This is a luminance image of IC443, created by collecting and stacking 19 x 240s exposures through a red Astrodon filter. The exposures were collected between 01.00am and 02.20am on 26th November 2017. Simon used an Atik 460EX at prime focus on an 8” F4.5 Orion Optics CT8 reflector. Stacking was carried out using Nebulosity with post processing in Photoshop. The nebulosity was barely visible through a clear luminance filter of 60s length, hence his decision to collect the luminance through the red filter.
