The one that struck me the most is the ISS in front of the Sun - somehow that always gets me.
- agos 2y agoI've seen a couple of shots of the ISS in front of the Sun before - always very impressive, but man, the perspective on this one. Incredible photography
- rqtwteye 2y agoThat’s actually not that hard. You need a long lens. there are a few websites that tell you when the ISS crosses the sun in your area with exact time of the crossing. When the time comes, you set up your camera with a solar filter and do a burst for a few seconds. I have done it a few times and I am always surprised that it works. While taking the pictures you see nothing so you have to totally rely on the exact time. But it always works out. Same for the moon.
- hoseja 2y agoI was somewhat surprised at the scale. The station appears quite big compared to the sun's disk, doesn't it? These astronomical conjunctions are always useful when trying to internalize the geometry in the Solar system.
- gus_massa 2y agoRelevant xkcd https://xkcd.com/1276/ https://xkcd.com/1276/ in spite it doesn't have the ISS. The projection from the center of the Earth is 109m/(6380+408)Km*6380Km = 102m (336ft), similar to the projection of Neptune. But the angular size in your eyes maped to the Earth surface is 109m/408Km*6380Km = 1.7Km (1.0 mi) similar to the projection of Jupiter. For objects that are far enough both calculations are equivalent, but for the size in a photo I think the second is the relevant one.
- gambiting 2y agoIt reminds me of Outer Wilds(the video game).
