New imaging project, the "Pickering's Triangle"

Last night was clear! I managed to get ~5h H-alpha exposures for the "Pickering's Triangle" in the Veil Nebula supernova remnant.

This is a dim target, I'll need additional exposures for this. Together, with S-II and O-III exposures, about 15 more hours is needed for a good signal to noise.
