Seventeen Years-Ago Today. Big Thompson River, Moraine Park, Rocky Mountain National Park, Colorado. (02-Dec-2007)
Author: David Mathre
I am a scientist by training (Eckerd College, BSc; Caltech, Ph.D.). 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.

Nine-Years Ago Today. Red fox on the side of the road with a road-killed deer. (01-Dec-2015, New Jersey)
Comet C/2023 A3 (Tsuchinshan–ATLAS)
The camera in the Stellina telescope stopped working. I’ll be contacting Vaonis support to try and figure out what is wrong. So tonight, I only have the Vespera-Pro telescope capturing images of the comet. The magnitude is now 9.6. The first image is a composite of 31 images (5 min 10 sec) and the second one is a composite of 247 images (41 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).

Comet C/2023 A3 (Tsuchinshan–ATLAS)
The comet and tail keep getting smaller and fainter. The estimated magnitude of the comet is now +9.52. I am only showing images from the Stellina and Vespera-Pro telescope which were not fitted with filters. 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°) 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).

Comet C/2023 A3 (Tsuchinshan–ATLAS)
The past two nights clouds prevented observation of the comet. The comet and tail keep getting smaller and fainter. The estimated magnitude of the comet is now +9.45. I am only showing images from the Stellina and Vespera-Pro telescope which were not fitted with filters. 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°) 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).

Comet C/2023 A3 (Tsuchinshan–ATLAS)
The comet and tail keep getting smaller and fainter. The estimated magnitude of the comet is now +9.2. I am only showing images from a Stellina and Vespera-Pro telescope not fitted with filters. 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°) 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).
