Description

The Cat's Eye Nebula is a planetary nebula in the Constellation Draco. The outer shell is built mostly from ionized OIII gas with minor attributes of hydrogen gas. The inner core is very bright but shows some interesting structures.

The image is a combination of narrowband images for the shell and RGB images for the core and the stars.

TS 130/910 mm apo refractor and ZWO ASI1600mmp.
