Seven-Years Ago (28-August-2012) — North Atlantic Ocean

Gone to see Europe. Semester at Sea. Fall 2012 Semester Voyage on the MV Explorer. Day 06: At Sea, North Atlantic Ocean.

It was another rough night with heavy seas. I got a picture of the waves outside my cabin portal. By dawn all of the water in the pool had sloshed out and the deck chairs were all tied down. During the day the wind reduced and the seas had calmed. By early evening the happy students escaping from cabin fever were out on deck for sunset. While shooting sunset, I looked behind and saw some students on the upper deck with the waxing Gibbous Moon in the sky next to them. I would watch out for this type of moon shot on subsequent Semester at Sea voyages. I am waiting for a camera and telephoto lens combination where both the people and moon are in focus (infinite depth of field, and infinite ISO, with no noise).

Twelve-Years Ago (28-August-2007) — Colorado

Summertime Night Sky Over Colorado.

There was a partial Lunar Eclipse while I was working at the Merck/Sirna site in Boulder. The sky was clear and I spent much of the night observing the eclipse from the Sirna parking lot. At one point I must have stood in front of the camera for a selfie.

Three-Years Ago (27-August-2016) — New Jersey

Backyard Summertime Night Sky Over New Jersey.

Star and jet trails plus clouds. Images taken with a Nikon D810a camera and 14-24 mm f/2.8 lens (ISO 200, 14 mm, f/4, 120 sec). Raw images processed with Capture One Pro, and the composite generated with Photoshop CC (statistics, maximum). One problem I continue to have is moisture condensing on the lens as temperature cool over the night. Especially with wide angle lenses with lots of glass surface area. You can see how the condensation blurs things in the final image. I’ve read about adding electrical resistance thermal tape to heat the lens, but worry about damage and optical artifacts. I’ve also added a time-lapse video of the night sky show.

Seven-Years Ago (27-August-2012) — North Atlantic Ocean

Gone to see Europe. Semester at Sea. Fall 2012 Semester Voyage on the MV Explorer. Day 05: At Sea, North Atlantic Ocean.

The day was a bit rough as we crossed the North Atlantic. Splash from the waves made it up to the portal in my cabin on deck 5 of the MV Explorer. Image taken with a Leica X2 camera (ISO 100, 24 mm, f/5, 1/320 sec).
I didn’t get sea sick, but there were not many of the students or staff that showed up for lunch or dinner. Most of the decks were off limits due to the heavy seas and winds. In the early evening I was able to set up a camera in a protected area to capture the sun going down for a time-lapse video.
