NGC 3699 Planetary Nebula in Centaurus

This bright 11 magnitude planetary subtends a visual diameter of about 45.0 arcsec.
However it shows very complex and extended outflows and filaments extending over several arc-minutes in this long NB exposure.
The diffuse H-Alpha emission could be interacting with the planetary nebula.
