Sculptor Galaxy741 viewsThe Great Sculptor Galaxy (NGC 253), aka the Silver Coin, in the constellation Sculptor was discovered in 1783 by Caroline Herschel. The galaxy is at a distance of 9.8 million light years away from us. Research on NGC 253 indicates that it is a starburst galaxy, which means that it has recently hosted massive and rapid burts of star formation. The image is a total of 1 hr 50 min (22 X 300 seconds) exposure with a Takahashi E-180 astrograph and Canon 20Da DSLR camera.
Gibbous Moon740 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).
Polaris Star Trails - Second Try734 viewsThis is a 30 min. shot of polaris. You can see the lights from the steet I shot this over starting to brighten up the bottom of the image.
NGC 6559, IC 1274/75, and IC 4685 region in Ha730 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).
The Moon729 viewsThe Moon, our nearest neighbor, provides a wealth of detail even in small telescopes. Indeed, as Garrett Serviss wrote regarding the distance to the moon in his book "Other Worlds" in 1901: "In consequence, of course, of its nearness, the moon is the only member of the planetary (solar) system whose principal features are visible to the naked eye." Image taken with a Astro-Physics 130 mm f/8 refractor and a Canon 20Da DSLR (11 X 1/250 second exposures at ISO 200; aligned and combined in Images Plus).
The Flaming Star Nebula729 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).
What a diiference a filter makes!727 viewsHere is the Sun taken on 10/3/11 at 11:15 AM first in White light (left) and Calcium K (right) using a Stellarvue 80ED. The white light image shows a few sunspot groups while the CaK image shows much more detail and areas of increased magnetic activity. AR1302 is on the far right, nearly rotating out of view. The white light image was taken using an Orion glass filter and single snapshot from a Canon T2i. The CaK image was taken with an Imaging Source camera and Lunt B1200 CaK filter.
M1725 viewsFirst light Shot from me ST-6 and new Mount. This is a single 4 minute shot at prime focus through my C8. Needs more time and better seeing.
IC 1805723 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.
The Veil Nebula722 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)
Barnard 86 and NGC 6520719 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)
Jumpin' Jupiter!718 viewsJupiter is nearing its 2009 opposition - so I thought I'd go out and practice. Shot with the Celestron C9.25/CGE at f/25 (5875mm) with the NexImage/Televue Powermate (2.5x) from the backyard. I shot at 20 fps to get the most amount of images (1800). Stacked with Registax 2.0, Processed with Photoshop 7.0.1.
