Corwin's Notes
=====
NGC 2020 is a fine annular nebula, either a supernova remnant or an HII
bubble. JH's position applies to the brightest part of the annulus west of
the center. My own preferred position is for the center of the annulus since
JH says in both of his observations that the nebula is 4 arcmin across. To
make it that large, we need to encompass the entire annulus and more.
Steve's Notes
=====
NGC 2020
30" (11/5/10 - Coonabarabran, 264x): fairly bright, roundish annular emission nebula, slightly elongated SW-NE, 3'x2.5'. The inner edge of the annulus is slightly brighter and sharply defined with a relatively large dark center, ~45" x30". North of center in the ring is a 13th magnitude star, which appears roughly centered in the emission nebula. A 12th magnitude star lies 1.3' S of the central star, at the southern edge of the nebula. Two fainter stars are just north and south of the mag 12 star and the trio is collinear with the central star. Forms a striking due with NGC 2014 (cluster and emission nebula) 5' WNW. The remarkable Seagull Nebula (NGC 2030, 2032, 2035) lies 15' NE.
