Lynds Dark Nebula 6732250 viewsLynds Dark Nebula 673 is found in the constellation Aquila. Unlike bright emission or reflection nebula, dark nebulae are essentially a dense cloud of gas and dust particles that block the light of stars behind it from our view. In this case, the light of stars in our Milky Way galaxy is blocked from view. Stars that do shine through often appear red due to the scattering of light by the dust particles. Total exposure of the image is 3.5 hrs (42 x 5 min).
The Eagle Nebula1611 viewsThe open cluster Messier 16 and the associated nebulosity IC 4703 are found in the constellation Serpens Cauda. The popular name of this object is the Eagle Nebula, and contains the "Pillars of Creation" that was made famous in the image taken by the Hubble Space Telescope. This image was a total of 3.5 hours exposure (21 x 10 min subframes) taken with a modified Canon 40D and a Takahashi Epsilon-180ED.
The Cat's Paw Newbula1460 viewsNGC 6334, AKA the Cat's Paw Nebula, is found in the constellation Scorpius. NGC 6334 is a complex emission nebula along with dark dust lanes. Image is a total of 3 hours 25 minutes exposure (41 x 5 min) taken with a modified Canon 40D and a Takahashi Epsilon 180 f/2.8 astrograph. Image was processed using Images Plus 3.82B and Adobe Photoshop CS5 software.

Hydrogen alpha image of Messier 81425 viewsM8, an emission nebula, is found in the constellation Sagittarius. A significant portion of it's composition is hydrogen, which emitts light due to the excitation of the hydrogen atoms from radiation coming from the embedded stars in the nebula. A particular wavelenght of this emission, Ha, was imaged using a narrowband filter and assigned a red color (TeleVue 85 refractor; 0.8 reducer/fattener; SBIG ST-2000 CCD; 25 x 5 min lights; 30 darks; 41 flats).
IC 1275 and NGC 65591316 viewsIC 1275 and NGC 6559 lie in our Milky Way galaxy in the constellation Sagittarius close to Messier 8. This complex area of both emission and reflection nebulosity also includes IC 1274, IC 4684, and IC 4685. The image is a total combined exposure of 1 hr 25 min with a Takahashi E-180ED astrograph and a modified Canon 40D on a Paramount. Processed using Images Plus and Adobe Photoshop.
Supernova in Messier 1011293 viewsA supernova has appeared in the galaxy designed Messier 101. A supernova is essentially a star at the end of its lifetime that has exploded. This particular type of supernova is a type Ia, which is assumed to be due to the destruction of a white dwarf in a binary star system. The supernova can be seen in the image as the brightest "star" within the galaxy; located to the left of the center of the galaxy.
Gibbous Moon1245 viewsA picture of our nearest neighbor, the Moon, taken on Oct 7, 2011 with an Astro-Physics 178 mm f/9 refractor with focal reducer @ f/7.1, 1262 mm focal length; Modified Canon 50D; AP 1200 mount; 26 x 1/125 sec lights (best of 31 images graded in Images Plus 4.25); 31 darks, 66 flats).
NGC 6559, IC 1274/75, and IC 4685 region in Ha1216 viewsThe IC 1274/75, IC 4685 and NGC 6559 complex imaged in Ha are located in the constellation Sagittarius (visible light photo previously posted). Just to the right of NGC 6559 (the brightest emission nebulosity slightly below left of center in the image) in the large HII region IC 4685 is the serpentine structure of the dark nebula Barnard 303. Total exposure 1 ½ hours (TeleVue 85 refractor; SBIG ST 2000 ccd camera @ -13 degrees; Paramount; Baader 35 nm bandwidth Ha filter; 30 x 5 min lights; 35 darks; 41 flats).
Messier 271164 viewsM 27 , aka the dumbbell nebula, in the constellation Vulpecula was discovered by Charles Messier in 1764. M27 is a large cloud of expanding gas, which is the remains of a star that expelled its outer atmosphere near the end of its lifetime. M27 is a bright object that can be seen in binoculars and is a favorite telescopic object in the Spring and early Fall. Total exposure of 1 hr 40 minutes (20 x 5 min lights;30 darks; 66 flats; AP 178 f/9 refractor; Modified Canon 50D; AP 1200 mount; guided exposures)
Messier 8, 20, and 211112 viewsThe Messier objects M8 (large nebula on right), M20 (blue and red nebula upper left) and M21 (open cluster below and to the left of M20) are favorite summer objects in the constellation Sagittarius. The Messier objects are found in a dense star field of our own Milky Way galaxy. Image taken with a modified Canon 40D and Takahashi E-180ed astrograph on a Paramount (50 x 5 min lights; 30 darks, 64 flats).
