The highlight of the evening was definitely the Cygnus cargo vehicle flyby, but I paid attention to the usual ISS imaging too. ISS came first and the flyby served as a test. The camera settings are the same that I have been using since discovering the correct values by experimenting. Once I saw the raw frames I estimated the settings for Cygnus.

Equipment:
Skywatcher 250/1200 Flextube dobson scope
Zwo ASI224MC camera
