ISS Solar Transit
I caught the ISS passing in front of the Sun again today, and didn't even have to leave my back yard! Thought I'd be clouded out but there was a partial hole just at the right time. A bonus was getting a sunspot (near the left edge of the Sun, AR2770), rather rare these days.
The geometry is such that the station is about as close as it gets, about 283 mi, so is relatively large, about 1/30 the angular size of the Sun's disk. The tradeoff is that it happens much faster than when it's farther away; the entire transit took less than a second. So I shot a movie to get as many frames as possible and combined individual frames for this composite.
Nikon Z6, Celestron C5 (1250mm, f/10), ISO 200, 1/5000 sec., tracked with an iOptron SkyGuider Pro. Post-processed in Lightroom and stacked in Photoshop. Time and location computed using ISS Transit Finder transit-finder.com/.
