Pease 1 - Planetary Nebula in M15

Pease I (Pegasus)
Pease I - a planetary nebula in the globular cluster M15 - is the 
small 'red' object whose position is indicated by the white cross-hairs
This false colour image uses Ha filter frame for red, 
and V filter frame for blue and green.
The Pl. Neb. is highlighted due to its high excess of light at Ha wavelengths, 
and appears 'red' compared to normal stars which appear whitish in this image.
