Aperture:f/4
Focal Length:16mm
ISO:400
Shutter:15 sec
Camera:Canon EOS 5D Mark II

Earlier this week I shot a similar scene with the Moon in the photo, when it was near Jupiter. This is the same sky but 5 days later, on January 26, with the Moon now out of the picture, but serving to light up the landscape.

This is the old house on my property that serves as an occasional foreground for test nightscapes. In this case, I was testing my veteran Canon 5D MkII camera against a new Canon 6D. This shot with the 5D MkII had the best arrangement of clouds and stars and works as a decent enough shot on its own.

You can see Orion dodging the clouds, with Sirius at left, and Aldebaran, Jupiter and the Pleiades at upper right.

So what of the tests? Initial impressions are that as far as noise is concerned (always the bane of astrophotographers) the new full-frame Canon 6D improves upon the 5-year old Canon 5D MkII by a factor of two. Noise looks to be about one f-stop better in the 6D, no doubt due to its new Digic V on-board processor.

What this means is:

• Images taken with the 6D at ISO 6400 have a similar level of noise as do images taken at ISO 3200 with the 5D MkII. ISO 3200 images with the 6D look like ISO 1600 images with the 5D MkII, and so on.

• So, if you were happy with shooting at ISO 1600 with the 5D MkII before, you could now shoot at ISO 3200 with the new 6D and get similar results, but with the added benefit of being able to cut your exposure times in half, always a nice thing to do.

• Or conversely, you could continue to shoot with the Canon 6D at ISO 1600 for the same exposure times as before but get shots with much less noise in them. Always a good thing, too!

It’s great to see camera state-of-the-art advancing.
