(meteorobs) Orionids in a row

[meteoreye at comcast.net]

Marco raised a very good question. Were  these visually observed, or only seen on the photographs after the fact?

That's one reason why even though we have a video team bringing up an all sky camera at the NJAA, 
I will persist in my visual observations, since a dozen years of experience provide a way to cross validate what the video system detects.
