Orion and Eridanus

I admired astrophotos by Axel Mellinger in 2006, and Eridanus Bubble is my favorite.

The area is visible in the widefield Hydrogen-alpha photo in Galaxy Map:

Location: 11,000 feet above sea level near MLO, Mauna Loa Observatory on the shoulder of Mauna Loa in the Big Island, Hawaii
