Open Cluster in Cassiopeia
NGC 581
Mag 7.4

Small and neat. 'Eiffel Tower' frames cluster

Quite compact Open Cluster in 12mm within a triangle of stars of which HIP 7232 at Mag 7.25 is the brightest and V1132 Cas, HIP 7282 at Mag 8.15 is at the other end of the base line
There is  a very orange star of Mag 8.50 within the triangle which sets it all off neatly!
