When or for what time did you try to display 2002 NY40? Because at
the moment it has +50 mag (no joke) because we see it from the
unilluminated backside. This is what Guide gives me when I set lim
mag for asteroids to +60 mag:

0.23% illuminated
Phase angle: 174.52 degrees
Elongation from Sun 5.21 degrees (morning sky)

You have to switch Galaxies on in DISPLAY / DATA SHOWN. Then
there appears PGC 63287.

Look at this page. It deals with the accuracy of Guide:

I hope this will help you.
