| Comment | Just before the moon rise, naked eye visible with averted vision (SQM 21.94), color light blue-green visible through my 2x16mm EP close to globular cluster NGC 5466 (mag 9.04) less brillant than M13 but clearly greenish in comparison, larger and more condensed. 2 tails visibles plus syndyne inbetween, ion queue = 40' with SWAN filter, dust one = 23' length. A sketch will follow. |
