NGC 7008 - The Fetus-Nebula.
Collaboration between Astrodon, Paul Mortfield and Stargazer-Observatory
Located in the constellation Cygnus, some 1200 lightyears away, this planetary nebula, aka PK93+5.2, H I-192, h 2099, GC 4627 is a most spectacular object for a powerful telescope (say larger than 16" aperture). It appears rather bright in a 20" dobsonian, as its visual magnitude is 10m7. In blue, however, it is only 13m3 bright. It holds 1.4 arc minutes in diamter which is considerably large for a PN.
Discovered by William Herschel in 1787 the distinctive shape of the nebula donates the name, reminding the observer of an embryo. The dark hole which can be seen very well in the image near the center, origins back a long time ago, when a seperate nova blew this part of the nebula up.
