Notes: Set D7100 to complete manual mode including manual focus. Set the Nikno to take 20 second exposures and the intervalometer to take an exposure every 23 seconds. Attached lens muff with handwarmer to lens to counteract dew.
Let the D7100 take images all night and then reviewed the images in the morning. Selected the images with obvious meteors for processing.
