Please do not attempt these kind of images without proper filters and never ever look directly at the sun! |

PhotographerJames CormierLocationSullivan, MaineDateMarch 22, 2012EquipmentPiggyback mounter Pentax 67 with 165 f/2.8 lens stopped down to f/4.8. A composite of two exposures, each 45 minutes in length. Images combined in Photoshop.DescriptionThe transition from the Milky Way's central hub into the galactic halo is seen in this image. Ophiuchus / Scrpius transition into Libra as we look right (west) in the image. This area is populated with many globular star clusters as you would expect in this area and in areas beyond the central portion of our galaxy. The image was taken in the early hours of a March morning, a great way to get a snek peek at the summer night sky. |

PhotographerHoward TrottierLocationCabin in the Sky Observatory, South Okanagan, British Columbia, CanadaDateFour nights between August 26 and September 1, 2011.EquipmentTelescope: PlaneWave Instruments CDK17, with a focal reducer at f/4.5. Mount: Paramount ME. Camera: SBIG STL-4020M. Image capture: TheSkyX, MaxIm DL, and FocusMax. Exposures: 300 minutes luminance (unbinned), 100 minutes in each of red, green and blue (2x2 binning). Ten-minute subframes in all channels. Image scale: 27' on a side, 0.78" unbinned pixel size. Image Processing: PixInsight with CCDInspector.DescriptionThis is a new image: although the frames were shot last summer, I could only recently complete the image processing. I was drawn to the Cave by its wide expanse of dark nebulae, the deep colors of its emission and reflection nebulae, and the vivid assortment of stars splashed across the field. I set up the shot so that a small grouping of colorful stars would spill into the corner of the frame, as if they were jewels falling out of the entrance to the cave. Over 16 hours were shot, with only the best 10 hours kept for processing. |

PhotographerMassimo ZecchinLocationCittadella (PD) - ItalyDateMarch 16, 2012 - 21.47 UTEquipmentCelestron C5 XLT on CG-4 mount TS CCD planetary camera IR-cut filter Barlow Antares 3xDescriptionThe image shows the large volcanoes of Mars that emerge from the clouds. The high contrast offered by the surrounding clouds give high contrast, allowing to capture these details with only 5" of aperture. |

PhotographerRod PommierLocationPommier Observatory, Portland, OR, USADate2012-03-07 through 2012-04-17EquipmentCelestron Compustar C14 Telescope/Mount with Tele Vue 2x Power Mate (f/22) Point Grey Research Flea3 Color Camera. Best 300 frames out of 1500 at 24 fps for left image, best 400 frames out of 3000 at 60 fps for center and right images. Seeing conditions were poor (Damian Peach scale), but clear weather in March and April are rare in Oregon, so any data are better than no data.DescriptionEarth passed between the Sun and Mars, known as opposition, on 2012-03-03 and made closest approach on 2012-03-05. Around these times, Mars ‘disk is illuminated in full phase and exhibits its greatest apparent diameter. Subsequently, Earth pulls ahead of Mars and we look back on the morning terminator of a waning gibbous Mars whose disk shrinks as it seemingly recedes in the distance. These images show that even small changes in disk size have a profound impact on the apparent sizes of surface features, like Acidalia Planitia, Margaritifer Terra, Sinus Meridiani, and Syrtis Major, making them progessively more challenging to capture. |

PhotographerCraig & Tammy TempleLocationHendersonville, TN, USADateApril 23, 2012 @ 11:56am CDSTEquipmentTelescope: Lunt Solar Systems LS60THa/B1200CPT Accessories: LS50FHa Double-stack etalon Mount: Takahashi EM-200 Temma2 Camera: Imaging Source DMK31 Exposure: 25.2ms Gain: 415 Length: 1:30 @ 30fps Acquisition: Fire Capture Processing: ImagesPlus 4.5b Post-processing: ImagesPlus 4.5b; Adobe Photoshop CS5 Capture time: April 23, 2012, 11:56am Capture conditions: 64.8°F ; transparency: Above avg 4/5; seeing: Poor 4/5DescriptionOn April 23, 2012 the Sun showed some interesting features and we were able to capture all of them in this 5-panel mosaic. While the proms along the solar limb were not large, there were many. Filaments and sunspots were also plentiful in this image. Sunspot AR1460 is at the top of this shot. Coming around to the 2 o'clock position near the limb is Sunspot AR1462. Continuing down and to the left of AR1462 is Sunspot AR1459. Moving down and slightly left is Sunspot AR1465 with a newly emerging Sunspot region directly to its left. |
