"The California Nebula" (NGC 1499) (by William Gottemoller)

Congratulations to this week's StellarShot selection, which is a spectacular monochrome shot of the California Nebula by William Gottemoller. This image is made up of twenty-five 10min exposures, all taken through the rather-rare SVQ100 which was an f/5.8 quadruplet we made a very small number of. William was fortunate enough to have access to some very cool gear through his membership with the Milwaukee Astronomical Society. William's processing is superb and really does justice to this intricate target, which came out sharp, low-noise, and beautifully detailed. Thanks for sharing your work with us William, and we invite everyone else to please make sure you submit your own images to us directly by email, or by tagging them with #stellarvue and #stellarshot
