Could not resist as it was so clear and cold took sixteen frames of the Lagoon and Trifid with better framing.
Details.
Canon 5DH, Canon 300mm F2.8L at F2.8. Hutech LPR filter, 16X240sec ISO 400, in cam noise reduction ON, processed with ImagesPlus and RegiStar.
Warning 3.5MB because it is worth it. The original is a 15MB JPG.
