17-07-2020 01:00h A BW picture. The gas and dust tail are both clearly visible Canon 700D Samyang objective, f=85 mm, f/2.8, T=20x15 sec, ISO 800

16-07-2020 00:35h PiP is of the same date only 10 minutes later Canon 700D, Samyang objective f=85 mm, f/2,8 T= 50 x 7 sec ISO 800. During the exposures I tracked the comet and stars, whence the "blurred" clouds. The foreground trees are taken from one exposure.

17-07-2020 01:45h. First pictures on which the gas tail is clearly seen. The gas tail consists of ions of atoms and molecules, the dust tail of dust particles. Samyang objective: f = 85 mm, f/1.4, T = 20 x 30 sec. ISO 800 Info: en.wikipedia.org/wiki/Comet

13-07-2020 01:00h To the left: 8 exposures f=135 mm, f/5,6, T = 8 x 30 sec, ISO 800 To the right: 25 exposures f=750 mm, D=15 cm, T= 25 x 4 sec, ISO 1600 (prime focus Newton telescope) Field of view is shown in the left picture

13-07-2020 01:00h Combined 4 exposures with total T=32 sec (lower part of the picture is just one exposure)

showing the movement of the comet. At the present distance Earth-comet the white bar (i.e one degree) is about 2,3 Milj km. This gives you an idea of the size of the tail and the distance the comet travels in this 46 hours.

11-07-2020 3:00h the tail is about 5 degrees in length (i.e. the moon on the sky is about 0,5 degrees) Canon 700D with Samyang objective, f=85 mm f/2,8 T=31 x 4 sec ISO 400

11-07-2020 2:45 h Got up early and there he was, clearly visible by naked eye. This picture is a combination of 11 exposures. Also visible some high clouds lit by the sun, noctilucent clouds. Objective Samyang f=85 mm, f/2.8, T=11 x 2 sec ISO 800

There is a planetarium program for the comet Neowise. The comming days it is in the same area as shown here, however the comet bcomes fainter. Best time is between 3 and 4 in the morning theskylive.com/planetarium?objects=sun-moon-c2020f3-mercury-venus-mars-jupiter-saturn-uranus-neptune-pluto&localdata=53.07738%7C7.40444%7CPapenbourg+(DE)%7CEurope%2FBerlin%7C0&obj=c2020f3&h=02&m=05&date=2020-07-11#ra|6.246386079849314|dec|39.69035834673569|fov|50
