Yesterday the sky was overcast, so no comet images. The comet and tail keep getting smaller and fainter. The estimated magnitude of the comet was +8.2. I am only showing images from the Stellina telescope since the Vespera telescopes are fitted with filters for viewing emission nebulae.

Full “Beaver” Moon
The full “supermoon” this month was extra bright because it was closer to earth. Once it was above the trees to my east, I used the Stellina telescope to record images for a time-lapse video. While reviewing the images I found several images with silhouettes of birds passing in front of the moon. At this time of the year, birds are migrating south, often at night. Even though it may have been a large bird, it must have been a long way away. The cropped image is about 4x magnification.

While reviewing the solar images with several sunspots, I noticed what appears to be a pair of satellites transiting the solar disk over a 4 second period. I have a composite image and the individual images of the transit. I also found images with silhouettes of birds (Turkey Vultures?) and one with an unidentified object (military jet?). I’ve also added the time-lapse video if you want to look for other objects passing in front of the sun.

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).

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).

Jets and birds passing in front of the sun with sunspots.
The sky started out clear and sunny with clouds coming in later in the day. The Stellina telescope was fitted with a solar filter and set to observe the sun and sunspots. While reviewing a time-lapse video of the 18500 images (7h 45m compressed down to 10m 15s) I noticed the silhouette of a couple of jets and a bird (Turkey Vulture). Let me know if you see anything else (other than clouds) passing in front of the sun. It was windy with leaves falling from the trees. Even though it is Halloween, I didn’t catch a silhouette of a witch on a broom flying past the sun. By evening, the sky clouded over, so no images of the comet or other night sky objects.
