Description

I wanted to capture some dark nebulosity and practice getting the full dynamic range out of my pictures.   I really worked at stretching so that I didn't blow out my stars trying to bring forward the subtle variations in the background.   I could have sharpened around the cave nebula, but it is shrouded in a nebulous "fog" or haze, but I decided to leave it as I saw it.
