Vega_Betelgeuse_spectra.jpg
A Tale of Two Stars909 viewsHere are basic spectra from two familiar stars in the night sky. Vega's spectra is on the left and basically has weak spectral lines based mostly on the Hydrogen Balmer series. This is indicative of a fairly young, hot star. Betelgeuse's spectra is far more complex. We can see spectral lines for Barium, Calcium, Iron and Magnesium and compounds like Vandium Oxide and Titanium Oxide indicative of a star near the end of its life. Data collected with amateur equipment and processed through RSpec software.
Gibbous_Moon.jpg
Gibbous Moon905 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).
IC_1805_n=1_3_min_exp_E180.jpg
IC 1805905 viewsIC 1805 in Cassiopeia. The loose open cluster in the center of IC 1805 is Melotte 15. A 3-minute exposure taken with a Takahashi Epsilon 180 f2.8 with a Canon 20Da DSLR.

Antares, M4 and the Rho Oph cloud905 viewsAntares is the bright star at the lower left of the image. It is over 700 times the diameter of our Sun. Globular cluster Messier 4 is seen on the lower right. The Rho Ophiuchus cloud complex is the closest star forming region to our solar system (~430 lght years away). The cloud complex is much larger than can fit in this image. Blue reflection nebula IC 4605 seen about mid-left, and IC4603 seen middle-top are created by interstellar dust. Borg 71FL astrograph with a modified Canon XS DSLR 36min exp.
IC_1805__Heart_11_12_10_7min_TMO_Ha_mono.jpg
Heart Nebula903 viewsThe Heart Nebula, IC 1805, Sh2-190, lies some 7500 light years away from Earth and is located in the Perseus arm of the Galaxy in the constellation Cassiopeia. This is an emission nebula showing glowing gas and darker dust lanes. The open cluster of stars near the center known as Melotte 15 illuminates the nebula. This is a single 7min exposure thru an FSQ106/Ha filter from Tzec Maun Observatory in Mayhill NM.

The Veil Nebula895 viewsNGC 6992, part of the Veil Nebula in Cygnus, is the remains of a large star that exploded in a Type II supernova. The total exposure is 2 hr 25 min (29 x 300 sec lights, 30 x 300 sec darks, 64 flats; Canon 20Da, Takahashi E-180 astrograph, Paramount; Images Plus 3.82B and Adobe Photoshop CS5)

NGC7000 American Nebula895 viewsThis was taken with the stock Rebel XT lens at 55mm. It has been croped.
Veil_3-min_exp_n=3_E180_.jpg
Veil Nebula895 viewsThree 3-minute exposures stacked of the Veil Nebula in Cygnus (NGC 6960) taken with a Takahashi Epsilon 180 and a Canon 20Da DSLR
Barnard_86-NGC_6520_n_=_4_3-minute_exposures_Stacked_and_Processed.jpg
Barnard 86 and NGC 6520894 viewsBarnard 86, which is a dark nebula, and the open cluster NGC 6520 in a Milky Way star field in Sagittarius. Four 3-minute exposures stacked taken with a Takahashi FSQ 106 and a Canon 20Da DSLR (ISO 400)
The_Flaming_Star_Nebula.jpg
The Flaming Star Nebula894 viewsThe Flaming Star Nebula, IC 405, is located in the Constellation Auriga. The nebula is illuminated by the variable star AE Aurigae that is slowly passing thru the nebula but in fact did not condense from the surrounding nebula. The image acquired with a Canon 20Da DSLR (ISO 800) and a Takahashi E 180 astrograph. Total exposure time of 2.5 hrs (30 X 300 seconds lights calibrated, aligned, stacked, and stretched (DDP) in Images Plus 3.80 and further processed in Adobe Photoshop CS4).
