Astrophotography with the Meade 127ED APO Refractor and the Canon EOS 10D DSLR Camera



M42 - The Great Nebula in Orion, by Ashley Stevens


 [M42 - The Great Nebula in Orion]

10 minutes guided photograph of M42 - The Great Nebula in the "Sword" of the constellation Orion.
Combined with a 1 minute exposure to bring out details in the "Trapezium" region.
Slightly corrected to improve contrast and enhance color. Sharpness slightly enhanced with Photoshop "unsharp masking". Taken in January 24 '04, 23:10 EST, from Mahogany Hammock, Everglades National Park, Florida, USA.

North is to the top, East to the left of the photograph made with a Canon EOS 10D DSLR camera at ISO 400 at the focus of a Meade 127ED 5" f/9 apochromatic refractor, F.L. 1,143 mm, on a Meade LXD650 German-equatorial telescope mount.

The image above is a reduced (1/4 size) and compressed JPG version of the original photograph.

The very bright stellar region near the center of the photograph is the "Trapezium", the stars that light up the nebula from within. There are 4 bright stars forming the Trapezium, 2 of them have much dimmer companion stars. These 6 stars are visible with a small telescope, about a dozen stars with a medium telescope.

Astrophotography with the Canon EOS 40D DSLR Camera




The Winter Milky Way East of Orion, by Ashley Stevens


 [The Winter Milky Way East of Orion]

North is to the left, West to the top of the image, made with a Canon EOS 40D DSLR camera at ISO 800 and a Canon f/4L 17-40 mm zoom lens at 17 mm f/5.6, on a Meade LXD650 German-equatorial telescope mount.

The very bright star near the center of the image is Sirius, in Canis Major, the brightest star in the sky.
To the Northwest there are 3 aligned bright stars forming the "Belt" of Orion. The "Sword", with M42 - The Great Nebula in Orion, can be seen to the South of it. The orange star Betelgeuse can be seen to the Northeast of the "Belt", Bellatrix to the Northwest and Saiph to the Southeast (Rigel, to the Southwest, is not shown).
To the Southeast of Betelgeuse and Northwest of Sirius is the bright "Rosette Nebula", in Monoceros.
To the Northeast of Sirius is the bright star Procyon, in Canis Minor.
To the South of Procyon and East of Sirius are the bright Open Clusters M46 and M47, in Puppis.


Photographic mosaic of the Winter Milky Way in Orion, Canis Major, Canis Minor, Monoceros and Puppis; 4 frames of 10 minutes each, taken in February 5 '08, around 23:30 EST, from West Summerland Key, Florida, during the "2008 Winter Star Party". Sky conditions: clear, dark sky, good transparency.
