Personal "rating" this aperture: B/B+
I love this object every time I see it. An annular ring with nebulosity
throughout. Pronounced central star but best observed at higher power
(about 150x and above) and averted vision. Central star really takes
over the show and pops out once clearly detected, and once
it IS detected in fact, it dominates the nebula. (Unlike M57)
However, NGC1501 is best viewed without filtration and without the binoviewer
although it (the central star) did show up with the binoviewer used at
264X with no filter. It also does barely shine through at 223x with
a deepsky filter. UHC filter brings out the nebulosity best, but at
this aperture, I lose the central star.
