Comet NeEOWISE and the Big Dipper over Yosemite Valley

Here's a photo showing a slowly fading Comet NEOWISE C/2020 f3 below the Big Dipper. I was in Yosemite on the south rim next to Sentinel Creek with a clear view of the sky. I was hoping to get a view of the comet floating above El Capitan, but the moon was just past new and was setting so there was no light for the landscape. So I turned my attention to getting pictures of the comet with the Big Dipper so it would have recognizable stars around it. It's above two stars in the constellation Leo Minor. It's closest to the earth on this night, but farther from the sun so it's not as brighter as before.

ISO 6400, 30-second exposure, f4, focal length 20mm. This image was cropped to high light the constellation and comet below. 

Remember, it's not just a picture, it's a story!

Comet NEOWISE over Sacramento, California

These photos are of Comet NEOWISE, aka C/2020 F3, taken at about 4:39 AM Sacramento time on July 12, 2020. I, Bob, had driven to the west end of the Yolo Bypass, which is between the cities of West Sacramento and Davis, California. I was looking northeasterly when I took this shot.  Other photographers were out in these predawn hours to get photos of it, like I was. The horizon is the Sierra foothills.

At this point Comet NEOWISE is on the outbound part of its orbit after already whipping past the sun. The tails of comets are created by and directed by solar radiation, which means they always point away from the sun. The sun is below the horizon in this view and the tail is pointing away from it.

While I was getting shots of the comet, a freight train passed by me on the nearby tracks.

Remember, it's not just a picture, it's a story.

Half Dome by half moonlight on a snowy February night

We visited Yosemite Valley to try to capture the "firefall" effect of Horsetail Falls at sunset in mid-February 2019 (pictures of that will be forthcoming).  Afterwards, Bob cross-country skied a lap around Ahwahnee Meadow and noticed that the half moon was lighting up Half Dome in a way that brought it out, while not washing out the stars above it.  He got his tripod and camera and shot these long exposure shots from a corner of the meadow.

While Bob was taking the first photo, the Valley Shuttle bus approached while the shutter was open.  The second photo was without a vehicle approaching.

Remember, it's not just a picture, it's a story.
