Asteroid 2010 WC9 about 18 hours before its closest approach to Earth (~126,000 miles).

It's the faint streak in the middle of the image. It was only about the size of a football field.

ISO 6400 was necessary to even pick it up this well with our 6" TOA-150 refractor.

Exposure time 6 minutes. During this time, it moved roughly the distance

between New York City and Los Angeles.








2017 Total Eclipse


Here are some of our 2017 eclipse images.

They were taken from a field near Lyons, Oregon

at a point about 2 miles from the centerline.

The prominences (redder areas) show side views of large

storms on the surface of the sun. Some of the ones visible here are

large enough to fit 8-10 planet Earths - maybe larger.












M31 - Andromeda Galaxy





M45 - Pleiades




Venus-Jupiter Conjunction June 30, 2015

Venus was about 48 million miles from Earth.

Jupiter + 4 moons were about 565 million miles from Earth,

or about 12 times farther from Earth than Venus.

Asteroid 2004 XP14 Flyby

On 07/03/06, this asteroid passed by Earth at a distance of only 269,000 miles,

or slightly greater than the distance between the Earth and the moon.

This 25-minute composite image shows the path it took toward the

upper right corner of the frame as it was streaking away from the Earth,

about 18 hours after closest approach.




Asteroid 2007 TU24 Flyby

On 01/28/08, this asteroid passed by Earth at a distance of about 334,000 miles.

This 10-minute image was taken a few hours before closest approach.

Its movement was from left to right.



Comet 2006 A1 - Pojmanski

The stars are streaked because the mount was tracking the comet.

The comet was moving north, toward the top of the image.

So the stationary stars appear to be moving south, toward the bottom.
