RASC February Meeting
Friday 20th March 2015
7:30 p.m. to 9:00 p.m.
Dr. David Turner
The Eyes are Still Good Detectors
While new detectors have had a positive effect on the precision of observations by amateur and professional observers, and have made it easier to acquire high quality images of astronomical objects, such progress often overlooks the power and precision of simple eye estimates, which are useful in many situations. Described is evidence for the high precision of eye estimates of brightness when conditions warrant them, as well as a variety of techniques that make visual photometry easier and more reliable than is sometimes the case. Examples are presented of stars for which CCD or photoelectric observations can be problematic, and visual observations would be beneficial, in some cases for scientific offshoots. All, of course, can be found in the Observerís Handbook.

About Monthly Meetings
Regular meetings open to everyone. Note that we have recently changed meeting rooms! They are held at Saint Mary's University in Room AT101 (Atrium Building). Meetings are held monthly (except July and August) beginning at 8:00 PM, normally on the third Friday.
A typical meeting consists of one or more feature talks. The main talks cover a variety of topics ranging from astronomical stamps to the latest advances in the space sciences. Shorter talks also cover a variety of topics such as: "what's up in the current sky", the latest astrophotographs by club members, or the unveiling of a new telescope.
Observing Night at Saint Croix Observatory
Members may be found observing at the Saint Croix Observatory on almost every clear, dark night. Once a month, we encourage members and their guests to congregate at SCO, at which time new members are particularly welcome. Upcoming Observing Nights are:
