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).

Comet C/2023 A3 (Tsuchinshan–ATLAS)

I missed the comet for the past several nights due to early evening clouds and even some much-needed rain. The comet is getting fainter and the tail shorter. The magnitude is now 9.9. The first image is a composite of 31 images (5 min 10 sec) and the second one is a composite of 59 images (9 min 50 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).

Six-Years Ago Today. Northern Red Cardinal. (04-Dec-2018, New Jersey).

Sunspot Activity

The solar disk was observed with a Vespera Pro telescope (250 mm, f/5, 1400 microseconds) using a Solar filter. The sun is near the solar maximum period of the 11-year solar sunspot cycle. The image is cropped to 1204 x 1204 pixels with the apparent diameter of the sun a little less than 0.54°. Processing the image using Topaz AI (noise reduction or sharpening) or AutoStakkert4 (image stacking) did not improve the image.
