Description

The Trapezium or Orion Trapezium Cluster, also known by its Bayer designation of Theta1 Orionis, is a tight open cluster of stars in the heart of the Orion Nebula. It was discovered by Galileo Galilei. The Trapezium is most readily identifiable by the asterism of four relatively bright stars for which it is named. The four are often identified as A, B, C, and D in order of increasing right ascension. The brightest of the four stars is C, or Theta1 Orionis C, with an apparent magnitude of 5.13. Both A and B have been identified as eclipsing binaries.

Testing out my new mono planetary cam.

Thought I would see how it did on this object

while I waited for the moon to rise higher in the sky.

I think I can see the two binaries belonging to two of the four stars
