Description

NGC 6826 is an interesting and colorful deep sky object but difficult to render because of the high contrast between its core and the tenuous envelop surrounding it. For that challenge I use the fusion of lucky imaging for the core of the planetary nebula and long exposures with Halpha and OIII 12nm. Feel free to look at the upper right corner to see the magnified core of the lucky imaging picture.
