Summer! Shorts & shirt sleeve observing!  Mosquitoes! Yes, this is the season for planetaries that stretch from horizon to horizon.  There are so many great objects to view during this season, it was difficult to pare them down to just 25.  For in the span of from 15h R.A. to 21h R.A., my data base contains 396 PNeb's, which is 66% of the entire collection.  So even though I have only included these 25, be sure to down load   whatever additional objects you would like to check out from the on-line data base. As always, any observing reports that you would like to make on these objects are welcome here at blackskies.org.  I will include them in the Reports section.
You can send them to douglas@blackskies.org   and Thank You! (Continued)

All of the objects included in this list are from the NGC / IC catalogs and with the exception of two, are above -40 degrees declination. So, unlike the Spring list, northern hemisphere observers have the edge, in as far as this list is concerned. But with objects as fantastic as M57, M27, the Blinking Planetary, and the Cat's Eye Nebula, and all lying north of the Celestial Equator, it's a great season for planetaries!

 PLANETARIES WITH OBSERVABLE CENTRAL STARS
NGC 6543:    In Draco, this PNeb has a central star which might be just a bit  more visible using   low power since the PN itself has a pretty high surface brightness.
NGC 6826:   The famous Blinking Planetary -  since the central star is relatively bright, when    a person looks at the star, most of the nebulosity can not be seen; when glancing  away from the star, the nebulosity 'pops' into view, hence it appears to blink 'on'  and 'off' as you look towards and away from the central star.  Cool!
NGC 6853:    M27, the Dumbbell, one of the most impressive objects in the night sky.  Look for  the central star using high power. It is one of the hottest stars known, with a temperature in excess of 125,000 degrees K.
