David's Images of the Day Photoblog
When going to mail a letter today, I noticed that the Purple Crocuses were in bloom along a south-facing rock wall. Early, but not as early as last year 17-February-2012. Last year I used the Nikon 1 V1 camera, this year the new Nikon 1 V2 camera. This is the first time I used the 60 mm f/2.8 macro lens (with the FT1 adapter) with a Nikon 1 camera.
Turkey Vulture and the Moon. Image taken with a Nikon D2xs camera and 80-400 mm VR lens (ISO 100, 400 mm, f/5.6, 1/200 sec).
I attached a 600 mm f/4 VR lens to the Nikon 1 V2 camera using the FT1 adapter. This was then set up on a tripod with a Gimble head on my back deck. Because of the small size of the digital sensor on the N1V2, this combination has a field of view (FOV) equivalent to a 1620 mm lens on a full size (35 mm) digital sensor. I wanted to see what type of images I could get, especially of small birds. There is more noise with the small sensor (and I think more noise with the N1V2 than the N1V1).
I caught this white-throated sparrow eating a red berry in my backyard. The Nikon 80-400 mm VR lens is probably my most used lens. It is light enough to be hand held, and gives the reach to get images of small birds.
The sky was clear Thursday night. I had three cameras out to capture Geminid meteor trails. Friday night the sky was also clear, so stayed up again to capture any late Geminid meteor trails. After being up two nights in a row, I really needed to catch up on some sleep. When I started to review the images today, I found an anomaly in the star trail image between 2-3 AM Friday morning. The images for this composite were taken on a Nikon D4 with a 14-24 f/2.8 lens. I have trouble with condensation on this lens and this night was no different and because it was cold frost formed on the center on the lens. The result is that light getting to the center of the image is significantly attenuated. I didn’t expect to see anything in the center area because of the frost — but there was one bright star. The unusual star is actually brighter than Sirius. I went back and reviewed the individual images, and found that this “star” only appeared at 02:19 AM — not before and not after. I checked the images from the other two cameras. The D800 with a 16 mm f/2.8 fisheye lens covered the same space, and indeed it also captured the same anomaly. I didn’t see any news about a super-nova, so did I capture an image of a Geminid meteor coming right at me? Good thing that they burn up in the atmosphere!!
