The Hale 200-inch telescope1533 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.

Narrowband Horsehead region1892 viewsThis is a narrowband image of the Horsehead nebula (B33) region in Orion taken with the Tzec Maun telescope in Mayhill. The "Horsehead" is actually a cold, thick, dark gas that is blocking the light from the bright (emission) nebula behind it. Hydrogen is indicated with red, sulfur is in green (yellow is a combination of hydrogen and sulfur) and Blue is Oxygen. The dats was collected back in January 2011 (3.5 hours worth) and processed by Steve. Thanks Steve !

More Calcium-K1075 viewsThis image from Jan 17,2012 shows active regions 1401/1402 in Calcium K (393.4 nanometers) as they rotated into view. This region recently threw off a coronal mass ejection (CME) that impacted Earth's magnetic field on Jan 22, 2012 creating auroras at the northern latitudes. To learn more about space weather and its impact to us on Earth, go to our AAG Classroom page and watch the video on space weather. Imaged at f14 using a Stellarvue SV80ED, Lunt B1200 CaK filter and Imaging Source camera.
Jupiter_2012_01_03_C6_f25_LR_deconvolution-3it.jpg
Majestic Jupiter1077 viewsJupiter is seen high overhead in Jan 2012 after sunset. This image of Jupiter was taken on Jan 3, 2012 from Alamogordo using a Celestron C6 SCT at f25 (3750mm) and NexImage webcam. Jupiter's moon Io is seen on the left, Europa is on the right. Ganymede is transiting across the face of Jupiter to the lower left. Jupiter has equatorial bands whose colors are generated by churning in its atmosphere. Tinkered with Lucy-Richardson deconvolution to bring out extra detail.

Messier 82828 viewsThis combined Ha and Luminance image shows the starburst galaxy Messier 82 in Ursa Major with its filamentary outflows of ionized hydrogen. This emission is suggested to be due to stellar winds caused by massive energetic young stars (as well as supernova resulting from their death) being born at a high rate within the galaxy.

Herschel in 1784, NGC 2903 is approximately 20 to 30 million light years away. Image was taken with a 12.5” f/9 RCOS telescope and a SBIG STF8300c camera with an OAG (ST-i) on a Paramount ME.

The edge-on galaxy NGC 891 in Andromeda 810 viewsThe edge-on galaxy NGC 891 is found in the constellation Andromeda. NGC 891 is approximately 30 million light-years away and is similar in size to our own Milky Way galaxy. A prominent dust lane is seen in the plane of the galaxy with tendrils of dust seen above and below that plain. These dust tendrils may be due in part to supernova explosions. The image is a total of 11 hours of exposure through a 12.5 inch f/9 RCOS astrograph with a SBIG STF8300c CCD camera on a Paramount ME taken in Mayhill, NM on the nights of 13, 14 Oct 2016; 16 Nov 2017; 13, 15 Dec 2017, and 13, 19 Jan 2018 (33 X 1200 sec lights @ -15 degrees C; 18 darks, 128 bias; 128 flats).

IC_443_Large.jpg
Turbulent nature of the Jellyfish Nebula889 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).
