Leo_Triplet_with_tidal_trail.jpg
Leo Triplet with Tidal Trail929 viewsMessier 65, Messier 66, and NGC 3628 are commonly known as the Leo Triplet. M 65 is a spiral galaxy whose center is comprised of older yellowish stars (bottom left center of image). M 66 (top center) and NGC 3628 (top right center of image; aka the hamburger galaxy) are suggested to have had a past encounter that resulted in a faint tidal trail seen coming off the top of NGC 3628. The image was captured with a modified Canon 40D (ISO 800) and a Takahashi E180 f/2.8 astrograph on a Paramount. Total exposure time was 8 hours (48 X 10 min guided sub-exposures; 13 darks; 64 flats; 64 flat darks). Calibrated and stacked with Images Plus 5.0; processed with PixInsight 1.8 followed by final Levels and Curves adjustment in Adobe Photoshop CS6.
CrescentNebula.jpg
The Crescent Nebula in Cygnus622 viewsThe Crescent Nebula (NGC 6888) is an emission nebula found in the constellation Cygnus. A leading hypothesis suggests that the strong stellar winds from the central Wolf-Rayet star collides with the stars outer atmospheric envelope ejected in a previous evolutionary phase, which energizes the nebula and leads to the observed structure. This H alpha image is a total of 5 hours of exposure taken with a Takahashi CCA-250 f/5 astrograph and QSI683wsg camera (Astrodon 5 nm Ha filter) on a Paramount ME; August 11th , 13th 2015 in Mayhill, NM (15 x 1200 sec lights @ -20o C; 21 darks; 126 bias; 128 flats) Image acquisition MaxIm DL 6.08; Calibration, alignment, integration, and processing in PixInsight 1.8.4.1107 Ripley (x64).

What a diiference a filter makes!1231 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.
IC5070.jpg
IC5070 (Pelican Nebula)772 viewsIC5070 (Pelican Nebula) located in the constellation of Cygnus is part of a large H-II cloud. The hydrogen gas is excited by the energy originating from nearby stars, and then emits its own light in the red wavelength of hydrogen. The image consist of 4 hours of exposures taken with a Canon 60Da camera, ES 127mm refractor with .8 reducer, mounted on a Celestron CGEM mount. The image was stacked with Nebulosity 4 and processed with Pixinsight 1.8.

Eight_hr_total_exposure.jpg
The Seven Sisters1357 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).

The open cluster contains 186 stars brighter than 13th magnitude and many more fainter stars. The cluster lies in our Milky Way galaxy at a distance of approximately 4480 light years from us. Image is a total of 1 hr 45 minutes exposure ( 21 x 5 min lights @ -25o C; 30 darks; 64 flats; Astro-Physics 130 mm f/8 refractor & 1200 mount; SBIG ST2000XCM CCD camera).

NGC_4631_RCOSf6_DarkMottleRepFinal_Large.jpg
The Whale Galaxy in Canes Venatici505 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).

IC_443_Large.jpg
Turbulent nature of the Jellyfish Nebula681 viewsFound in the constellation Gemini, the Jellyfish Nebula, also designated IC 443, is a large supernova remnant. The emission of the nebula is due to the excitation of hydrogen atoms as the rapidly expanding shell collides with the surrounding molecular gas. This hydrogen-alpha image shows the turbulent nature of the nebula as the resultant shock wave expands. Image taken with a Takahashi CCA-250 f/5 astrograph and QSI683wsg CCD camera (Astrodon 5nm H-alpha filter) on a Paramount ME in Mayhill, NM on the nights of the 23rd, 24th January 2018. Total of 7 hr exposure (21 x 1200 sec lights @ -20 degrees C; 24 darks; 128 bias; 128 flats). Processed in PixInsight 1.8.5.1353 Ripley (x 64).Jun 30, 2018
