The pacman nebula, NGC 281 in Cassipea last night.
Real high in the sky around 11pm. Two hour exposure.
Notice the globules in the upper left section of the nebula.

The bubble nebula in Cepheus from tonight clear sky and last sunday. Three hours through H-alpha.

Three hour expousure in H alpha last night. Here hot OB stars associations light up this  molecular cloud, Cederblad 214. This is one of the largest molecular cloud complexes in the Milky Way.  Stellar winds and supernovae driven shock fronts produced by the hot OB stars of the association have expanded an immense 200 light year diameter shell of molecular gas which contacts the surrounding cold molecular cloud.

The pelican in Cygnus, last night.  Wide field two hours exposure at f5 through a 5" refractor.

Central section of the veil nebula. One hour exposure.
The Veil  is a supernova remanent. It exploded some fifty thousand years ago. The filaments are a shock wave that is expanding in a dusty region, clearing it as it goes. Notice that many faint stars are visible at the bottom where the dust has been cleared than at the top.

NW section of the Veil Nebula, a supernova remanent in Cygnus. High overhead this autumn evening. Six ten-minutes guided exposure combined for a total on one hour.

The mexican section of the North America Nebula. Taken last night through somewhat hazy skies. One hour exposure (six exposures of ten minutes each.) Cygnus, where the nebula is located, was getting low in the West..... summer is over and fall is here.

Pelican nebula monochrome h alpha filter.

Crescent nebula in Cygnus last night just past full moon. Two hour exposure (12 ten minutes exposures) tak toa 130 sxvh9 starlight express camera.

Jupiter this September evening shot through H-alpha narrowband filter.
Prime focus through C-11. Combination of 220 exposures of 0.3 seconds each.
In the seventy seconds or so of the exposure, the moons Ganimede, Europa (Jupiter) and Io moved enough to show visible trailing.
