My favorites so far are the Orion Nebula, the M78 NGC2071 NGC2064 NGC2067 Nebulas, Horsehead, Flame and Veil Nebulas, and the Andromeda Galaxy.
I'm surprised that you get get images of this quality from the ground with an 8" telescope. I guess image stacking and other contemporary technical advancements have made this possible. I thought this image quality required the likes of the Mauna Observatory in Hawaii or the Hubble telescope. I must simply be out of touch.
These are beautiful images; thanks for sharing.
