M 97 – The Owl Nebula with MWT and RASA

The Owl Nebula, a planetary nebula situated about 2000 light years away in Ursa Major, is a quite bright PN and therefore often imaged. I picked it as last nights target since the moon is out and it is a great Ha and Oiii object.

This is a mix of data. I collected the detailed Ha and Oiii data with a Planewave 17 CDK (the “Margareta Westlund Telescope”) that I have access to down in Spain, and mixed this with IDAS NBZ data collected with my dual RASA-8 rig in Sweden. The latter contributed especially to the star color and the dusty and often missed outer ring.
