This effect applied to a star stack lets the sky appear populated by a trilion of comets. I decided to apply this effect to the scene to get a different night image of the Blue Lake, in Cervinia.
Another look at the comet Neowise when it came to visit. Taken with our trusty nikon d3100 and our Nikkor lens.

Comet C/2020 F3 (NEOWISE) at 85mm focal length (1.5mag), Petershausen, Bavaria, Germany
Komet C2020F3 (NEOWISE)_02
Comet Neowise streaks across the sky in the Badlands of South Dakota!
Not the best image with some cloudiness and haze in the sky, but was pretty successful using just long exposure. Most people who got terrific shots used multiple shots and stacking.
Thanks for comments and Explore while I was away!

Comet Neowise is soon to set on the day it makes its closest pass to Earth. Even though it's at it's closest, it's amazing how much it has dimmed over the span of the last week as it got further and further away from the Sun. Seen from an undisclosed location in Northern Illinois.
I had recently reworked this stack with a new workflow and wanted to upload it again.
This stack is a stack of nearly identical images (only a couple degrees of rotation of the heavens difference between each consecutive shot taken one after the other). It is not a composite of different images.
Knowing that, if you are paying attention, you may find yourself scratching your head as to how I got this shot.
Pretty sure its not an airplane, but I really don't know what this is. The tail looks like a comet, but the red has me confused. All the captures of Comet C/2021 Leonard have green in them not red. I did have an astro filter on the camera. Pointed in the SW sky @ 6:37 PM Pacific time.

Comete C 2022-E3(ZTF) / 80ED / ASI1600MC / 30x120s.
Composite de deux images avec SIRIL et Photoshop (une avec la comète seule et l'autre avec uniquement les étoiles).
My first attempt trying a little more serious astrophotography. Yikes! I took a series of 7 images, each for about 30 sec. Stacked and then processed. The comet is pretty small, and the sky is big, but I think it turned out ok. The learning continues!
Comet C/2024 G3 (ATLAS) continues to decorate the evenings of the southern hemisphere. At dusk it shines on the horizon along with the last lights of the setting Sun. In this photograph, taken with a Nikon D5600 camera and a Nikkor 135 mm lens, it looks bright and imposing over a curtain of Eucalyptus. Enjoying the scene with the family has become part of the last hours of the afternoon.

Public art for Christmas – It was made for Christmas 2007. This spiky blue "Comet Glass Star" displayed at Campo Santo Stefano was made by the artist Simone Cenedese in Murano. Across the canal is San Pietro Martire, a church with history dating to the 1300s.
When I'm not checking the Christmas artwork, you can find me on Twitter
A composite image - just had to move the comet over a tad for aesthetic purposes (being I went down to Manukau Harbour to specifically try and get this shot). Auckland New Zealand
I forgot I had taken this shot of an old Comet down the road from where I use to live. Wonder where it ended up?

It was very hard to find him and in the end I did it with just 70mm on my camera and lens. Quite a challenge for sure. I now not perfect but for 70mm not to bad :-)

C/2022 E3 (ZTF) is a long-period comet from the Oort cloud that was discovered by the Zwicky Transient Facility (ZTF) on 2 March 2022.[1] The comet has a bright green glow around its nucleus, due to the effect of sunlight on diatomic carbon and cyanogen.[6][5]
The comet's systematic designation starts with C to indicate that it is not a periodic comet, and "2022 E3" means that it was the third comet to be discovered in the first half of March 2022.[5]
The comet nucleus was estimated to be about a kilometre in size, rotating every 8.7 hours.[7][8] Its tails of dust and gas extended for millions of kilometres and, during January 2022, a third anti-tail was visible.[9]
The comet reached its perihelion on 12 January 2023, at a distance of 1.11 AU (166 million km; 103 million mi), and the closest approach to Earth was on 1 February 2023, at a distance of 0.28 AU (42 million km; 26 million mi). The comet reached magnitude 5 and is visible with the naked eye under moonless dark skies.[10][11][12][13] (Wikipedia)
