Observing Report: Gazing, Grazing & More Gazing!
by Paul Whyte

Saturday October 3 presented us with clear skies, Comet Swift- Tuttle, and a first quarter moon, so I headed over to do some observing at Tony Ward's place. Walter MacDonald also showed up at Tony's and together we observed the comet in Tony's 15" (alias Big Bertha). During the course of our observing, a phone call alerted us to a last minute ephemeris revision for the pi Sgr graze. Immediately we packed up our equipment and, with Tony in the lead, set course for the graze site at trans-warp speed.

Arriving at the appointed place (between Oshawa and Bowmanville) just 15 minutes before graze time, we quickly set up our equipment. A few minutes later Andreas arrived and suggested we move everything about a hundred metres to the north. We did this, with Tony noting that Messier marathon experience is handy in these high pressure situations.

Just moments before the big event, a graze of another kind took place, as a car travelling at highway speeds passed within inches of Andreas' telescope. Needless to say, Andreas immediately moved his 'scope back from the road's edge! As a final impediment, a passing train (about 150m to the south of us) drowned out the sound of Tony's shortwave time signal, but we managed to see the 3.5 minute graze with no further incidents!

After packing up our equipment, we decided to go to Oak Heights to take advantage of the dark skies to be had there after a midnight moonset. The skies were truly fantastic this night! We observed the comet of course, as well as a number of deep-sky objects using Tony's 10x70mm binoculars and Big Bertha. The views of M31 and M33 were unbelievable; M33 was distinctly visible to the naked eye. But the highlights of the night were the views of several sections of the Veil Nebula, and of the entire California Nebula in Big Bertha (with a Lumicon Há filter)! As if this weren't enough, we also saw the California and Swift- Tuttle in binocs!

Though this night could be accurately described as having a sky that just wouldn't quit, Tony and I had to cut it short and head back to civilization, leaving Andreas and Walter to carry on without us. All in all it was a fabulously successful night. If only we could do this every weekend!
