Nebula

Located 1500 light-years from Earth, the Great Orion Nebula (M42) presents a cross-section view of a galactic bubble of gas and dust.

M20 is a cloud of ionized hydrogen gas some 25 light-years in diameter. Dark lanes visible in 3-4 inch telescopes may be seen extending from its center towards the west, northeast, and southeast, effectively dividing the nebula into 3 distinct patches, hence the name ‘Trifid’ which means ‘split into three,’ was derived. M21, an open cluster, is also visible in this photo (upper left of the nebula). Sky-Watcher 100 ED 4 in f/9 refractor, Kenko NES mount, Canon 450D DSLR, 240 sec exp, IS0 1600.

M8, the Lagoon Nebula, is a cloud of ionized hydrogen gas some 50 light-years in diameter, located about 5000 light-years away. It is a region in space where new stars form. To the east of the nebula is the open cluster NGC 6530, also visible in this photograph. Sky-Watcher 100 ED 4 in f/9 refractor, Kenko NES mount, Canon 450D DSLR, 2 x 240 sec exp, IS0 1600.

M57, the Ring Nebula, is a planetary nebula in the constellation Lyra. It is a cloud of cold gas expanding away from a small hot central star that provides energy for the gas cloud to glow. The nebula is relatively easy to find and is visible even with 3-4 inch telescopes. Sky-Watcher 100 ED 4 in f/9 refractor, Kenko NES mount, Canon 450D DSLR, 10 x 60 sec exp, IS0 1600.

M27, the Dumbbell Nebula, a planetary nebula in the constellation Vulpecula imaged using a Sky-Watcher 100 ED 4 in f/9 refractor, Kenko NES mount, Canon 450D DSLR, 5 x 90 sec exp, IS0 1600. April 5, 2012, Camarines Norte, Philippines. Photo Credit: Anthony Urbano
California nebula
Wide-field image of the California Nebula (right) and the dark nebula beside it (left) taken with a Canon 450D DSLR and a 50 mm f/1.8 kit lens, ISO 1600, 12 x 20 sec exposure, on November 11, 2012 under the dark clear skies of Boso-boso, Rizal, Philippines. The low surface brightness of California Nebula makes it an extremely difficult target to observe visually, but shows up nicely in photos. Photo Credit: Anthony Urbano
Veil Nebula
A 30-minute exposure with an OIII filter shows the fine thread-like structure of the Veil Nebula, a supernova remnant in the constellation Cygnus. The narrow-band filter helps cut through the severe light pollution in the city. Sky-Watcher 100 ED 4 in f/9 refractor, Kenko NES mount, Canon 450D DSLR, 4 x 480 sec exp, IS0 1600. April 15, 2012.

    • Feel free to browse the article here. Take note though that this project was done several years ago, and there are far better ways of building similar projects now (e.g., using ‘GPUSB’ instead of the obsolete parallel port or perhaps using Arduino).

      • Wowww..I think I’ll pass on that, I’m not an electronic guy as you :)
        BTW, I only have a Canon 6D right now and I’m on the way to purchase an Astro Tech AT65EDQ as my first scope. Do you think I will be able to capture the Orion Nebula without EQ mount, tracker, or auto guider? The setup will be like this:
        ISO 3200
        Sub 300x1sec
        Dark frame 20
        Bias frame 10
        Stack with DSS
        What do you think? Ohhh…does DSS has aligment feature so there will be no star trail in the stacked image?
