Binocular comet Churyumov-Gerasimenko, Orimattila, Artjärvi, Viestikallio

I tried to make the comet 67P / Churyumov-Gerasimenko dust dust / dust trail more clearly visible with a longer exposure time of 30 minutes than with a 5-minute exposure taken two days earlier https://www.taivaanvahti.fi/observations/show/102096 .

The dust trail was now dimmer. The transparency of the atmosphere may not have been as good as the 8.11.2021 observation or the dust trail is but dimmer because there are two more days on the perihelist. However, the dust / dust trail stands out in front of the comet's core, continuing beyond the image. The first negative image has normal exposure stacking of 20x90 seconds (2021-11-10 23: 33UT), and the second image has reduced stars in the image processing process.
