The Flying Bat and Squid Nebula (Ou4) - A Deep Look

• Connection to Category: Discovered only in 2011, Ou4 is one of the sky's most elusive targets. It is an extraordinarily faint bipolar outflow of ionized oxygen surrounded by a sea of hydrogen. Capturing its structure demands both hours of exposure and hours behind the computer screen processing, embodying everything the Deep Sky Observation category celebrates.
