A week or so ago I took some more shots of M1, the Crab Nebula in Taurus.
When I was processing the image, I noted an asteroid (OK, minor planet) in the images. The attached image is an animation of 9 5-minute exposures taken on 15-Jan-07.
The asteroid is the moving object at 12 o'clock, moving from top to bottom.
As best as I can tell, the asteroid is 822 Lalage, a fairly bright minor planet at magnitude 14. The exposures include those made without a filter and with the red filter. The green and blue shots are dim and uninteresting.
A larger image is available at my site. The attachment just fits within the size limits for the forum .
The images I took the next day have yet another minor planet in them. Great fun imaging near the ecliptic!
