Rho_Ophiuchus_region_2012_05_16_71FL_XS_36min_iso800.jpg
Antares, M4 and the Rho Oph cloud687 viewsAntares is the bright star at the lower left of the image. It is over 700 times the diameter of our Sun. Globular cluster Messier 4 is seen on the lower right. The Rho Ophiuchus cloud complex is the closest star forming region to our solar system (~430 lght years away). The cloud complex is much larger than can fit in this image. Blue reflection nebula IC 4605 seen about mid-left, and IC4603 seen middle-top are created by interstellar dust. Borg 71FL astrograph with a modified Canon XS DSLR 36min exp.

Messier_45_with_Epsilon_130.jpg
The Pleiades Open Star Cluster425 viewsMessier 45, commonly known as the Pleiades or Seven Sisters, is found in the constellation Taurus. The structure in the nebulous regions is created by interstellar magnetic fields. The image was captured using a Takahashi E-130D f/3.3 astrograph and a SBIG STF-8300c camera on a Paramount. Total integration time was 4 hr 20 min (26 x 10 min lights @ -20 degrees C; 20 darks; 64 flats, 64 bias). Images were graded in Images Plus 5.0; Subs calibrated, registered, integrated, and processed in PixInsight 1.8 Ripley with final levels/curves adjustment in Adobe Photoshop CC.

The Celestial Bubble in Cygnus236 viewsThe Soap Bubble Nebula, or PN G755.5+1.7 is likely a faint planetary nebula found in the constellation Cygnus. The faint nebula was discovered relatively recently in 2008 on photographs of the Cygnus region. A cropped hydrogen-alpha image attached. Image was a total of 5 hr 40 min taken with a Takahashi CCA-250 f/5 astrograph with a QSI683wsg camera (Astrodon Gen2 Ha filter 5 nm) on a Paramount on the nights of 2, 4 October 2016 in Mayhill, NM (17 x 1200 sec H-alpha lights @ -20 degrees; 23 darks; 128 flats; 126 bias; processed in PixInsight 1.8.4.1195).

M8_and_M20.jpg
Lagoon Nebula (M8) and Trifid Nebula (M20)145 viewsThe Lagoon Nebula (M8) on the left and Trifid Nebula (M20) on the bottom right are located in the constellation of Sagittarius. M8 is an emission nebula about three times the size of the full moon. The nebula’s brightest region is illuminated by two supper giant stars while the rest of the nebula is illuminated by the open star cluster NGC 6530. M8’s smaller neighbor, M20, is a combination of emission nebula (red) and reflection nebula (blue). The image consist of 4 hours of exposure taken with a Canon 60Da camera and Orion ED80T telescope mounted on a Celestron CGEM mount. Exposures were stacked with Nebulosity 4, processed with PixInsight 1.8, and minor cosmetic touches with Photoshop CS6.

M45final2015.jpg
M 45 and associated Nebulosity228 viewsMessier 45, commonly known as the Pleiades, is an open cluster found in the constellation Taurus. Messier 45 is surrounded by a dusty reflection nebula, which accounts for its blue coloration, along with some pinkish-red coloration due to an ionized gas component. The small 17.3 magnitude galaxy PGC 13696 can be seen to the right of the star Electra (17 Tau), which is the bright star to the right of center.
The data was previously obtained on the nights of November 1st, 2nd, and 3rd, 2013 with a OSC SBIG STF-8300c camera and Takahashi E-130D f/3.3 Astrograph on a Paramount (Mayhill, NM). Total integration time was 4 hr 20 min (26 x 10 min lights @ -20 degrees C; 20 darks; 64 flats, 64 bias). Calibrated, registered, integrated, and processed in PixInsight 1.8.3.1123.
Some comments on processing: The calibrated, registered, and integrated OSC image was duplicated and the R, G, and B channels extracted. The R, G, and B channels were combined with the Integration Tool to prepare a synthetic luminance (SynL). Dynamic Background Extraction ( DBE) and Deconvolution applied to the SynL image. DBE, Background Neutralization, and Color Calibration was applied to the original RGB image. Both the RGB and SynL images were stretched (Masked Stretch tool). The luminance (“lightness” using L*a*b*) was extracted from the RGB image and the Linear Fit tool was used to match the stretch of the luminance to the SynL channel (SynL as reference). The fitted luminance was added back to the RGB image using the Channel Combination tool in L*a*b* mode. The SynLRGB image was made using LRGB Combine tool. Further processing included noise reduction, multiscale processing to bring out faint structure, color saturation, sharpening, and contrast enhancement.

The_Emission_Reflection_Nebula_NGC_1333_in_Perseus.jpg
The emission-reflection nebula NGC 1333 in Perseus233 viewsNGC 1333 is a blue reflection nebula with associated star forming regions in the molecular cloud/dust region in the constellation Perseus. The star forming regions contain many new stars less than 1 million years old. Red regions of ionized gas energized by these young stars can be seen in the image. Also seen to the left of the blue reflection nebula is the dark nebula Barnard 205. Image is a total of 5 hrs 45 min combined exposure taken on the nights of 23, 27, and 28 October 2014 taken with a SBIG ST2000xcm camera and TeleVue 140 f/5 refractor on an Astro-Physics 1200 mount (23 x 15 min lights @ -20 degrees, dithered; 32 darks; 128 bias; 128 flats). Software: Sky X; Image acquisition with MaxIm DL 6.05; Calibration, registration, and integration in PixInsight; Processing with PixInsight 1.8.3.1123 Ripley (x64) and Adobe Photoshop CC.
