Wow, it will take some serious focal lengths to get much detail on it.

Attached is from the DSS2-red sky survey, image scale is 5 arc minutes on a side. That would put it just under 1 arc minute in diameter, although Hoag describes it as smaller:

"This object, which appears to be a perfectly symmetrical planetary nebula, was discovered on a 75-minute Jewett Schmidt plate. A perfect halo, 17" in radius, surrounds a diffuse central image." The Astronomical Journal, No 1186
