cúmulos luna llena


Almost full moon so of course a perfectly clear sky with all but the brightest stars on view. Give up? Had a go with the nice 6" reflector, one of Bresser's best. With a maximum exposure in moonlight of 2 minutes, this is the quite pleasant surprise. The sky is crowded around cassiopeia, so I did a bit of homework to nail 663 centre stage.
