OBSERVING ASTEROIDS (2)

The asteroid observations on this page were made in July 1998 with an Audine camera prototype mounted on an 8 inch LX200 telescope. The camera and the telescope were controlled via a local Ether network from a control post 40 metres away from the telescope to be exact, thanks to the AUDACE software. The computer situated near the telescope pier (a low class Pentium) handles pointing and operating the camera, while the computer at the control post performs image processing in real time.

An asteroid (J97E30Q) slided down this image... Can you tell where?
( Composite of 5 images of one minute each )
In this animation of 3 spaced images of 5 minutes each, the asteroid makes itself visible thanks to its movement. This asteroid was found by C. Buil in the beginning of March 1997. It is labelled as "numerable" in the Bowell database. Observation by Alain Klotz and Denis Marchais.

Asteroid J80UL. Animation of six images, the first three of them are spaced 5 minutes, the last three too but he two series are spaced more than an hour.   The lower brightness of the three last images is due to the fact that the asteroid was much closer to the horizon than on the first three images. labelled as "numerable" in the Bowell database.
