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.

Comet C/2023 A3 (Tsuchinshan–ATLAS)

The comet and tail keep getting smaller and fainter. The estimated magnitude of the comet is now +9.1. I am only showing images from the Stellina telescope since the Vespera telescopes are fitted with filters for viewing emission nebulae.
