Here’s the capture from my backyard, at actual speed and 25% speed. Also visible is sunspot AR2833.
Since the angular size of the ISS was only predicted to be 35 arc seconds, I opted to use my portable setup which consists of a Fornax LighTrack II mount, a Canon 100-400mm lens with a 1.4x Extender, an Astrozap Baader solar filter, and a ZWO ASI174MM camera. The capture software was SharpCap and the camera settings were RAW16, 1920×1080, gain 0, and exposure 0.45 ms which produced a frame rate of 89 fps.
For anybody who doubts the accuracy of the Transit Finder predictions, look at the following statistics:
The actual transit duration was 0.971 seconds
