Planetary Nebulae

Planetary Nebulae are usually small and often difficult to find by star hopping.
They are the remains of a star that exploded and have a fairly short life.

The attached file lists 71 NGC and IC PN by magnitude and by size.
All the objects are brighter than mag 13, larger than 12" and south of Declination +50.

The columns are
Name NGC or IC
PNG galactic coordinates and name
RA and Dec. Right Ascension and declination (dd is dec in deg)
L" length in arc sec
Dist. approx distance in light years
Type. 1 stellar, 2 smooth disk, 3 irregular disk, 4 ring, 5 irregular form, 6 anomalous form
Mag of PN
Mag of central star
S.B. surface brightness
CON Constellation

Please post your observations of some of these PN.
