Ha_image_of_Messier_8_in_false_color.jpg
Hydrogen alpha image of Messier 81592 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 2177 emission and the van den Bergh 93 reflection nebulosity1814 viewsIC 2177, in the constellation Monoceros, is the large red emission nebula. IC 2177 is often called the Seagull Nebula, embedded in the head of the seagull is van den Bergh 93 (slightly left of center in the image) that actually refers only to the blue reflection nebulosity. Image is a total exposure of 2 hrs 30 mins (30 darks; 60 flats; modified Canon 40D; Takahashi E-180; image aquisition Images Plus 4.0; Calibration, alignment, and stacking in Images Plus 3.82b; Adobe Photoshop CS5)
Seagull.jpg
IC2177 and NGC2327898 viewsIC2177 is a large diffuse nebula near the constellations of Monoceros and Canis Major. The sweeping arc forms the seagull’s wings while the head consist of NGC 2327 (also call the Parrot nebula). This image consist of 80 x 300sec images taken with a Canon 60Da, Orion ED80T refractor, and a Celestron CGEM Mount. Stacked in Nebulosity and processed with PhotoShop CS6
Eight_hr_total_exposure.jpg
The Seven Sisters1449 viewsThe star cluster Messier 45 in the constellation Taurus is popularly referred to as the Pleiades or Seven Sisters. The blue color of the reflection nebulosity is due to the blue light of the brightest stars being scattered by the surrounding dust. The pink tones in the right hand portion of image are due to weak emission of a gaseous component. Total combined exposure is eight hours with a modified Canon 40D DSLR at ISO 800 and a Takahashi Epsilon 180 f/2.8 astrograph (96 x 5 min lights; 64 flats; 30 darks; Paramount; Images Plus and Adobe PhotoShop CS5).

IC 410 and the Tadpoles in Ha725 viewsThe emission nebula IC 410 and the embedded open star cluster NGC 1893 are found in the constellation Auriga. The emission of IC 410, which is about 12,000 light-years away, is powered by the young hot stars in NGC 1893. The gas streamers just to the right and above center, often called the “Tadpoles”, are moving away from the center of the nebula. The image is a Ha image, which shows the extent of the hydrogen emission in the region. The image was taken with a Takahashi CCA-250 astrograph and the QSI683wsg camera (SBIG ST-i guider) on a Paramount ME. The image is a total of 8 hours exposure (24 x 20 min lights @ -20 degrees C, dithered; 21 darks; 126 bias; 128 flats), acquired with MaxIm DL 6.07, and processed with PixInsight 1.8.3.1123 Ripley (x64). Ha filter was an 5nm bandwidth 31 mm Astrodon Gen 2 filter.

Mare Nectaris/Theophilus crater1345 viewsThe Sea of Nectar (Mare Nectaris) is a small lunar mare located on the eastern edge of the Moon. Theophilus is the prominent lunar impact crater that lies slightly off center of the image to the left. Theophilus is over 60 miles in diameter and is 14,000 feet deep. The small crater in Nectaris near the top of the image is Rosse and is only 7 miles across. Image taken with a 6" SCT at f20 using a DMK 41AU02 camera through a Lumicom 656 nm filter.

NGC_4631_RCOSf6_DarkMottleRepFinal_Large.jpg
The Whale Galaxy in Canes Venatici614 viewsNGC 4631 is found in the constellation Canes Venatici. The wedge-shape of this galaxy gives rise to its nickname, the Whale Galaxy. The starburst regions of this galaxy can be seen in the photo, which are due to intensive star formation. Tidal interactions of NGC 4627, which is seen just above NGC 4631, has been suggested as one of the reasons for the active core of NGC 4631 (as well as tidal interactions with other nearby galaxies). The small edge-on galaxy at the top of the image is PGC 3794315 (NASA Extragalactic Database). Total of 5 hr 40 min exposure taken with an SBIG STF8300c CCD camera and a 12.5 inch RCOS f/9 astrograph operating at f/6 (Astro-Physics CCDT067 reducer) mounted on a Paramount ME on the nights of 8, 15, 16 May 2018 in Mayhill, New Mexico (17 x 1200 sec Lights @ -15 degrees C; 15 darks; 128 bias; 128 flats).
