The Owl and its Outer Ring

A deep-space image of the Owl Nebula (Messier 97), a round, blue-hued planetary nebula centered against a star-filled black background. The nebula shows a darker inner core with two eye-like cavities and a faint, extended outer halo surrounding it.

Image Description and Details: The Owl Nebula M 97 is a famous and very often photographed object. But what you don't often see, is the faint outer ring. Here I took quite much effort in processing and was able to show the bright inner core as well as the outer ring at the same time. You see 20 hours of integration time using dual narrowband filters. Hope you like it!
