Modern observations

Tom Lorenzin

Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11M; 9" x 6" extent; small, greenish oval is tough; use N-filter and high-x; 25' to NW is LP VAR FG SGE."

Birkmann, Mark [amastro]

Observer: Mark Birkmann Your skills: Intermediate (some years) Date/time of observation: 7/9/99, 6:00 UT Location of site: New Haven, Missouri (Lat N 38, Elev ~700') Site classification: Rural Sky darkness: 5 1-10 Scale (10 best) Seeing: 5 1-10 Seeing Scale (10 best) Moon presence: None - moon not in sky Instrument: 30" f/4, dob Magnification: 150x 540x Filter(s): Orion Ultrablock Object(s): NGC 6886 Category: Planetary nebula. Class: 2+3 Constellation: sagitta Data: mag 12.2p size 5.5" Position: RA 20h:12m 42.8s DEC +19:59' 22"

Description: Very small, no detail, color, or central star seen. Formed a triangle with two nearby stars, the nearest of which was an obvious yellow.

Steve Coe

Steve Coe, observing with a 13" f/5.6, notes: "Pretty bright, very, very small, little elongated. Just a central star with a tiny, elongated haze around it at 220X. The grey-green color gave it away. Camp 613 13" 330X--pretty faint, very small, not brighter in the middle, round, just barely larger than seeing disk, on east side of isosolese triangle of stars of equal magnitude."

AJ Crayon

AJ Crayon, using an 8" f/6 Newtonian, notes: "is a planetary nebula. It is about the size of the seeing disk 12m and round, at 200X. This was a very difficult object to find."

Contemporary observations

Pietersburg

16-inch f/10 SCT (95x, 127x)

Conditions: Good

I could only see it in 290x as a frosted greenish spot which is out of focus compare to the two similar brightness stars which form a tri angle to the planetary. The spot could be very very slightly elongated in a NW-SE direction but it could be illusion as well, difficult. The SW star of this trio is deep yellow in color.

Sky Conditions:The fainter parts of the Milky Way are barely visible on the horizon.

Transparency of the Sky:Haziness only visible on the horizon.
