Description:
I followed 56 and 61 as pointers to 81 Gem, then a little ways past this. At 32x I couldn’t tell much, at 48x was elongated, and at 72x cleanly split. Both members appear B to me. No attempt at measurement, but estimated the PA at 270° by slewing briefly in all 4 directions to get my bearings.
