20 hours total exposure of NGC2170. It has a beautiful palette of colors due to multiple types of nebula. Dust particles reflect blue light, while red areas are emission nebulas. Ultraviolet light displays more magenta colors, and finally at the top center there are dark nebulas, mainly made of smoke, and since they do not glow on their own they are seen as silhouettes. To fit most of this region in the field of view this image is actualy two separate images stitched togeher. NGC2170 was photographed on several nights in March and early April, 2016. The image is still a bit noisy, meaning more exposure time is needed, but this area of the sky is now too low in the west. I hope to pick up more time for his image next year. This is an LRGB image in natural colors.
