Hello... I'm not 100% sure this is the right sub-forum, but couldn't find one that was a better fit. I was imaging the Iris Nebula on the evening of 10-NOV-2013 and had an object pass through 4 of my subexposures. I searched www.heavens-above.com
and found nothing. I was hoping to understand what this space junk is. I've had plenty of satellite and plane tracks move through my FOV, but what caught my eye was it's very slow apparent motion. It was caught in 4 of my 60s subs, and transited my 25 arcminute frame in a full 3 minutes. It was also pulsing in brightness so I assume it was rotating at 4 RPM.
Here's what I know
-Moving past NGC7023 which was very high in the sky at the time
-You can get an idea of the brightness (centeral star in 7023 is a Mag 7)
-Seen from Milford, MI, USA
I stretched the histogram to see better here, this was a 60s frame.
Is this a fools errand?
