Hi Dennis,
Fantastic job! Were you able to determine how close 2022 NR's actual position was to the predicted position? BMD's been reporting large differences between the predictions from elements available before a close approach & the actual position during the close approach as the gravitational perturbations take effect on the NEO & alter the trajectory.
It looks like your tracking & seeing were very good - very little wiggle in the star trails. Which exposures were done first, top left or bottom right? That was still quite a lot of motion in just 5 minutes.
I'm glad that you're getting some decent weather.
How faint an NEO do you think that you can capture? I know that you imaged some faint moons a while back. 2022 KY4 will reach peak brightness of 17.3 magnitude on Jul 19 at 0000 EDT when it will be in Telescopium at 0.04 AU moving at 14.3"/min. If that's detectable, I'll provide more info later.
