Monday (10-June-2013) — At Sea

Gone to See Europe. Semester at Sea Spring 2013 Enrichment Voyage on the MV Explorer. Day 45: At Sea between Stockholm and Copenhagen.

Late night or early in the morning (hard to tell this far north when there isn’t much darkness at night) I looked out my cabin window on the MV Explorer and saw the electric blue Noctilucent clouds. I read about them before (http://www.spaceweather.com/), but had never seen them.  The clouds are ice crystals that are very high that you can only see for a short time when the sun is below the horizon. One theory is the crystals are nucleated when micro-meteors pass through the upper atmosphere. We were in the Baltic Sea traveling from Stockholm to Copenhagen and the sun doesn’t set until very late I set up a camera in my cabin and took a set of 99 images that I made into this time-lapsed video (Nikon D4 camera, 28 mm f/1.8 lens (ISO 200, 28 mm, f/1.8, 1 sec)).

Indoor Autumn Nature in New Jersey: Cricket Dance.

A few days ago I noticed a number of crickets in my basement. They are a silent variety as I haven’t heard any chirping. Once I get them identified, I’ll figure out if they are harmful or if I just ignore them. For now they are a good subject for a time-lapsed video. I set up a camera and flash to take an image every 15 seconds overnight.

Six-Years Ago (24-November-2006) — New Jersey

Backyard Vandalism in New Jersey. A Tree in my Backyard Decorated with Toilet Paper.

An interesting night six years ago. I set up my Nikon D200 camera with a 10.5 mm fisheye lens to take wide-angle night sky images from my backyard. I actually put the camera quite a way back from the house, because I wanted to have the camera looking north in my back yard so I could see Polaris (the north star) above the roof of my house. I was still early in a learning mode on how to do night skies and star trails (30 second images + 30 second long exposure noise reduction) once every 2 minutes. I started the exposures beginning about 18:30 H (6:30 PM). The EN-EL3e battery used in the D200 camera had about a 2 hour life, especially when it was cold outside. I had to go out to change the battery every ~ hour. A little after 20:00 H (8:00 PM) I realized that a tree in my back yard had been toilet papered. Going through the images taken by the camera, I could tell when it happened. I am just glad that they didn’t trip over and/or take the camera and tripod. This was reported to the local Montgomery Township police, but nothing ever came of the report.

Backyard Autumn Night Sky in New Jersey: Star Trails and Time-Lapse Video.

Last Night I tried to do some night sky photography. I had to give up after less than 3 hours as clouds moved in. With the images I had I did some star trail images, and a short time-lapsed video including the 15 minute star trail images.

Wednesday (21-December-2011) — South Carolina to Florida

Gone to See America. December 2011 Florida Road Trip. Day 2:  South Carolina to Florida.

I set up a Nikon 1 V1 camera and 10 mm f/2.8 lens on a tripod rigged into the passenger seat, and started driving south. The camera was set to take images every 10 seconds, auto ISO, f/2.8, focus manual (infinity), auto shutter speed. I would have to stop and change the battery every hour or so. The images were then used to produce the following time-lapse video of the road trip.
