Every meteor of the night.

Drop in a video from a camera on a tripod. Meteor Cut finds every meteor with Sky Tracker, measures its speed, and cuts a highlight video with only them, plus pictures and tables. It all runs on this computer.

Choose a video, or drop it here MP4, MOV, MKV, AVI or WebM, up to the length of a whole night

Camera · optional, for speeds in °/s and km/s

Focal length (mm) Sensor or field of view (°) Tilt above horizon (°)

Without the lens, speeds are on-screen pixels per second. The km/s figure is the part of the speed across your view, so the real speed is at least that.

Time, place and stars · optional, for clock times, shower names and magnitudes

Video started at Latitude (° north) Longitude (° east) Plate solution (wcs.fits)

Identify the stars

{% if solver %}Finds where the camera pointed among the stars, so meteors get shower names, magnitudes and exact speeds, and the composite lines up on the stars. Needs a clear sky and a camera that did not move. {% else %}To identify the stars here, install astrometry.net (brew install astrometry-net) and run meteor-cut star-index. Or run meteor-cut sky-frame VIDEO, solve the picture at nova.astrometry.net and choose its wcs.fits above.{% endif %}
