I returned to the far corner of my backyard with a view to the west where Comet C/2023 A3 (Tsuchinshan–ATLAS) was still high enough above the trees be visible just after dusk. The estimated magnitude of the comet was +4.7. I couldn’t see it directly, but easily captured an image with Vespera Pro telescope. This is a composite of 30 stacked 10 second images (300 second exposure).
