Meade LXD75 8-inch f/4 Schmidt-Newtonian on a LXD75 mount using a DSI Pro 2 imager


The H-alpha image (combination of 480s exposures) and Red image (combination of 65s exposures) were meaned together before being combined with the Green image (combination of 65s exposures) and the Blue image (combination of 90s exposures). The exposures were taken on six different nights. PHD used for auto guiding and Nebulosity 2 for capturing the exposures. Images processed using AIP4WIN, DeepSkyStacker, PixInsight LE, and Nebulosity 2.
