Untracked Exposures: Star Drift by Declination, Pixel Trailing & Star Trails
This lesson is part of the course
In this lesson
You calculate how fast stars drift across the sensor at six declinations, turn an allowed trail of a few pixels into a maximum exposure time and plan a two-hour star-trail sequence by arc and frame count.
