The Crescent Nebula ( Ngc 6888) : HOO-RGB Blend

 One of the last targets I managed to image before I left good old US of A. This image was captured at the Eldorado Star Party of 2018. The extremely dark skies of Texas really helped me to get the fine O3 nebulosity details in this nebula. The image has a total integration time of under 15 hrs. RGB stars were added after the HOO blend was accomplished using a modified PixInsight script.
