Description

I also took about 2 hours of Ha and Oiii of this PN, but they are not needed. This is a very bright PN and RGB alone is very strong. The central star of this PN is exceptionally unusual. See below.

NGC4361 is a very small PN measuring 1.8 arc minutes across, and transits for me at 35 degrees.

NGC 4361 is a planetary nebula in the constellation of Corvus. It is included in the Astronomical League's Herschel 400 Observing Program.

NGC 4361's central star is an extremely hot [WC] star. Its temperature is at 270,000 K, hotter than every Wolf–Rayet star known. It is nearly 18,000 times brighter than the sun, but is only 6.1% its size. This star is only 1,230 years old.
