Description With no filter the nebula was a large pale disc filling about
1/4 of the field of a 15 mm Plossl. The 'eyes' were not very obvious. Using
a 9mm eyepiece with an OIII filter the nebula was clearly non uniform, dark
features were clearly visible but at first glance the nebula had a more
foamy than owl like look. With study the circular nature of the two central
dark patches and a third near the edge, became apparent. The Owl is a 
fascinating and rewarding object.

Regrettably since these were found using digital setting circles there is no
finder information for these objects.
