Description:
NGC 281 shows its full beauty when observed with an OIII filter. Barely visible 
without the filter at 131x, NGC 281 turns into a showpiece with OIII filter. It 
has the shape of a sand dune (arc) and its extension is approx 20'x25'. A dark cloud intrudes the nebula from the SW. Averted vision shows several more dark 
filaments within the nebula. Very spectacular!
