Original mosaic was 11,440 x 2,800 pixels.<\/p><\/div>\n<p><strong>Field Work<\/strong><\/p>\n<p>I shot this in Scotland in October using only a fixed tripod and a Canon 1100D with the stock 18-55mm lens. At this time of year, the Milky Way passes close to\u00a0the zenith which makes this method easy to use. You could adapt it for other dates by tilting your tripod head so that it follows the Milky Way as you tilt the camera.<\/p>\n<p>First, get to a dark site with clear views of the Milky Way from horizon to horizon. Set your tripod level and take some test shots to test focus and exposure. I set the lens to 18mm, wide open aperture, ISO 6400 and exposure to manual at 30sec.<\/p>\n<p>Now aim at where the Milky Way crosses one horizon and take your first shot. Tilt\u00a0the camera up about 15 degrees and take another shot. Repeat until the camera is pointing straight up which should give you a series of 7 shots or thereabouts. (The angle is not too important &#8211; you just need a good overlap between shots. Now turn\u00a0your camera round to the other horizon and repeat for a second series.<\/p>\n<p>Shooting all the images took me about 10 minutes.<\/p>\n<p><strong>Create\u00a0the Mosaic<\/strong><\/p>\n<p>I used the amazing and free <a href=\"http:\/\/research.microsoft.com\/en-us\/um\/redmond\/projects\/ice\/\">Microsoft Image Composite Editor<\/a>\u00a0(ICE) to stitch the mosaic. Start by loading the first series of images (I used the raw .cr2 files). Then click\u00a0Stitch and select the Transverse Mercator projection when it has finished stitching. Click Crop and then No crop and then click Export and select the .PNG image file option. Click Export to disk and select where to save your first half of the Milky Way. Repeat for the second series of images which will give you 2 mosaic halves like these.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-651\" src=\"http:\/\/starrydave.com\/wordpress\/wp-content\/uploads\/IMG_5498_stitch-no-crop.png\" alt=\"IMG_5498_stitch no crop\" width=\"400\" height=\"647\" srcset=\"http:\/\/starrydave.com\/wordpress\/wp-content\/uploads\/IMG_5498_stitch-no-crop.png 400w, http:\/\/starrydave.com\/wordpress\/wp-content\/uploads\/IMG_5498_stitch-no-crop-185x300.png 185w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-650\" src=\"http:\/\/starrydave.com\/wordpress\/wp-content\/uploads\/IMG_5491_stitch-no-crop.png\" alt=\"IMG_5491_stitch no crop\" width=\"400\" height=\"660\" srcset=\"http:\/\/starrydave.com\/wordpress\/wp-content\/uploads\/IMG_5491_stitch-no-crop.png 400w, http:\/\/starrydave.com\/wordpress\/wp-content\/uploads\/IMG_5491_stitch-no-crop-182x300.png 182w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><\/p>\n<p>You can now use ICE to join these 2 halves to make a complete mosaic.
