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.

Backyard Summertime Night Sky Over New Jersey.

Perseid Meteor Shower. Conditions for viewing the Perseid Meteors this year were not good. The moon was full with relatively high humidity and some clouds. I set two cameras up to take images overnight, and got maybe three images of meteors. I’ve made a time-lapse movie from the two image sets.

As a side note, I am running out of hard disk space. I could get another WD My Book external drive, but have run out of USB and Firewire ports on my computer. I’m thinking about a Dobro disk array. What ever I do, I also need to maintain an off-site backup copy. I worry about some of the cloud options, both due to cost and the fact that ATT limits me to 5 GB/month of broadband internet access.

Backyard Summertime Night Sky Over New Jersey.

Multi-Exposure View of the Waxing Gibbous Moon. I went out last night to see about setting up a camera to do some star trails and possibly catch some Perseid meteor trails. I gave up because of the bright  waxing gibbous moon (90% illuminated) and some fast-moving clouds. After midnight, it did clear up long enough to get this multi-exposure view of the moon. I set it up for 2 minutes between exposure. I think I need to go to 2.5 minutes for no overlap for a full moon.

Backyard Summertime Night Sky Over New Jersey.

Multi-Exposure Waxing Gibbous Moon — Going Up, Going Down.  A ten exposure image of the waxing gibbous moon going up or down using the in camera multi-exposure function. The exposure times were varied in 1/3 EV increments (1/1000, 1/800, 1/640, 1/500, 1/400, 1/320, 1/250, 1/200, 1/160, 1/125, second). The exposures were taken every 30 seconds and used mirror up to minimize camera/lens vibration.
