White Light Sun713 viewsSunspot AR2403 is almost 200,000 km long and is easily visible in this image taken from Maryland on 8/25/2015 using an Orion ED80T Triplet refractor and a color Atik 414ex camera. The telescope was equipped with a white light filter and the exposure was set to 0.001 sec. Light was further reduced by using a Moon filter in fromt of the camera. Great shot Chuck!

Annular Eclipse of the Sun1380 viewsAnnular eclipse of the sun on May 20, 2012 between 7:33:39 – 7:38:05 pm MST (DST in effect) was photographed near Albuquerque, New Mexico in the Cibola National Forest by Sandia peak at an elevation of 6559 feet. The image was taken through Baader solar film with a Nikon D100 DSLR with a Nikon ED 70-300 lens @ 300 mm ( 1/60th second exposure at ISO 200).

Mars and Saturn 2012998 viewsHere is a collage of Mars and Saturn from 2/19/2012. Mars nearest approach to Earth occurs in early March 2012, however it will be almost 60 million miles from Earth (making its disk appear small compared to recent years). Saturn will reach opposition in mid-April 2012, so the disk will be growing larger with each day. Come to our Spring events to see Saturn for yourself !

M46793 viewsMessier 46 (M46, NGC 2437) This open cluster is very rich, with 150 stars of mag 10-13 and probably a total population of over 500. The brightest of these stars are of spectral type A0, and each about 100 times more luminous than the Sun (the brightest is of apparent magnitude 8.7). This indicates an age of about 300 million years. As a special and famous feature which is also obvious in my photograph, a planetary nebula (NGC 2438, also FC 87) appears within the apparent borders of M46. This object appears to lie near the northern fringes of the cluster. However, this nebula is not a true member but is superimposed, or perhaps a passing "guest". The distance of the cluster is 4,600 light years and only about 2,900 light years for the nebula

Messier_81_in_Ursa_Major.jpg
Messier 81 in Ursa Major1413 viewsM 81 is a spiral galaxy in the constellation Ursa Major was discovered by Johann Elert Bode in the 18th century. Current estimates indicate M 81 is approximately 11 million light years away. The dim companion galaxy Holmberg IX (UGC 5336) can be seen as a small blue smudge above M 81.

California_Nebula__NGC_1499.jpg
The California Nebula824 viewsNGC 1499, aka the California Nebula, is a large emission nebula in Perseus. It is about 2.5 degrees in length and has a very low surface brightness, which makes it somewhat of a challenge to observe visually. The image was taken with a Canon 60Da DSLR and a Takahashi FSQ106ED telescope with focal reducer (f/3.6 FL = 385 mm) on an Astro-Physics 1200 mount. Total combined exposure was 5 hrs (20 x 15 min guided and dithered lights; 12 darks; 128 bias; 64 flats) taken over three nights (Oct 23rd , 27th , 28th 2014). Image acquisition with MaxIm DL6.07 and calibration, registration, and integration with PixInsight; processing with PixInsight 1.8.3.1123 Ripley (x64) and Adobe Photoshop CC.

The Perseus Cluster of Galaxies474 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).

NGC4565Large.jpg
An Edge-On Spiral Galaxy in Coma Berenices496 viewsNGC 4565, sometimes referred to as the Needle Galaxy, is an edge-on galaxy in the constellation Coma Berenices. One can see the galaxy's yellowish central core, which is divided by obscuring dust lanes running the length of the equatorial plane.

NGC_4631_RCOSf6_DarkMottleRepFinal_Large.jpg
The Whale Galaxy in Canes Venatici525 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 Nebula703 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
