The Iris Nebula in RGB

NGC7023 Imaged over two nights and plagued by satellite trails. Imaged before moon rise on Monday 29th and Tuesday 30th nights. Exposure times were 8x 900s in Red 8x 630s in Green 8x 820s in Blue. Tricky one to process, pushing it so close to the noise levels really brings out faint gradients. Processed in Photoshop.
