This image of NGC281 was created using 17x1200s Ha and 15x1200s OIII using a Skywatch 200 Newtonian telescope and an Atik 490 CCD camera. A synthetic green channel was created in photoshop. The OIII was taken last night with an 8nm Baader OIII filter and the Ha taken with a Astrodon 3nm filter a few weeks ago under full Moon.
