Full Frame

This is the first full colour image of this Nebula to verify the following faint features and is my
first confirmed result as part of the GPNHS team.

K1-4 in Ophiuchus is a small planetary nebula with a central bright inner oval just 45" across.
The outer features around this planetary nebula were discovered in heavily stretched B&W SuperCOSMOS
Ha data in January 2015 by the Galactic Planetary Nebula Halo Survey (GPNHS) team and as part of
this team, my goal for this data collection was to look for and confirm this very faint outer halo
or system of outer extensions beyond the main inner oval. The outer filaments revealed here extend
the size of the nebula to about 2.5 arc min.
