This is a 3 image stack of three exposures 0.7 stop apart to enhance dynamic range using Photoshop.
Comet Leonard C/2021 is an easy spot with optical help in the evening sky but just outside my eye capability. This photo was captured in the fading Tucson light just above the haze layer. Might be a bit better by December 17th being higher in the sky near Venus and darkness arriving some minutes earlier.
