Silhouette of a Jet Transiting the Sun.

Today, while looking at the sunspots (we are at or near the solar maximum) I captured an image of a jet transiting the sun. This was with a Stellina automated telescope fitted with a solar filter.

Cold Winter Night Sky.

The forecast for the night was mostly clear. The waxing gibbous moon is getting brighter (69% illuminated). For the first of the night, I programed the “Plan my Night” sequence on the Vespera telescopes to first observe the moon, then later as the moon moves to the west picked some deep sky observation targets in parts of the sky away from the moon. I also set up a Nikon D9 camera with a 8-15 mm fisheye lens to take a sequence of images of the night sky with the full Vespera family of telescopes in the foreground. These images were then used to create the following time-lapse video. The moon is the bright object. You can watch the Orion constellation travel across the sky. Lots of jet trails, a few passing clouds, and a couple of meteors. Best viewed in the dark and expanded to full scale. Images captured by the telescopes to follow.

Trolls out for the Snow

We didn’t get much snow. Mostly the winter weather was further south, frustrating January 6th protestors in Washington, D.C. In the following time-lapse video, let me know how many birds you can identify, and how many deer you can see in the far background. The deer are outside of the deer fence.

Silhouettes of Jets Transiting the Sun.

Today, I captured images of jets with condensation trails transiting the sun while looking at the sunspots (we are at or near the solar maximum). I was viewing the sun with a Vespera Classic and Stellina automated telescope using solar filters. For much of the day there were high level clouds partially obscuring the sun. I’m not sure why the solar images from the Vespera Classic telescope have a dark green background. The image from the Stellina telescope has a normal black background. There is a difference in the displayed angle of the sun between the Stellina and Vespera telescopes. Compare the position of the sunspots.

Nine-Years Ago Today. Seagull with the MV World Odyssey docked at the San Diego Harbor. One day before the 2016 Spring Semester at Sea Voyage would sail. (04-Jan-2016, California).

Red Fox in the Backyard Hunting

Just before this video, a rabbit was observed running away. After I mowed down the wildflower meadow, the field is pretty barren.

Wintertime Nature in New Jersey.

No Birds of the day in my backyard today. So I have included one from six-years ago today of a Whiskered Tern at the mouth of the Yangon River in Burma.
