Bad Image Examples

This lesson provides multiple examples of poor-quality images and explains both the reasoning behind the results and some of the specific cases in which they may still be of use.

Seeing

Seeing is an important concept that describes how clear an image's subject is when viewed through the Earth's atmosphere.

Earth’s Atmosphere

A severely limiting obstacle, the Earth's atmosphere must be well understood and carefully considered when working in the field of astronomical imaging and science.

Image Reduction – Overview

Image processing goes through pre-processing (calibrating images using darks, biases, and flat-fields) and post-processing (When images are digitally reduced: WCS Coordinates, removal of Cosmic Rays, Transformed, etc)

Airmass

Airmass is the path length for light from an astronomical object to pass through the Earth’s Atmosphere, and a greater airmass means dimmer targets
