This is an animation of asteroid 2021 NV5:
https://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2021%20NV5&orb=1There are 186 x 10s exposures, open-loop tracked with Horizon-Tool. The little dot in the center is the asteroid.
The mount is a Celestron CGE Pro and OTA is Planewave CDK 12.5.
It was around magnitude 17.3 at the time, moving at about 360"/hour in RA and 11000"/hour in DEC.
Spaceweather.com estimated its diameter at 14m.
I may try to get some photometry data from this, but it is pretty noisy.
