Leo_Triplet_with_tidal_trail.jpg
Leo Triplet with Tidal Trail626 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.

IC_1848_(Soul_Nebula).jpg
The Soul Nebula (IC 1848)519 viewsIC 1848 the Soul Nebula, (IC 1805’s galactic neighbor) is a large emission nebula in the constellation of Cassiopeia. The image consist of 92 x 5min exposures with a Canon 60Da and Orion ED80T on a Celestron CGM mount.
Eight_hr_total_exposure.jpg
The Seven Sisters1011 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).
Messier_64_the_Black_Eye_Galaxy.jpg
The Black Eye Galaxay683 viewsMessier 64, often called The Black Eye Galaxy due to the concentration of dark dust in the galaxies center, is found in the constellation Coma Berenices. Images by the Hubble Space Telescope suggest that there are many HII and star forming regions in this dusty part of the galaxy. The interstellar medium of M64 consists of two counter-rotating disks, whereas the stars exhibit no measurable counter rotation. The image was a total of 5 h 20 min exposure taken with a TeleVue 140 f/5 refractor and SBIG ST2000xcm CCD camera on an Astro-Physics 1200 mount (32 x 10 min lights @ -20 degrees; 20 darks; 64 flats; 64 bias). Sub-exposures taken on April 29th, May 21th, and May 27th 2014. Image acquisition with MaxIm DL 5 Pro; processed with PixInsight 1.8.2.1098 and Adobe Photoshop CC.
Messier_27.jpg
Messier 27937 viewsM 27 , aka the dumbbell nebula, in the constellation Vulpecula was discovered by Charles Messier in 1764. M27 is a large cloud of expanding gas, which is the remains of a star that expelled its outer atmosphere near the end of its lifetime. M27 is a bright object that can be seen in binoculars and is a favorite telescopic object in the Spring and early Fall. Total exposure of 1 hr 40 minutes (20 x 5 min lights;30 darks; 66 flats; AP 178 f/9 refractor; Modified Canon 50D; AP 1200 mount; guided exposures)
Medusa_Nebula_in_Gemini.jpg
Abell 21621 viewsAbell 21, aka the Medusa nebula, is found in the constellation Gemini. Abell 21 is a large old planetary nebula whose emission is powered by radiation of a blue star, which can be seen in the upper 1/3 of the nebula’s image. Image taken with a Takahashi Epsilon 180 f/2.8 astrograph and a modified Canon 40D.
Jupiter_and_Moons_LinearFit_From_Steve.jpg
Jupiter526 viewsOn 1/23/2015 the shadows of Io, Callisto, and Europa were visible from Earth as they transit across Jupiter. This photo shows Io's shadow (someone correct me if I am wrong) as it transited across the gas giant. The image consist of 2,000 video frames taken with an Imaging Source camera and a Meade 8" SCT mounted on a Celestron CGEM mount. Frames were stacked with Registax6 and processed with PhotoShop CS6 and Steve's touch.

The Perseus Cluster of Galaxies83 viewsThis image of the Perseus cluster of galaxies, also known as Abell 426, is centered on NGC 1275. NGC 1275 is a giant elliptical galaxy, which is a radio source and x-ray emitter. Abell 426 is part of the Pisces-Perseus supercluster, which contains over a thousand galaxies. The image is a total of 9 hrs exposure with a Takahashi CCA-250 f/5 astrograph and a QSI683wsg camera (Astrodon Gen2 filters) on a Paramount ME taken on the nights of 7 Nov, 3, 13 Dec 2018 in Mayhill, NM (18 x 1200 sec lights; 3 x 1200 sec R, G, and B at -20 degrees; 24 darks; 128 flats; 128 bias).

Open Cluster in Cassiopeia 84 viewsThe open cluster NGC 663 is found in the constellation Cassiopeia. NGC 663 contains a significant number of Be stars (spectral class B stars showing emission lines in their spectra). The distance from us is on the order of 2,100 parsecs (6850 light years).

NGC_4631_RCOSf6_DarkMottleRepFinal_Large.jpg
The Whale Galaxy in Canes Venatici154 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 Nebula217 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
