OK, let's test this with an #astrophotography post.
This is my current #WIP: the Iris Nebula in Cepheus. So far, I've combined nearly 12 hours of 5 minute exposures to star revealing not just the beautiful reflection nebula in the center (dust reflects light from a relatively hot star), but the dark clouds of interstellar dust and cold molecular hydrogen.
I hope to push this past 20 hours of imaging over May and June. #Caldwell4 #NGC7023
