Modern observations

Hartung, E.J. (1968)

Hartung notes: "This planetary is a tiny bright ellipse about 8 x 6 arcsec in pa 0 deg; it lies in a Milky Way field well sown with small stars, and though very low for many southern observers, 10.5cm shows it."

Tom Lorenzin

Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "12.5M; 8" x 6" extent; very small and faint; very soft fuzz-ball at >300x; use N-filter."


(PK100-5.1) Mag=11.3. Lacerta: 22h, 23.9m; +50° 58' Since this object was not included in Luginbuhl & Skiff's handbook mentioned above, we were worried that it might not be easy to spot, despite the inclusion in Ferguson's table of objects found with his Questar. Yet Ferguson apparently noted its high surface brightness, since it was visible to him despite its 6" diameter. We found it indeed hard to locate. It was stellar-appearing (about 20" diameter) at low powers; the O-III filter helped isolate it in the starry field. Without the filter, it seemed to have about the same luminance as most of the stars nearby. Tenacity and patience -- and the oxygen filter -- will help in locating this challenging object.

Alldays (22.50S, 20.12E, 770m).

12-inch f/10 SCT (218x, 346x)

12th magnitude planetary nebula, which appears slightly oval at high power. Very tuff.. What amaze me more than the small out of focus dot was the long string of not less than 10 stars about 11magnitude in a N to SW direction about 7' towards the NW. Amazing. Difficult but grows with averted vision.
