  1. From the album: Deep Sky Imaging

    Close up image of Gum 53 or NGC 6188 (AKA Fighting Dragons) imaged in narrowband and SHO channels combined into "Hubble palette". NGC6188 is an emission nebula located 4,000 light years away in the constellation Ara. This image was exposed with a cooled and full spectrum modded DSLR, though an 8" SCT at 2032mm focal length. The total exposure through all narrowband filters is 50 hours and 46 minutes.

  3. The Fighting Dragons of Ara ( NGC 6188 ) ( please click / tap on image to see larger ) The Fighting Dragons of Ara ( NGC 6188 ) Bright Nebula NGC 6188 and open cluster NGC 6193 are embedded 4,300 light years away in the Sagittarius arm of our Milky Way galaxy and can be seen with the naked eye south of Scorpius in the constellation of Ara. With powerful stellar winds and energetic ultra-violet radiation, massive stars sculpt the interstellar gas and dust of the nebula into wonderful shapes and cause the interstellar gas to brightly fluoresce. Closer to the hot young stars of the cluster, bright blue “sunlight” reflects off the clouds of gas and dust to produce the blue reflection nebulae seenin the image. Magnitude +5.19, RA 16h 41m 42s, Dec -48deg 48' 46". Approx. 3800 light years away. Image details: This is an HDR image constructed from exposures ranging from 2 seconds to 240 seconds in length. The aim was to capture the faint stars and details in the nebula whilst at the same time maintaining colour in the bright stars without clipping the highlights. Plate Solution: Resolution ........ 1.336 arcsec/px Rotation .......... 90.002 deg ( North is to the right ) Focal ............. 1475.57 mm Pixel size ........ 9.56 um Field of view ..... 58' 28.5" x 39' 0.8" Image center ...... RA: 16 40 09.903 Dec: -48 41 27.00 Telescope: Orion Optics CT12 Newtonian ( mirror 300mm, fl 1200mm, f4 ). Corrector: ASA 2" Coma Corrector Quattro 1.175x. Effective Focal Length / Aperture : 1410mm f4.7. Mount: Skywatcher AZ Eq6 GT. Guiding: TSOAG9 Off-Axis-Guider, Starlight Xpress Lodestar X2, PHD2 . Camera: Nikon D5300 (unmodified) (sensor 23.5 x 15.6mm, 6016x4016 3.9um pixels). Location: Blue Mountains, Australia Moderate light pollution ( pale green zone on darksitefinder.com map ). Capture ( 24 June 2017 ). 8 sets of sub-images with exposure duration for each set doubling ( 2s to 240s ) all at ISO800. 34 x 240s + 10 each @ 2s to 120s. Processing ( Pixinsight - 19 Aug 2017, 13 Jan 2018 ). Calibration: master bias, master flat and no darks. Integration in 8 sets. HDR combination. ......... This is a reprocessed version using the data I captured earlier in the year...
  4. This object in my color palette remarkably resembles the legendary work of Michelangelo - The Creation of Adam. In honor of this cosmic similarity, I named it similarly - The Creation of the Cosmos The NGC 6188 is fantastic - probably one of my favorites. I hope you will like my interpretation. I am open to criticism. Equipment: ASI1600MM-C with Baader Narrowband FIlters (8h total exp), WO APO71Q f4.9 telescope, iOptron CEM25EC paralactic mount. Location – village without civilization somewhere in the middle of South Africa. Thanks for your feedback guys. Click for bigger version (hi quality - 50%):
