Can you spot the asteroid in the star photo below?

Here is a photo of a telescope at Brazos Bend State park imaging the asteroid "Pratchett". Can you identify what constellation is visible through the dome slit? Note the stars here are streaked because we
used a stationary camera, fixed to the Earth... which is rotating! The images of Vesta at the top of the page were taken with
a camera fixed to the telescope, which turns to track the stars... keeping a fixed orientation in space as the Earth turns
The red streaks were made by people moving around during the
exposure using very dim red flashlights to see their way in the dark. The red "bullseye" on the dome ceiling is
from the Telrad finder scope used to point the telescope. It projects a red bullseye onto the sky when you look through it,
and that's part of how the astronomers using the telescope get it pointed at just the right spot in the sky. But it also projects
a very dim red bullseye onto the inside of the telescope dome!
Was Vesta too easy? See if you can find the asteroid "Pratchett" in the images that were taken by the telescope above.
