In eastern Puppis, at declination -34*, is a 7th-magnitude variable star known as RS Puppis. It's a 41.3-day cepheid that around 1960 Bengt Westerlund discovered had a small nebula up close to it. This nebula is noticeable on DSS red images and has a wonderful Hubble image.

So, my question is, has anyone here observed the nebula? I can't say I've heard of any observations. Kinda wondering if I have a shot in my 16-inch...

Tried it with 32“ under exceptional conditions, but had no clear success. There was a hint of glow at the brightest section of the inner nebula, but the star itself was so disturbing that I count my observation as negative.

Never used one but.... maybe try an occulting bar?

I’ve never looked for this nebula and Uwe’s report seems to make it pretty hopeless in a much smaller aperture.

I was ready to add some history, though, and mention it was discovered much earlier in 1920 on plates taken at the Sydney Observatory in Australia and described as "One of the most curious stars seen. Nebulous envelope most developed on south-preceding and south sides.” But that description applies to the AG Car nebula, which Thackery rediscovered in 1950.

Has Jimi tried it on the Leviathan of Fort Davis?

Don’t know, and it’s not been on my observing list during any visit.
