I had planned to use another of my older telescopes this night but it was too windy. I did set up a camera tripod with the Levenhuk Smartphone Adapter on the observatory patio so that I could photograph a low elevation pass of the International Space Station (ISS) using the iOS app NightCap Camera.


Just prior to the ISS pass starting I decided to move the tripod and iPhone to the northwest of the observatory to capture the Space Station over the observatory dome. I took this photo using NightCap Camera (ISO 1000, 1/2sec, 1X lens) showing Venus and Saturn just above the dome.

Shortly after the ISS became visible in the western sky I started the NightCap Camera "ISS mode" for this photo (ISO 1600, 1 second exposures, 132 seconds duration, 1X lens). Stars and the planets are trailed since I did not use a tracking mount. The ISS was moving to the left in the photo (West to South).


Due to the wind I ended the session.
