One-Year Ago (19-May-2016) — New Jersey

Backyard spring nature in New Jersey. A Chipping Sparrow, a Carpenter Bee in flight, a cluster of Rhododendron flowers, a white wildflower, a Jack in the Pulpit flower, and a ball of Dandelion seeds. I ended the day taking some pictures of the Waxing Gibbous (nearly full) Moon. All but the chipping sparrow image were taken using a Fuji 100-400 mm OIS lens. I am really liking this lens as an alternative for the Fuji X series cameras to the Nikon 80-400 mm VRII lens. The Fuji 100-400 mm lens is about the same size as the Nikon 80-400 mm lens. Also, since the sensor on the Fuji X cameras is 1.5x smaller than a full frame 35 mm sensor — the field of view for the Fuji 100-400 mm lens is equivalent to a 150-600 mm lens.

Backyard Astronomy in New Jersey: Sun and Moon

The sky was clear so I took my telescope out. First to see the big sunspot (AR 1339), and then later the waxing gibbous moon. The Questar telescope comes with a solar filter to safely view the sun and sunspots.

Multi-Exposure Waxing Gibbous Moon — Going Up, Going Down.

A 10 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.
