Description

Bad weather here, so I decided to rework on my data of Abell 21. :-) Even if I only gathered bicolor data (H-Alpha and OIII), I wanted to get that typical impression of a Hubble pallet. I think it's been worth it. :-)

Also known as Abell 21 and SH2-274, the Medusa Nebula is an old planetary nebula some 1500 light-years away in the constellation Gemini.
