Day 11 and Counting

My Drobo disk-array is rebuilding after adding a new drive. Don’t know how long it will take. New images to follow. The down side to large storage solutions such as Drobo is the time required for backup and restore. Not sure how many days this will take!!!!

My Drobo disk-array is rebuilding after adding a new drive. Don’t know how long it will take. New images (including a meteor caught last night with two cameras) to follow. The down side to large storage solutions such as Drobo is the time required for backup and restore. Not sure if this will be hours or days!!!!

One year ago today I posted an image of the moon taken from my backyard in New Jersey: 19-October-2010

Backyard Autumn Nighttime Sky Over New Jersey.

With a clear sky, and bright waxing gibbous moon I experimented ways to acquire sharp images of the moon through a 600 mm f/4 VR telephoto lens. The lens is mounted on a tripod with a Wimberley gimble tripod head. VR  is turned off, and the camera set for “mirror up” mode. I used a remote release, and let the system stabilize for 30 seconds (time-out for mirror up) before the shutter would be triggered. The first five images are #1 (f/16, 1/50 sec); #2 (f/11, 1/100 sec); #3 (f/8, 1/200 sec); #4 (f/5.6, 1/400 sec); and #5 (f/4, 1/800 sec). I think the best was #4 (f/5.6, 1/400 sec), although all were pretty good. The next two images used a TC-E III 20 teleconverter for an effective focal length of 1200 mm #6 (f/16, 1/50 sec); #7 (f/11, 1/100 sec). Here I think #7 (f/11, 1/100 sec) is best. With the additional magnification, a faster shutter speed is needed to counteract the motion of the moon.

I also made several DSLR videos of the moon, since I was using my Nikon D3s camera body. When I reviewed the videos, I saw that I had captured at least two satellite transits in front of the moon. These transits are less than 1 second long. Subject for another post.

One-Year Ago (25-September-2010) — California

Gone to See California: Point Reyes National Seashore.

I drove out to Point Reyes National Seashore to photograph the Lighthouse. I’ve tried to photograph this lighthouse on several previous occasions, but it was always shrouded in fog. I got there early in the morning, and this time it was very clear. In one image, the moon is above the lighthouse. Remembering my mentor Winston Hall telling us to always look behind you for a better picture, I turned around and saw this buck on a ridge in the early morning sunlight.
