Summer's Blue PN: NGC3918

Southern summer has the Carina end of the 'Carina-Sagittarius' galaxy arm high overhead. Rich and dusty, it is packed with remarkable nebulae and star-fields. This 'gem' needs some magnification, but is I think the brightest and bluist of any PNe I've seen. No one else sees a central dimmer region! As summer advances we see more and more of this dense galactic arm until mid-winter,  when we gaze toward the MWG core.
