Just wondering if I have a chance at bagging this planetary with my 15 inch dob. Has anyone seen it with this aperture? Am I wasting my time? Thanks Raul

I have seen it in my 48" reflector. As we say here "give it a go" with your scope and let us know! All observation are welcome Positive or negative. Good Luck!!

Seeing it should be no problem for your 15 inch. Splitting both knots is another story.

In my PPN project (http://www.deepsky-visuell.de/Projekte/PPN.htm) I wrote:

24", 687x, fst 7m5+, seeing III
bright central part already visible in the searching magnification; with higher power the central area seems to be slightly diffuse without showing the faint extensions

28", 1248x, fst 7m5+, seeing I-II
direct vision object; with high power two separated, 1:2 elongated parts; divided with a small dark lane; both extensions similar long and bright; a brighter knot sits directly NW over the dark lane in the NW part
