Description

Two clear nights in a row! Here's the HOO narrowband image of the Crescent Nebula NGC6888 in the Cygnus Constellation ...very faint in the lower left section of the image is the Soap Bubble Nebula, a planetary nebula; I was expecting to get a better result with the latter one, probably the passband (7nm) of the zwo narrowband filters is too wide for this faint object.
