And now for something different! Eric Paulos on Capturing the Cosmos

Eric Paulos might be an EECS Professor at Berkeley, but his interests go well beyond computing and human-computer interaction. Eric recently wrote an article on Medium called Cosmos Caputring: Under the Hood (and Clear Skies). In the article, Eric discusses his long-lived interest in astronomy and how he has been satisfying this interest through his own astrophotography setup.

From the article:

When I do go out to image deep sky objects, I have a more dediated astrophotography setup. My latest images are shot using a Celestron Edge HD 8" Schmidt-Cassegrain telescope with a 2032mm focal length (and 8" aperture) making it F/10 (see image at top). It’s on an equatorial CGX mount that helps cancel the rotation of the earth to enable taking long exposures without star trails. I’m also using a ZWO ASI533MC Pro dedicated color astronomy CMOS camera cooled to -20C, a ZWO ASI290MM Mini guide camera on a 60mm guide scope, an electronic auto-focuser, and an ASI Air Pro (essentially a specialized Raspberry Pi for dedicated astrophotography) to manage everything. I always select targets before I go out to image for the night so I have a plan. I select objects appropriately positioned high in the sky (to avoid atmospheric disturbances) and up for long periods of time to allow the longest possible imaging opportunities.
