3towers Observatory Asteroids
The early 3towers Observatory asteroid images were taken on a 12-inch LX 200 telescope using a focal reducer at f/6.5 with an Apogee KX260 CCD camera or an Apogee AP7 CCD camera running under MaxIm DL/CCD.
More recent images (since March 2012) were obtained with a C-11 HyperStar combination with either a Starlight Xpress SXVR-H9C single shot color camera or a Canon 60Da camera.
All images are oriented with the North at the top and the West to the right.

This shows Juno's motion through the
sky. It consists of ten individual 60-second exposures
taken in succession and put together into an animated
feedback loop. |
| Asteroid 345 Tercidina |

Animated image
Tercidina's motion through
the sky on the evening of 1 December 2005. The image is
a combination of approximately 20 ninety-second
exposures taken through a V filter every five minutes
combined into an animated feedback loop. Near the end of
the loop, Tercidina was only 7 degrees above the Western
horizon. |
| Asteroid 1999 KW4 |
Asteroid 1999 KW4
made a close approach to the Earth on the week end of
May 26-27, 2001. It became approximately 10th magnitude.
On the evening of Saturday 26 May from 10:25 to 11:00pm
MST (05:25-6:00 UT 27 May), seventy-five successive
15-second exposures of the asteroid were taken at the
3towers Observatory with a Meade 12-inch LX200 telescope
and an Apogee AP7 CCD camera.
Fifteen of the images were
added together to produce the track of the asteroid
across the CCD field. The images were taken through haze
and clouds.

An animated GIF image of the asteroid tracking across
the sky was also made. The asteroid travels from the
lower left hand corner of the frame to the upper right
hand corner of the frame.
