Nebulas

Rho Ophiuchus Nebula Complex and interstellar dust clouds. Located in the constellation Scorpius.
The orange star in the center is Antares. Canon 7D Mark II, 100mm f2.8, 34 one minute exposures
stacked in Deep Sky Stacker.  Tracked with iOptron SkyTracker.

The Great Orion Nebula. Full frame, 500mm, single two minute exposure.

Horsehead Nebula and the Flame Nebula. 500mm, single two minute exposure.

Bubble Nebula and M52 (a star cluster). 500mm, f4.5, ISO 800, about an hour of integration.


Pacman Nebula, NGC 281. 29 one minute exposures at 500mm, f4, ISO 800.
Tracked with an Astrotrac, camera H-alpha modded Canon 7D MII.
I had over 60 subs but the wind ruined half of them. It turned out OK despite that.


Lagoon and Trifid Nebulas, located in the constellation Sagittarius.

The Heart and Soul Nebulas and the Double Cluster. Zeiss 135mm f2 Sonnar, Canon 7D M II
(H-alpha modified), 800 ISO at f2.8, 66 one minute exposures, stacked in Deep Sky
Stacker, processed in Images Plus and Photoshop, tracked with AstroTrac.


California Nebula.
Fifty-five 60 second exposures, f3.5 @ 800 ISO, Canon 7D M II (H-alpha mod), Canon
200mm f2.8 lens. Tracked with an AstroTrac. Stacked in Deep Sky Stacker and
 processed in Images Plus and Photoshop.


Barnard's Loop, a large nebula in Orion, this also includes the Orion Nebula and the Horsehead Nebula.
Twenty-five one minute exposures, stacked in Deep Sky Stacker, Canon 7D Mark II, 100mm f2.8.


Eagle Nebula. The nebula is about 7000 light years from Earth.
The Pillars of Creation can be seen in the core.
The pillars alone are several light years in length.

The Dumbell Nebula, a planetary nebula. 700mm, tracked with an AstroTrac.

The Helix Nebula. This planetary nebula is only visible in the far south at this latitude (43 N). I wasn't sure if it was going photograph very well being so low (about 20 degrees) on the horizon, but it came out pretty good. Fifty-one one minute exposures, ISO 800, 500 mm, f4, tracked with AstroTrac. Processed in Images Plus, stacked in Deep Sky Stacker, final processing in Photoshop. This is nearly full frame, slight cropping along the edges.


North America Nebula

The Owl Nebula (M 97) and the Surfboard Galaxy (M 108), in Ursa Major, near the star Merak.
The Owl Nebula is a planetary nebula.

The Veil Nebula and Filamentary Nebula, the remnants of a supernova. I really need a camera modified to capture hydrogen-alpha light, that would show a lot more red filaments. As it is, I had a difficult time even getting this, and it is
over processed to bring out the faint nebula. The bright star in the upper left is Gienah, in the constellation Cygnus.
