Comet C/2020 F3 (NEOWISE)—VIII

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 Æ’/4, 85mm, and ISO 400. The shooting location was Sunset Crater National Monument, an International Dark Sky Park.

Pictures from the Parks

National Parks, that is. Here are several photographs taken this winter in the National Parks and Monuments that are in northern Arizona.

These two images were taken shortly after sunrise at Wukoki Pueblo in Wupatki National Monument. A recent snowstorm had brought snow to lower elevations and I was hoping there would be some snow at this location. No snow but the sunrise was still pretty nice.

Later that morning in Sunset Crater National Monument, where there was new snow, a small amount of snow on the namesake crater helping to reveal its subtle textures.

The next two images are from Grand Canyon National Park at sunrise. A recent minor storm had left some low clouds and fog in the lowest reaches of the canyon. As the sun rose higher and the canyon walls warmed the fog was lifted up and out of the canyon producing some eye-level clouds for a brief moment.

Finally, we have a panorama of the rising nearly-full Moon in late afternoon. Wonderful!
