Stars are usually focused manually. The infinity mark on most lenses deviates somewhat from true infinity, so it's best to focus manually using a bright star on the rear screen. Turn on the camera's live view, zoom in, find a fairly bright star (or a distant light, or the moon), and slowly turn the focus ring. When the star shrinks from a blurry disk into a crisp point of light, focus is nailed."},{"t":"h","x":"欢迎关注@Thomas看看世界，每周学会一个摄影技能。","xe":"Follow @Thomas Chu Photo, and learn one photography skill every week."}],"titleEn":"Astrophotography Video Tutorial: Shooting the Milky Way on Snowy Glaciers"}
