A wide field view of Sagittarius messier objects using a 100mm fl Canon lens on a T3i camera, riding piggyback on my 14.5" Zambuto Starmaster Dobsonion with Skycommander Goto and Tracking. Visible objects include m16, m17, m18, m20, m21, m22, m23, m24, m25, and perhaps others. Barnard objects are also present, especially the dark cloud B92. Online reports say this one convinced Barnard that such dark areas aren't absence of stars, but actual dust objects obscuring starlight from our view.
