Venus Transit - Calcium K1351 viewsThe AAG and Oliver Lee State Park hosted a Venus transit event on 6/5/2012 to witness this "once in a lifetime event". This photo was taken using a Stellaruve SV80ED refractor, a Lunt B1200 Calcium-K module and Imaging Source DMK41AU02 camera at the event. Venus and Earth are roughly the same size- so this gives a good approximation of the size of the Sun compared to the Earth. Multiple sunspot regions also speckle the image. The AAG also had white light and hydrrogen-alpha telescopes for the crowd to witness the event.
Venus transit in white light1348 viewsThis image of the Venus transit was taken in white light (compare to image on right) through a Baader solar filter. Image taken with a TeleVue 3” f/7.4 Oracle refractor using a Baader flat field Barlow to extend the focal length (approximately f/27) and a Canon 50D DSLR @ ISO 400. Three exposures of 1/400 sec were combined and processed in Image Plus 4.50 and Adobe Photoshop CS5.
Messier 81 in Ursa Major1325 viewsM 81 is a spiral galaxy in the constellation Ursa Major was discovered by Johann Elert Bode in the 18th century. Current estimates indicate M 81 is approximately 11 million light years away. The dim companion galaxy Holmberg IX (UGC 5336) can be seen as a small blue smudge above M 81. The image was taken with a 130 mm f/8 Astro-Physics refractor with a total combined exposure of 7 hrs 40 minutes (92 x 5 min lights; 30 darks; 64 flats; SBIG ST 2000xcm @ -25 0C; AP 1200 mount)
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.
The Jellyfish 1315 viewsIC 443, aka The Jellyfish, is a large supernova remnant in the constellation Gemini. Our current understanding is that IC 443 is the remnants of a Type II supernova, the ultimate fate of a massive star, which occurred approximately 3000 to 35,000 years ago. Image is a total of 7 hr 15 min exposure (87 x 5 min lights, 30 darks, 64 flats, 64 dark flats; modified Canon 40D; Takahashi E180ED astrograph; Paramount) processed with Images Plus 4.5; PixInsight; Photoshop CS6.
Moon: Tyco/Clavius crater region1308 viewsAn image of the Tyco/Clavius region taken from Alamogordo. Tyco (53 miles in diameter, near center of image) is a relatively young crater based on samples from Apollo 17. Clavius (140 miles in diameter, lower center) is a much older crater with several smaller craters inside of it. Image taken using the C9.25 with a Imaging Source DMK41AU02 camera and Lumicon H-alpha filter. This picture is surprisingly similiar to one in the Sep/Oct 2011 SkyNews (p.36).
Galaxies in Virgo and Coma Berenices1307 viewsMany galaxies are seen in the constellations Virgo and Coma Berenices. To the bottom left is seen the spiral galaxy Messier 88, in which young stars and active star formation are present. In the lower right corner is seen the elliptical galaxy Messier 87, whose golden brown coloration is suggestive of old stars and little if any star formation. In the upper right hand quadrant is a pair of galaxies, NGC 4438 and 4435, aka the Eyes or Arp 120. Exposure is a total of 13 hr 35 min (163 X 5 min).
Messier 81304 viewsMessier 8 is an emission nebula and open cluster in the constellation Sagittarius. Our current understanding is that the clouds of gas and dust of M8 constitute a star forming region in our galaxy. The image is a total of 15 minutes exposure (3 X 300 sec) with a Takahashi E-180 f/2.8 astrograph and a Canon 20Da DSLR camera. Images calibrated, aligned, and stacked in Images Plus 3.82B and processed in Images Plus and Adobe Photoshop CS5.
The Hale 200-inch telescope1300 viewsThis summer we took a tour of Mt. Palomar Observatory. The 200-inch (5.08 m) telescope is named after astronomer George Ellery Hale. It was built by Caltech with a $6M grant from the Rockefeller Foundation, using a Pyrex blank manufactured by Corning Glass Works. The telescope (the largest in the world at that time) saw first light January 26, 1949.
M65 and M661298 viewsM65 and M66 are two galaxies in the constellation Leo. Photographed using a Takahashi FSQ 106ED and a Canon 20Da DSLR. Exposure time was 27 minutes (9 X180 sec); calibrated, aligned, stacked, and DDP stretched in Images Plus followed by Adobe Photoshop CS4.
Mercury transit 11/08/061297 views90 mm Orion refractor, Celestron NexImage w/focal reducer
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.
