Dedicated to the Advancement of Astronomy and Allied Sciences

The Halifax Centre of the RASC is an active association of over 200 amateur and professional astronomers, united by their appreciation of the night sky and the wonders it contains. The Centre is located in the provincial capital city of Halifax, Nova Scotia, Canada, but many members live in several outlying communities, other provinces, and even other countries. The roots of the Centre date back to 1951 when, with the help of Father Burke-Gaffney of St. Mary's University, the Nova Scotia Astronomical Society was founded. The NSAS became the Halifax Centre of the RASC in January 1955. The RASC prides itself in educating the general public about astronomy. The public programs sponsored by Halifax Centre include: lectures, public star nights, and activities during special astronomical events.

RASC February Meeting

Friday 20th March 2015

7:30 p.m. to 9:00 p.m.

Speaker 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.
