For a few days Comet C/2020 F3 (NEOWISE) shared the sky with two other comets. Visible in this image are:
Nikon D750, 85mm, ƒ/2.8, ISO 400, 30 x 120 seconds. Shot at Wupatki National Monument, an International Dark Sky Park, in northern Arizona. A direct link to the full-size image is available.
Comet C/2020 F3 (NEOWISE) is growing dimmer in the evening sky although is still visible in binoculars. Longer exposures are now necessary to reveal the fan-shaped tail.
The second image is a wider view that shows that Comet C/2017 T2 (PANSTARRS) and Comet C/2019 U6 (LEMMON) are also visible albeit both are very small and faint. M53, a globular cluster, and M64, a spiral galaxy, are also visible and labeled. A full-size version of this image (~2.1 MB) is also available.
These images are a stack of five images each 120 seconds at ƒ/4, 85mm, and ISO 400. The shooting location was Sunset Crater National Monument, an International Dark Sky Park.
