Comet skyshow - Jan 17

Comet McNaught really became visible around 9pm tonight. This is how it looked then, in the fading dusk. It looked very spectacular through binoculars(I have an old pair of 8x30mm Zeiss glasses).

This is what it looked like about 15 minutes later (narrow apeture and 24 times the exposure length (8 seconds)).

The track of aircraft coming in over our house to land at Adelaide airport took them directly past the comet.

For interest's sake, here's a comparison of the brightness of the comet (left of chimney)and Venus (right of it).
