Totally guessing but that black streak at the top could be it = frame rate to slow ?
No, that's a nice capture of a filament!
Belt, did you take any video before or after the transit? I'm guessing that maybe you forgot to hit record at the critical moment.
Thanks, James and scngc7317. Definitely hit record 1 1/4 minutes before. Sat there watching the green bar scroll across while waiting for the transit to happen. But, I'm pretty sure I have it figured out now ... and you are both right.
I was rushing ... never a good thing where this stuff is concerned ... and I didn't notice I had my gain set way too low. As a consequence, the exposure (shutter speed) was too high and since the ISS is moving so fast I totally missed it. Comparable in terrestial photograph to trying to capture a fast moving object ... race car, arrow in flight, hummingbird's wings, etc ... with the shutter speed set too low. Just aren't going to stop the motion.
But I didn't think that ... ie low gain and high exposure ... would introduce artifacts into the video. That is, I was pretty sure it was a filament ... but you had me questioning myself there for a while scngc7317. :-)
