NGC281 in Cassiopiea
with 10" f/3.9 Astrograph
Uploaded 11/86/21

 
Surrounding
            the open cluster IC1590, this well known object has so much to
            show in deep exposures. A dark bar of dust blocks out the central
            region below the star cluster, and just around the clusters hot
            stars the UV radiation imparts a magnificent pink coloration
            to the core of the nebula, fading to deep crimpson reds in the
            extremities.
