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 (79% 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, and almost no clouds. Best viewed in the dark and expanded to full scale. Images captured by the telescopes to follow.
