Ow, shooting the sky, I understand. You have to have a camera with the lowest noise at high ISO, the A7s is a good choice for that, according to snapsort.com server measurements (http://snapsort.com/explore/best-digital-cameras/2300-iso-low-light-48-months-recent). And high megapixels, of course. For good night shots with Powershots I had to use the 15 sec shutter speed (firmware maximum) and raise the ISO virtually by multiple captures, then blend the images into one, for the lowest noise. But due to Earth rotational speed you probably cannot use that technique. I would say all the USB webcams out there have far worse optics (noise and picture), than the cheapest compact camera, unfortunately. Cheap plastics lens, crappy noisy sensors. There are few exceptions, indeed, for ex. the latest Logitech webcams with a fine Carl Zeiss optics, but again, the price is 10 times higher than old Powershot SX100, and the noise/ISO level is unknown. So it's really a hard choice to find something reliable without spending hundreds $s. On the other side - if the SX100 will break after 100 000 shots, I will replace it for another $20 piece quite happily ;) ----- ------------ Czech Republic -- View this message in context: http://gphoto-software.10949.n7.nabble.com/Shutter-lifetime-tp16567p16574.html Sent from the gphoto-user mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot
