My first thought was, oh crap, I almost forgot about that! I further completely forgot that Venus and Mercury would be very close tonight.
On Thursday night, a few hours after I photographed the Orion Nebula, I searched for the asteroid and dwarf planet known as Ceres.
The best way I can confirm/reconfirm which dot was Pluto would be to sketch the area around HIP 94372 once Pluto has moved significantly.
I wanted to confirm my finding as best as I could, so I started hunting for noticeable star patterns in the area of HIP 94372.
I have now learned how high Mercury can truly be.
