When I was processing my M74 data from Sunday night I noticed a distinct moving object that tracked perfectly with my exposure sets as it cycled through filters Ha R G L B R G L B.  Stellarium showed a satellite near the area but moving much much faster than what I captured.

 

 

The captures start at Sept. 16, 11:41pm EST through Sept. 17 4:09am EST.

 

What did I capture??

The CIA would like to have a word with you...

It was likely Asteroid (120) Lachesis @ Magnitude: 13.0; it was the closest and brightest of many in the area.

I believe you are correct!

Welcome to asteroid hunt team !

I observe them quite often, it's one of those targets not affected by light pollution.

Wait, how fast do asteroids like this move? 1 arcminute/m? 2.5/m?

I'm trying to remember from my asteroid hunting days. I believe main belt asteroids cover about 1/2° per day. We would shoot images 15 minutes apart to detect movement when blinking.
