Asteroid 2011 OB30 mag 20.9

Observation of minor planet 2011 OB30, night 23/24 OCT 2020.

Objective: Astrometry to refine its position.

Taken 11 images of 600s Clear @-25º. SCT C14, KAF3200ME.

Target was off of the predicted position by : deltaRA =-7.7' deltaDec -3.9'

Here is a stacked image from 10 images using the asteroid velocity and direction to sum and reveal its position while the strars get trailed.

This is a very faint target for my equipment, almost mag 21. Below is an animation of 9 images where you can see the how faint it is..
