This 1874 lithograph was created by Étienne Léopold Trouvelot with the 15-inch refractor at the Harvard College Observatory, for the purpose of measuring the nebula’s extent. A glass plate with dark black lines was placed on the focus of the telescope for marking placement. No wonder it shows no central star.

The constellation Orion the Hunter hosts two of the 10 brightest stars in the sky, Betelgeuse and Rigel. At magnitude 0.5 and 0.2, respectively, Betelgeuse (orange star at upper left) and Rigel (blue-white star at lower right) stand in stark contrast to many of the surrounding stars.

Why do astronomers measure stars in magnitudes?
