Abell 39

 

Abell 39, PK 47+42.1. 2020-07-17, Cherry Springs (elev. 700 m), SQM 21.6. 20-inch Newtonian (F/4). Ocular 13 mm. Fairly large, round, almost annular, nebulosity extends to the central star, edge well defined, second star embedded just inside the enhanced edge on the S side. Similarly faint star is immediately off the SE edge; a brighter star is close to the W edge. The edge is particularly enhanced on the SE side.

Abell 71

 

2020-07-15, Beaver Meadow Observatory, SQM 21.19. 20-inch Newtonian (F/5), 13-mm ocular, OIII filter. Abell planerary nebulae. Abell 71, Cyg. An annulus, star embedded in the void off-center to the NW. A close star pair immediately off NE edge, a wider pair of brighter stars immediately off SW edge. E side of the annulus is much brighter. Inner edge soft, outer edge well-defined. The annulus is almost interrupted on the NW side next to the interior star. The faint double between the brighter stars to the N is cleanly resolved. PK 85+4.1.
