After a record-breaking, week-long heat wave, cool and cloudy conditions arrived just in time for Astronomy Day 2010 in Edmonton. Despite this, the RASC Edmonton Centre celebrated astronomy at the TELUS World of Science (TWOSE) from 1:00 PM to about 9:30 PM.
In the afternoon, the RASC booth was front and centre inside the TWOSE lobby and hosted displays about the RASC Edmonton Centre and Light Pollution. The booth was also the hub for the Telescope Clinic in which visitors could have a look at and try out several examples of starter telescopes or try their hand at assembling a refractor telescope. Several people took advantage of RASC member expertise at the Clinic and obtained help in using their own telescope. Perhaps 50 people visited the RASC booth.
Outside, the RASC Observatory on the south lawn of the TWOSE was not very busy throughout the day, due to the cloudy conditions. However, the sun was observed occasionally as it peeked through the clouds. As evening fell, the skies became partly cloudy between advancing fronts, and visitors who were there at the right time had a chance to look at the waxing gibbous Moon (10.5 days old). Mars and Venus were also occasionally viewed. 60-70 people, including a Beaver group on a science sleep-over at the TWOSE, visited the Observatory.
A small Astrophotography Clinic was held in the evening, which demonstrated a prime focus setup on a 10″ Newtonian telescope with a stock DSLR camera. Being the only target visible for extended periods of time, la bella luna was imaged for posterity.
