This is a redo of the eastern sky the earlier had cloud cover and light noise from street lights. This time I had a clear night and I elevated the camera to about 65 degrees above the horizon to reduce light noise. Camera used was a GoPro Hero 4 Black with a 7.2mm lens.

Dwayne Kellum Published on Dec 15, 2018 High Altitude Balloon 17 Launched from Santa Nella, Ca. on 26 Oct. 2018 at 13:17 PDT. Landed Northeast of Firebaugh, Ca. 26 Oct. 2018 at 15:55 PDT. Maximum Altitude 96,225 Feet. One Camera onboard GoPro Hero 4 Black with a 5.4mm Lens. Goal, Test new cut down procedure. Here is something interesting that I didn't mention in the video. The temperature swing. At launch the Temperature was about 87 degrees F. The coldest temperature recorded during accent was at a altitude of about 50,117 feet GPS with a temperature around -35 degrees F. Than the temperature started warming back up to a temperature around 23 degrees F at burst altitude 96,225 feet. The temperature started dropping as the capsule approached 53,000 feet Barometric the GPS wasn't working correctly because it lost its lock. The temperature bottomed out around -40 at this time. The temperature began to rise again the closer the capsule got to the ground. My data logger failed at about 50,000 feet so I don't know what the temperature was at landing site but temperature was in the 80's that day. When the data logger failed towards the end of the flight I used the data recorded from my radio tracker, that device dose not record temperature and the last track I got from that device was a little under 900 feet.
