Owl Nebula (M97) in HOOrgb
Always a difficult object to me, so small, so dim... and always come back and I try to take something... if you've ever struggled with it, you know what I mean :D a perfect example of planetary nebula.
The Owl Nebula is a planetary nebula located approximately 2,030 light years away in the constellation Ursa Major. The nebula is approximately 8,000 years old.
In that case is a little bit more that 50 hours of integration, using only a small area of the sensor because the small size of this object, heavily cropped after a drizzle process and still at 0.34 arcsec/pixel.
