How to spot Chandra X-ray Observatory from Sydney

NASA's flagship X-ray space telescope.

  • Look in the direction listed — passes start near the horizon and arc across the sky.
  • Peak elevation matters — a 60°+ peak means it'll go nearly overhead; under 30° stays low.
  • Best viewing is in the 90 minutes after sunset or before sunrise — the satellite is sunlit while you're in shadow.
  • No equipment needed for bright passes — the ISS at peak rivals Venus.

Going to look up?

For fainter satellites you'll want 7×50 or 10×50 binoculars. A pair of Celestron SkyMaster binoculars is the consensus pick. Affiliate placement — replace with your affiliate link.
