This image of IC5146 was captured using the coma corrected 500mm Newtonian at COAA by myself and Dr. Bev Ewan-Smith.  All calibration and processing was carried out using PixInsight.

We actually captured the image over the nights of 15th and 16th of August.  104-minutes of total exposure (43 frames) were selected for the final integration into the image.

IC5146 appeared invisible in the eye-piece.  The camera however, reveals the mixture of emission nebula, reflection nebula and dark nebula in this beautiful stellar nursery.
