While processing my DSO photos (53 of them total) of NGC 2175 from February 3rd, 2021 (19:02-21:41 EST):, I found a slowly-moving object.  It had a easterly motion of 14.16 seconds/hour across my field of view.  Coordinates were RA 6h09m06s/Dec 20:30:00 putting it way outside the ecliptic, so not a planet or asteroid.  Maybe a comet?  Weather balloon? If it had a circular solar orbit then its orbital period is about 10 years.  I cannot find a website that might allow me to enter the dates and coordinates to determine what it might have been.  I'm intrigued and wish I had processed these photos earlier.  The first image is a composite of 5 equally-spaced photos spread over 160 minutes, superimposed on NGC 2175 (blended at 25%) while the 2nd image is the same without the brightness fiddling.

 

My lat/long is 43.826/-78.601. Prevailing winds in my area are generally west to east, so a weather balloon can't be ruled out - although it would have been an incredibly slow-moving balloon, having travelled only 5-10 meters in 2 1/2 hours!  Does anyone have any ideas?

I wonder if it could be an object inside a geosynchronous orbit and not in an orbit running around the equator.  You made an interesting catch! :)

It appears it's the 150 Nuwa, a main belt asteroid. It's off from the solved position shown in orange because I didn't specify the time of the observations, but it's unlikely something else. waytogo.gif
