All-sky cameras are employed for meteor surveys, and they only catch relatively bright objects. For satellites, I don't think you go beyond mag +2 with such a camera. So for *small* objects in Leo it is useless, imho. Another point is that the astrometry (positions) from such a wide field view is not very accurate. Recently I did an analysis of all-sky images from a recent Soyuz r/b re-entry imaged by several of our meteor all sky camera's, and residuals stay very large.

A better strategy would be to set up a fence consisting of several Camera's (photo or video) with smaller FOV.

One reader emailed to say that DSLR mechanical shutter life might be an issue with all-night short time exposures taken nightly.
