I see a lot of small satellites while observing moving very fast through the field of view. One evening as I was setting up and aligning I looked through the EP just as the ISS went through the field of view. I thought the alien invasion had started
. I had a pretty good idea what I had seen and a quick look on Heavens Above proved it. Most satellites I have spotted take two or three minutes to cross the sky so ten minutes must have been a very long way out.
