Silhouettes of Objects Passing in Front of the Sun.
Today, I captured images of a jet with a condensation trail and a bird transiting the sun while looking at the sunspots (we are at or near the solar maximum). I was viewing the sun with a Vespera Classic telescope fitted with a solar filter. The exposure time for solar observations with the Vespera Classic telescope is 250 microseconds (1/4000 sec). The Vespera Classic takes ~51 solar images per minute. Over an hour that amounts to 0.765 seconds (or 0.02% of the time).
Comet C/2023 A3 (Tsuchinshan–ATLAS)
The comet is getting fainter and the tail much shorter. You may need to look closely, the comet is in the center of the frame. The magnitude is now 10.5. The first image is a composite of 32 images (5 min 20 sec) and the second one is a composite of 128 images (21 min 20 sec). In the second image there is some movement of the comet head.
