What's New in SkyLumi
2.1.0
November 7, 2026
Save the telescope, eyepiece and camera combinations you use as setups. Switch between them with the new telescope button at the top right, or by tapping the setup chip on the sky. Turn the camera frame to plan your framing. Drag the dot on its edge, or type the angle in My equipment. The angle is counted from north through east, the way plate solvers report it, and the frame keeps it on the sky as the night goes on. Compare two setups on the same target, for example with and without a reducer. Pick "Compare with…" in My setups. The second frame is drawn dashed in amber, each frame has its own angle, and you can swap them or stop comparing from the small legend. Changing your gear now updates the frame on the sky, the setup chip and My equipment together.
