ST4 Img Exp Calculator Question
#2
Hello Ed,

When you choose to expose for a generic option, such as "Galaxy," the surface brightness is calculated for a typical galaxy.

When you choose to expose for a specific target object, which is a galaxy, the surface brightness is calculated for that specific galaxy, taking into account its integrated magnitude, size, and Hubble class.
Clear skies,
