Description

20 hours of Narrowband imaging of Owl Nebula (Messier 97) from the pristine skies of SPICA so as to capture the rarely seen outer gas shell of the planetary nebula. Narrowband data is rendered using a variation of the HSO palette.
Years ago, I saw the gas ring around the nebula but with no detail. Searched through multiple photos but most of them did not clearly reproduce the ring so I tried to image it.
