Hi, I'd like to find out if anyone has any notes on observing this planetary nebula in Canis Major. I'd like to try to see it visually, I have a 14.5 Dob and have access to a 24 inch dob.

I didn't even know it existed! In Kent Wallace's VOPN tome, he writes that it was visible with a 20-inch and Jack Marling saw it with a 17.5-inch. I'm sure my 16-inch could pull it in and since you live farther south than me, I suspect you could see it. But it may be tough even with a filter.

Thanks for your response Scott, I will definitely give it a shot next new moon!
I observed it quite awhile ago (like 38 years!), so can't say I recall the observation ;-) But here's what I wrote with my 17.5" f/4.5 using 130x and an OIII filter.
Faint but easily visible with averted vision, round, estimate 20"-30" diameter, V = 15.0-15.2. Located 6' S of mag 7 HD 51202.
