Summary

[edit]
Description

edit 12/8: I uploaded a new version without the sii channel to make the nebula look a bit more natural. it is no longer green.

this is a pretty planetary nebula, observed by ESO's New Technology Telescope. the nebula appears very green because ha is mapped to green while the sii is mapped to red, this nebula not having very strong sii emissions. I debated whether or not to include that data, but I think it's good to have. there's also some newer VLT data available for this object, but the exposures were much shorter and the chip gap ran through the nebula.

red: ntt/efosc ha#692 green: pseudo

blue: ntt/efosc oiii#687
