Birds and planes passing in front of the sun with sunspots
Today it was silhouettes of a turkey vulture, some other birds, and partial silhouettes of a jet and a small plane passing in front of the sun. I’ve also added the time-lapse video if you want to look for other objects passing in front of the sun. There are several sunspots (we are at or near the solar maximum) that are constant across the video. When viewing the individual images there are some with small dots (satellites?) and blurs (blowing autumn leaves).

Comet C/2023 A3 (Tsuchinshan–ATLAS)
The comet is still visible to the telescopes with an estimated magnitude of +6.8. The tail is fainter and shorter than yesterday. The Vespera II telescope was fitted with a CLS (city light suppression) filter causing the tint to the image. The length of the comet tail can be estimated based on the field of view for the telescope’s digital sensors. Stellina (1.0° x 0.7°), Vespera Classic (1.6° x 0.9°), Vespera Passengers (2.4° x 1.8°), Vespera II (2.5° x 1.4°), and Vespera Pro (1.6° x 1.6°). The jpg images were processed to increase the brightness (Capture One Pro) and reduce the noise (Topaz AI).

I worked for 27 years as a Chemist in the Pharmaceutical Industry developing processes to manufacture medicines for human and animal health. I now spend my time as a photographer and world traveler. My interests include the natural world, wildlife, landscapes, sky, and seascapes, travel, and astrophotography. I look for unique ways of viewing the world and presenting my images. I have traveled to over 55 countries in six continents, often on Semester at Sea voyages. While at home in New Jersey, I spend time on home renovation and expansion of a wildflower garden/meadow.
