This image captures faint molecular clouds spread across the northeastern corner of Eridanus.
The bright star at the left edge of the frame is ω Eridani. LBN 906 locates 3 degrees west of it, and the densest molecular cloud LBN 917 is lying 1.5 degrees west of the star.
These molecular clouds are part of the large star-forming region known as the Orion-Eridanus superbubble, and the way the gas disperses southwestward like a windsock is striking.
Additionally, you can detect that the extremely faint but pervasive Hα-emitting nebulosity extends across the entire field of view.
