Star trail (photograph)

 * ... that a long exposure photograph of the night sky can result in a type of picture called a star trail?


 * Hook seems pretty boring to me and anyway isn't directly immediately cited in the article. How about this? --Rnickel (talk) 16:45, 9 October 2012 (UTC)
 * ALT1: ... that star trail observations of Polaris have been used to measure the vibrations in telescope mounting systems?
 * I'm fine with this alternative. Let's see what others think.AstroCog (talk) 16:52, 9 October 2012 (UTC)
 * Other than figuring out the hook, the text seems good to go: Long enough, recent enough (assuming the "move from user space" date counts as the article creation date, right?), tone good. Only caviats:
 * no way to check for copyvio since all the refs are print.
 * I wasn't sure about the image... is it supposed to say "(pictured)" somewhere in the hook? Also I wasn't sure how to tell if it's public domain as required.

 * Can't help with print articles/books. I'm old-school, what can I say?
 * Image is public domain. If you click on the image, you'll see it's on the commons site, and has a public domain tag (image from NASA).
 * DYK rules say that the date of move from user space counts as creation date for new articles. Cheers, AstroCog (talk) 17:37, 9 October 2012 (UTC)
 * Symbol confirmed.svg GOOD TO GO, with ALT1 hook, but I would say as a text DYK, as the 100x100 pixel image does not work for that picture. Unless someone can be bothered to do a zoomed crop of the image and upload it?  Just a thought.   Geoffjw1978 TL C 22:50, 16 October 2012 (UTC)
 * The other images in the article also don't work well in 100px. I found this one in the commons: Circumpolar Star Trails With High Flyer.jpg
 * What do you think? Cheers, AstroCog (talk) 23:01, 16 October 2012 (UTC)
