Silhouettes of Objects Passing in Front of the Sun.

Today, I captured images of a jet with a condensation trail and a bird 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 telescope fitted with a solar filter. The exposure time for solar observations with the Vespera Classic telescope is 250 microseconds (1/4000 sec). The Vespera Classic takes ~51 solar images per minute. Over an hour that amounts to 0.765 seconds (or 0.02% of the time).

Comet C/2023 A3 (Tsuchinshan–ATLAS)

The comet is getting fainter and the tail much shorter. You may need to look closely, the comet is in the center of the frame. The magnitude is now 10.5. The first image is a composite of 32 images (5 min 20 sec) and the second one is a composite of 128 images (21 min 20 sec). In the second image there is some movement of the comet head.

Silhouettes of an Airplane, Jets, and a Turkey Vulture Transiting the Sun.

Today, I captured images of an airplane, two jets, and a Turkey Vulture 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 Vespera Pro automated telescope using solar filters.

Note I am guessing it is a Turkey Vulture. It could also be a Black Vulture. Image taken with a Vaonis Vespera Classic Telescope (200 mm, f/4, 1/4000 sec) with a solar filter.

Silhouettes of Jets and Geese Transiting the Sun.

Today, I captured images of a flock of geese and several jets 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 Vespera Pro automated telescope using solar filters.

Six-Years Ago Today. Pillar of Light at Sunrise. Composite of 6 images taken with a Leica CL camera. (08-Dec-2018, New Jersey).

Comet C/2023 A3 (Tsuchinshan–ATLAS)

The comet is getting fainter and the tail much shorter. The magnitude is now 10.1. The first image is a composite of 31 images (5 min 10 sec) and the second one is a composite of 254 images (42 min 20 sec). In the second image there is some movement of the comet head. Also, the comet is moving into a region of the sky with part of the milky way in the background (many more faint stars).

Nine-Years Ago Today. Frost covered Common Barberry. Hobler Park, New Jersey. (06-Dec-2015).

Jet Silhouettes Transiting the Sun.

In addition to the sunspots (we are at or near the solar maximum) I captured two jets transiting the sun using a Vespera Pro telescope fitted with a solar filter.

Comet C/2023 A3 (Tsuchinshan–ATLAS)

The comet is getting fainter and the tail shorter. The magnitude is now 10.0. The first image is a composite of 31 images (5 min 10 sec) and the second one is a composite of 90 images (15 min). In the second image there is some movement of the comet head. Also, the comet is moving into a region of the sky with part of the milky way in the background (many more faint stars).
