(Up to OJB's 2007-01-18 Observation Page) Observation: More Photos of Comet McNaught
DescriptionThese are some larger versions of the photos I took of Comet McNaught during its recent appearance in the southern sky. These were taken from locations around Dunedin so the sky isn't as dark as I would like, but they give a good idea of what the comet really looked like. In fact, they show a lot more than what could be seen visually. This was taken from Mornington, Dunedin on 2007-01-22 at 22:48:51 NZDST. The exposure was 8 seconds at f/5 using a 40mm lens (35mm equivalent length approx 65 mm) with sensitivity setting of ISO 800. I enhanced this photo using a non-linear contrast adjustment and noise reduction in Photoshop. This was taken from St Kilda, Dunedin on 2007-01-24 at 00:28:09 NZDST. The exposure was 25 seconds at f/3.5 using an 18mm lens (35mm equivalent length approx 28 mm) with sensitivity setting of ISO 800. The comet was over the sea when I took this, so the sky was reasonably dark and the fainter parts of the tail are starting to appear. There was still some very light cloud and light pollution around making it impossible to get any more detail.

The exposure was 30 seconds at f/3.5 using an 18mm lens (35mm equivalent length approx 28 mm) with sensitivity setting of ISO 800. The long exposure picked up the orange glow from street lights which made it difficult to get any more detail in the comet's tail. The other "smudges" in the sky are light cloud.
