I Used 2 Telescopes Yesterday Morning to Capture the ISS Transiting our Moon in High Resolution.

I captured this image from my home in Washington, USA, on 12/31/25 at 1:11AM. I used a Celestron 9.25” telescope with a ZWO ASI662MC and a Celestron 5SE with an ASI294MC together to capture the event.

This is a picture I’ve wanted for years, and what better way to end 2025 than by finally getting the shot!

The International Space Station moves so fast that this whole event lasted only 1 second. Thankfully, by setting the camera exposure to a mere 1 millisecond, the ISS details can be seen clearly.

Equipment/Settings: C9.25, ASI662MC, C5, ASI294MC, IR685nm filter / UV/IR cut filter. 1ms exposure, 150 gain for the C5 and 250 gain for the C9.25. 90 seconds stacked on the cropped images, 60 seconds stacked on the full disk.
