Working conditions (click on images for full size) :
Left : entire FOV of the (full spectrum) Canon 1100D. The asteroid is the small vertical dash obtained with 20s exposures.
Looking with a 24 mm eyepiece, the field is even much larger and I could just see about 3-4 stars and guess a few others !
I never saw anything moving fast enough to be notices in about 1 min and probably did not see the asteroid ...
Right : Zone chosen for the video below (1920x1080)
