Details:
Can you find the comet C/2023 A3 T-A? In this extreme HDR of this morning dusk, I revealed it from data taken near Kovarov, Czech Republic (yes, 49,8 N). Even if almost invisible, the tail is enhanced from 15 exposures (15x1s, ISO 200). Comet was completely invisible to the naked eyes, or binoculars, during taking this shot it was 2-3 degrees over the horizon after the end of astronomical twilight. Used Canon Ra, Tamron 70-200mm@200mm. The foreground is taken as HDR (1, 4, and 8 seconds, ISO 100). Truly challenging, but officially can confirm it IS possible to capture it from the northern hemisphere, even if with advanced processing to reveal it. I believe the next days should be better and better.
