Campbell's Hydrogen Star

I was shown a new object last night, PK64+5.1, through the 60" scope at Mt. Wilson. It was quite amazing. 8O The star itself, though 1000 times brighter than our sun, did not appear to be unusual. The hydrogen shell it has expelled however, was the most vividly red object I have ever seen through a scope. The thin, bright red ring was slightly elliptical and revealed a slight gap between itself and the star. Some observers could only see the gap on the side where it was wider. We were at 443x and no filters were in use.
Has anyone else had any experience with this planetary nebula?
I will try to observe it next time I'm out with the Starmaster, but would not expect similar results.

I tried to find it, but couldn't identify it among the myriad of stars in the region. I'm afraid that the red colour is more difficult to make out in my 12.5-inch than in the 60-inch at Mt.Wilson.
