Moonflowers

I had another camera in the sunflower field.  This one faced south and caught the arcs of stars and planets near the ecliptic.  Eventually the full moon entered the scene.

Northern Sunflower Trails

I have long been fascinated by sunflowers.  On my travels across the prairies of the Dakotas I loved to encounter sunflower fields with their collective bright yellow heads all aimed in the same direction.

Comet Neowise

A photogenic comet visits in a year when the world is shut down by a virus.  We can still appreciate its beauty and find an isolated area in a nearby park.  Photographing comets has become considerably easier in the twenty years since my previous attempts trying to capture Comet Hale-Bopp on film!

Ayres Natural Bridge Park

The Earth moves under the North Star while the moon illuminates the red rock canyon wall of Ayers Natural Bridges Park.

We were pleasantly surprised to discover this hidden gem in Wyoming, land donated from their ranch by the Ayres family.  The park was entirely free, including campsites, but no pets are allowed.  This is considered a benefit to some.

Amateur astronomers from around the country gathered at the observing facilities of the Minnesota Astronomical Society on a warm July evening.  They discuss their observing plans for the night and  wait in eager anticipation as the brighter planets start to appear in the fading twilight.

Minneapolis Moonrise

The moon rises over the cityscape of Minneapolis as its buildings start to turn on their own lighting..  This is the “supermoon”, a designation for when the moon is unusually close to Earth and hence, appears even larger than expected.
