= Jones 1 (~N7710)

15cm - vsl brtning in area @ 80x w/o filters. both UHC & [OIII] effective, the [OIII] the more so; even the DS filter helps. not much to enhance, though. better @ 50x due to lg size. complete annulus w/thin rind; brtr knobs at pa170 & 350 bulging on inside of rim; brtst is Srn one, which has some f *s S of it. ring vwk on Ern periphery. fld mod *ry, but no cen * to mv~13.5. BS, 19Nov1989, Anderson Mesa.

Tom Lorenzin

Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "12.1M; 6' x 5' extent; very large, very faint, annular haze; resembles a smaller, fainter Helix (N7293); requires great transparency and N-filter; use field motion to detect; 50' SSE of 5M 72 PEG; the name "Jones 1" is also confusingly applied to PK 164+31.1."

Steve Coe

Steve Coe, using a 13.1" f/5.6, notes: "Jones 1 (PK 104-29.1) Very faint, very large, irregular. This tough planetary was only seen with the UHC filter installed. It has a "Quarter Moon" or "C" shape at 100X."
