I listen to lots of science podcasts while imaging, especially ones from the BBC, The Guardian and Nature; thus my kit comment. Above is the setup just after taking flat frames for the coming night session. Celestron 8, Celestron AVX mount, ZWO ASI294 MC Pro color camera, Starizona Night Owl 0.4x Reducer/Corrector and Orion Magnificent Mini Auto-guider, For power, partially hidden by tripod leg, a Westinghouse iGen160s. Also available a 12v Centech jump starter. During twilight the auto-guider is temporarily swapped for a 50mm visual finder to do the all star polar alignment. Then the auto-guider is swapped back in, wired up and calibrated using stars near the celestial equator. Update: The Centech is no longer used. The iGen160s has more than enough juice to handle all the night's power needs.
