Observation Notes:
This planetary nebula was a nice detour after traveling along Kemble's Cascade and the sparkling splash of NGC 1502. It was readily evident as a soft disc at 48X. At 120X, it had a very slight aqua tint. I found it too faint to examine well at 240X, so I kept it to 120X. Averted vision revealed a thick, subtle annular shape. The southwest edge was brighter and the northeast edge seemed to have two brighter knots. The northwest side appeared somewhat flattened. I saw no evidence of a central star.
Object Information:
NGC 1501 was discovered by Friedrich Wilhelm Herschel in 1787. The planetary lies roughly 5000 light years away and is about 1.4 light years in diameter. It possesses a 14.5 magnitude Wolfe-Rayet star at its heart. It is also cataloged as: PK144+6.1, H IV-53, GC 801, PN G144.5+06.5

Hey Jeremy, hope all is well. Your work is so good that ine almost thinks that its a B&W image...another fabulous sketch. In fact, I had it in the eye piece just about an hour ago...there is no difference between the sketch and what I saw...

Hi Tony, thanks! It's been a while since I've pulled this beauty up in the telescope.
