After nearly two months of rain, rain, and cloudy skies — we finally have been able to see the sun and very blue skies. At night, I’ve taken the opportunity to get night sky images, as well as lunar images through some of my exotic 300, 400, 500, and 600 mm lenses. One of the problems I was having for the overnight time-lapsed images was that the lens would get covered by condensation during the night and ruin the night sky images. ARRG! As the weekend progressed, the temperature rose and the relative humidity decreased. I finally got a full night image set with limited problems with condensation. The first time-lapse video and star trail was recorded with a Nikon D3x camera and 14-24 mm f/2.8 lens @ 14 mm. There was a bit of condensation that affected the end of the video from this lens. The second time-lapse video and star trail image was recorded with a Nikon D3 camera and 16 mm f/2.8 fisheye lens looking north from my deck.
Lessons learned: 1) I need to look into a resistive heater to keep the lenses warm enough to prevent condensation. 2) I didn’t know that the 14-24 mm lens would creep if pointed straight up — during one night the focal length changed from 14 to 18 mm. For the last night, I used Gaffer tape to fix the focal length of the lens at 14 mm. 3) My tripod/heads are not strong enough to prevent movement when I change batteries. Look into an external power supply and not batteries for long overnight image session.
I saw this flock of Turkey Vultures warming themselves in the early morning sun. The local Turkey Vulture population has increased over the past several years. I think their major food source is deer killed by automobiles.
Gone to See America October 2008 Road Trip. Eighth Annual Nikonian Photography Adventure Trip. Day 5: Yosemite National Park.
The Park Service recovered all of our belongings from the tent-cabins in Curry Village. We then checked into various Yosemite hotels and lodges (gratis). Much higher end lodging than the sparse tent-cabins. Before dinner, Michael Mariant as a special treat after all the weeks commotion took us for a walk along a quiet and peaceful section of the Merced river. The diffuse and sublime lighting made for some great images.
