Roslund 5, an obscure open cluster consisting of stars of varying magnitudes, is 
located southwest of Gamma Cygni.  This large and sparse stellar grouping lies 
between Eta Cygni and 39 Cygni and is best seen with a binocular or a rich-field
telescope.  Using a 20mm Meade WA ocular with the 5" f/5 finderscope produced a 
very nice 32x view of Roslund 5.
