NGC_6820_and_6823.jpg
NGC 6820 and 68231122 viewsNGC 6823 is an open cluster in Vulpecula, whose center contains 9th magnitude stars along with fainter members that is immersed in the faint emission nebula NGC 6820. Photographed with a Takahashi Epsilon 180 f/2.8 and Canon 20Da DSLR on a Paramount (Ten 5-minute exposures at ISO 800; calibrated, aligned, combined and processed in Images Plus V 3.80 (DDP stretch) followed by Adobe Photoshop CS4).
M33.jpg
The Pinwheel Galaxy1364 viewsMessier 33, aka the Pinwheel Galaxy or Triangulum galaxy, is found in the constellation Triangulum. At magnitude 5.7 it can be seen with the naked eye under dark skies. Its low surface brightness, however, often makes it a challenge even with large amateur telescopes in suburban locations. Image taken with a Takahashi E-180 astrograph and Canon 20Da camera; total exposure 1 hr 40 minutes (20 x 300 sec lights, 30 x 300 sec darks, 64 flats); processed with Images Plus 3.82b and Photoshop CS5.
NGC_1499_California_Nebula.jpg
NGC 14991211 viewsNGC 1499, aka the California Nebula, is a diffuse nebula found in the constellation Perseus. The nebula, which is composed primarily of hydrogen gas, was discovered by E. E. Barnard in 1884 using a 6-inch refractor. The image is a total exposure of 3 hours 5 min (37 x 300 sec lights) using a Takahashi E-180 astrograph and a Canon 20Da DSLR at ISO 800 (30 darks, 67 flats). Image processed using Images Plus 3.82b and Adobe Photoshop CS5.
Messier_8.jpg
Messier 81404 viewsMessier 8 is an emission nebula and open cluster in the constellation Sagittarius. Our current understanding is that the clouds of gas and dust of M8 constitute a star forming region in our galaxy. The image is a total of 15 minutes exposure (3 X 300 sec) with a Takahashi E-180 f/2.8 astrograph and a Canon 20Da DSLR camera. Images calibrated, aligned, and stacked in Images Plus 3.82B and processed in Images Plus and Adobe Photoshop CS5.

The Veil Nebula1309 viewsNGC 6992, part of the Veil Nebula in Cygnus, is the remains of a large star that exploded in a Type II supernova. The total exposure is 2 hr 25 min (29 x 300 sec lights, 30 x 300 sec darks, 64 flats; Canon 20Da, Takahashi E-180 astrograph, Paramount; Images Plus 3.82B and Adobe Photoshop CS5)
IC_417_and_NGC_1931.jpg
The Spider and the Fly1531 viewsIC 417, aka the spider, located in the constellation Auriga is the bright emission nebula in the center of the image. The smaller emission and reflection nebula NGC 1931, aka the fly, is located to the right. In the upper left-hand corner is the emission nebula IC 410. Exposure was a total of 3 hr 10 min (38 X 5 min) with a Takahashi E-180 and modified Canon 40D @ ISO 800 (30 darks, 60 flats). Image aquisition with Images Plus 4.0; Calibration, alignment, and stacking in Images Plus 3.82b.
IC_2177_and_the__van_den_Bergh_93_reflection_nebulosity.jpg
IC 2177 emission and the van den Bergh 93 reflection nebulosity1736 viewsIC 2177, in the constellation Monoceros, is the large red emission nebula. IC 2177 is often called the Seagull Nebula, embedded in the head of the seagull is van den Bergh 93 (slightly left of center in the image) that actually refers only to the blue reflection nebulosity. Image is a total exposure of 2 hrs 30 mins (30 darks; 60 flats; modified Canon 40D; Takahashi E-180; image aquisition Images Plus 4.0; Calibration, alignment, and stacking in Images Plus 3.82b; Adobe Photoshop CS5)
Messier_82_Total_exposure_685_minutes.jpg
Messier 82, a starburst galaxy1221 viewsMessier 82, a galaxy in the constellation Ursa Major, was discovered by Johann Elert Bode in 1780. Today we know M82 is a starburst galaxy where a large number of new stars are being born. Large amounts of in-falling gas are excited by the newly formed stars and are responsible for the red Ha emissions Total exposure was 11.4 hours (137 x 5 min lights) taken with a 130 mm f/8 Astro-Physics refractor and SBIG ST 2000xcm CCD camera on an Astro-Physics 1200 mount. Processed in Images Plus 4.5 and Adobe Photoshop CS5
Messier_82_in_the_constellation_Ursa_Major.jpg
Messier 82 in Ursa Major917 viewsMessier 82 in the constellation Ursa Major, which contains the familiar star group or asterism “the Big Dipper”. Messier 82 is a classic example of a starburst galaxy, in which is undergoing a high rate of star formation. This image was taken with a 130 mm f/8 Astro-Physics refractor and a SBIG ST2000xcm CCD camera on an AP1200 mount. Image was a total of 11 hrs 25 min exposure (137 x 5 min lights; 30 darks; 64 flats); Calibrated in Images Plus 5.0 and processed with PixInsight 1.8 and Photoshop CS6.
MultiscaleHaLumFinal.jpg
Messier 82713 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. Total of 9 hr 20 min exposure with a Takahashi CCA-250 f/5 astrograph; Nights of 15, 28 March 2015, 12, 13 Jan 2016, 8, 9 Feb 2016; 2015 Paramount ME, QSI 683wsg, 5 nm Astrodon Ha filter (Lum 11 x 20 min @ - 20 degrees C; Ha 17 x 20 min @ - 20 degrees C), calibrated, registered, integrated, and processed in PixInsight 1.8.4.1195.
Messier82_sRGB.jpg
The starburst galaxy Messier 82703 viewsThis HaLRGB image portrays the turbulent 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 supernovae resulting from their death) being born at a high rate within the galaxy. Total of 18 hrs exposure with a Takahashi CCA-250 f/5 astrograph; Nights of 15, 24, 28 March 2015; 12, 13 Jan 2016; 8, 9 Feb 2016: 2015 Paramount ME, QSI683wsg, Astrodon Gen2 filters (Ha 5 nm); (Lum 16 x 20 min; Ha 17 x 20 min; R 7 x 20 min; G 7 x 20 min; B 7 x 29 min all @ - 20 degrees C), calibrated, registered, integrated, and processed in PixInsight 1.8.4.1195 (x 64).
