about
a "discover" of a comet-like object taking just a single shot.
Even if the object looks fuzzy, a single exposure cannot determine its
identity. It is an iron rule of comet search that a double exposure or
two single shots be made.
