Observer: Lew Gramer; Your skills: Intermediate; Date and UT of Observation: 1997-07-5/6, 05:30 UT; Location: Savoy, MA, USA (42N, elev 700m); Site classification: rural; Limiting magnitude: 7.3 (zenith), 16.5+ (20", 210x); Seeing: 3 of 10 - pretty good; Moon up: no; Instrument: 20" f/5 Tectron truss-tube dob Newtonian reflector; Magnification: 70x, 210x, 420x; Filters used: None; Object: ngc 6703, ngc 6702; Category: Non-interacting Galaxies [SA0-, E3:]; Constellation: Lyr; Data: mags 11.3, 12.2 sizes 2.5'x2.3, 1.8'x1.3'; RA/DE: 18h47m +45o40m;

Description: n6703, the brighter of this unusual pair of galaxies in Lyra, was surprisingly bright at 70x, with little detail. n6702 was found with some difficulty S of n6703, in the same 55' field. Averted vision was helpful in locating it amid the myriad field stars. At 210x, the diffuse halo of n6703 brightened rapidly to a bright core, which appeared to show a good-size "dust lane" or dark ark about 1' S of its center. n6702 was still barely visible in the same 20' field, making for easy comparison. It was roughly the same size as n6703. But unlike its putative partner, 6702 showed a quite elongated halo (ENE-WSW), with the elongation especially apparent in its moderately brighter core. At 420x, the "dark lane" in n6703's core disappears! Instead, the core at higher power appears slightly elongated NE-SW, with a mag. 13 star involved just on the S edge of the halo. Total apparent size about 2.5'x2'. n6702 actually seems fainter at 410x, with the bright core LESS apparent. Total size 2'x1'. It's interesting to observe the unusual: open clusters in Peg, planetaries in Vir, or in this case, bright galaxies in Lyr! [Telescope limiting magnitude was found using Luginbuhl and Skiff's photometric data for ngc 6802 in Vulpecula - handy!]
