Binocular comet ztf - 28.1.2023 at 00.45 - 28.1.2023 at 01.20 Helsinki Observation number 111736

Visibility III / V

Pertti Ankkuri, Ursa (Helsinki)

Well, that comet was found in the sky of Helsinki when you looked really hard. Light pollution and hazy air added enough challenges. The picture was taken with a basic system camera and (18-400mm) 400mm lens, aperture f/6.3, ISO 4000, 15s exposure. The image has been edited with Rawtherapee 5.9 to make the comet stand out better.

The video clip has 74 images that have been assembled in Openshot v.3.0. The subtle movement of the subject compared to the stars in the background stands out.
