Planetary nebula NGC 1535 is a victim of circumstance. Take a look at its facts. Its bluish disk spans about a minute of arc, which is quite large as planetaries go, and shines brightly enough to be visible through giant binoculars. Its central star glows at magnitude 11.6, creating a surreal scene resembling a disembodied human eye, which led to the nickname "Cleopatra's Eye." Those in the know rate NGC 1535 as one of the sky's finest planetary nebulae. Yet this enticing target remains unknown to many backyard stargazers.

Phil:

 

Thank you for another cosmic challenge. NGC 1535 is a favorite of mine, particularly in a large scope. As you say, its one of the most beautiful planetaries..

 

I locate it by starting at Zaurak, gamma Eradini (mag 3) and moving 4 degrees (one Telrad diameter) towards Rigel. NGC1535 is almost on a direct line from Zaurak and Rigel.

 

I do not believe I've seen NGC1538 so If it ever clears up, I have to give it a try.

 

Happy New Years

 

Jon

Great target Phil.  Definitely missed its presence in the past, so I appreciate your exposing its presence.  jd
