Andromeda.jpg
Andromeda Galaxy567 viewsThe Andromeda Galaxy (M31) located around 2.5 million light years from Earth is estimated to be the largest galaxy of our local group. This photo also shows Andromeda’s satellite galaxies M32 (NGC 221), left center, and M110 (NGC 205) to the lower right.

Saturn_2013_05_25_C9_25_21AU618_f25.jpg
The Ringed Planet755 viewsSaturn is the 6th planet from the Sun at a distance of about 900 million miles. The rings are composed primarily of water ice with particles the size of snowflakes up to house-sized boulders. The rings extend almost 50,000 miles above the planet and average about 60 feet thick (paper thin indeed). To learn more about Saturn, go to our "PLANETS" page. Celestron C9.25 at f25, Imaging Source 21AU618 color camera.

Each cluster contains about 300 stars, many of which are blue-white supergiants. Image is a total of 5 hours combined exposure (20 x 900 sec lights, -20 degrees C; 35 darks; 126 flats; 128 bias) taken with an SBIG STF8300c camera; Takahashi Epsilon 180 f/2.8 astrograph; Astro-Physics 1200 mount; Image acquisition with MaxIm DL 6; processed with PixInsight 1.8.3.1123.

Hubble's variable nebula in Monoceros447 viewsHubble's Variable Nebula (NGC 2261) is a small 2 x 4 arcminute nebula found in the constellation Monoceros. One suggestion proposed for the observed variability is due to dust clouds near R Monocerotis periodically changing the nebula's illumination. The image was a total of 6 hr 20 min exposure with a 12.5” f/9 RCOS telescope and SBIG STF8300c camera (OAG with ST-i) on a Paramount ME (19 x 1200 sec lights @-15o C; 30 darks; 128 bias; 128 flats); Software: Sky X, MaxIm DL6, PixInsight 1.8.4.1195.

What a diiference a filter makes!885 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.

NGC663FinalsRGB_Large.jpg
Open Cluster in Cassiopeia 15 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). The image is a total of 5 hrs 20 min exposure taken with a 12.5” RCOS f/9 @ f/6 (Astro-Physics CCDT67) and SBIG STF8300m camera on a Paramount ME in Mayhill, NM on the nights of 28 Nov and 3 Dec, 2018 (6 x 1200 sec R; 5 x 1200 sec G & B; 24 darks; 128 bias; 128 flats). Processed in PixInsight 1.8.5.1353 Ripley (x64).Jan 18, 2019

A Large Emission Nebula in Cassiopeia45 viewsNGC 281 is a H II emission nebula in Cassiopeia containing the open cluster IC 1590, which powers the ionization of the hydrogen gas. Large dust filaments as well as Bok globules, which may be the site of future star formation, can be seen. The image is a total of 5 hrs 20 min exposure in H alpha light. Image taken with a Takahashi CCA250 astrograph and QSI683wsg camera on a Paramount ME on the nights of 13, 15 Dec, 16 Nov 2018 in Mayhill, NM (16 x 1200 sec lights @ -20 degrees C.

NGC4565Large.jpg
An Edge-On Spiral Galaxy in Coma Berenices52 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. Total exposure was 10 hrs 20 min taken with a Takahashi CCA-250 f/5 astrograph and QSI683wsg CCD camera (Astrodon Gen2 filters) on a Paramount ME in Mayhill, NM on the nights of 8, 15, 16 May; 17, 18 June 2018 ( 21 x 1200 sec lights; 4 x 1200 sec R; 3 x 1200 sec G; 3 x 1200 sec B all @ -20 degrees C; 24 darks; 128 bias; 128 flats for each channel).

NGC_4631_RCOSf6_DarkMottleRepFinal_Large.jpg
The Whale Galaxy in Canes Venatici87 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). Processed with PixInsight 1.8.5.1353 Ripley (x64).Jul 13, 2018
IC_443_Large.jpg
Turbulent nature of the Jellyfish Nebula137 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

An Open Cluster and Nebula in the constellation Auriga357 viewsNGC 1931 is a relatively young open cluster surrounded by emission and reflection nebulosity (Sharpless 2-237) in the constellation Auriga. Faint red hydrogen emission can be see in the region surrounding the compact cluster/nebulosity. Sharpless 2-237 shows both red hydrogen emission and blue reflection nebulosity. Image was a total of 15 hours of exposure through a Takahashi CCA250 f/5 astrograph with a QSI683wsg camera @ -20 degrees C. (Astrodon Gen 2 filters) on a Paramount ME on the nights of 23, 30 Nov and 5 Dec 2016 and 13, 18, 19 Jan 2018 in Mayhill, NM (Lum 30 x 1200 sec; Red 5 x 1200 sec; Green 5 x 1200 sec; Blue 5 x 1200 sec; with corresponding Flats, Darks, and Bias). Processed in PixInsight 1.8.5.1353 Ripley (x64). Color calibration and RGB image stretch with PixInsight's Photometric Color Calibration and Arcsinh Stretch, respectively.Mar 30, 2018
