IC5146 – Cocoon Nebula Small silky ball laid at the end of a dark footpath, between Cassiopea and Cygnus, the small Cocoon Nebula glows with soft red and mauve colors in a sanctuary of stars. This lovely object, catalogued IC5146, Sharpless 2-125 or Caldwell 19, is a hot emission hydrogen cloud where young stars are… Continue reading IC5146 – Cocoon Nebula
IC434 – Horse Head area In the same constellation as the Great Orion Nebula, up north, there is a immense hydrogen cloud field offering a great background to two fantastic objects… The most famous one is the Horse Nebula, named after its shape as seen from our direction and catalogued as Barnard 33. It is… Continue reading IC434 – Horse Head area
M42 – Orion Nebula Given the amount of pictures on social networks, capturing and processing this famous nebula has become quite demanding. This target is visible during the cold season in the Northern hemisphere, from November to end of February in my backyard, counting roofs and vegetation. What makes this object difficult is the luminosity… Continue reading M42 – Orion Nebula
IC1805 – Heart Nebula The Heart Nebula is located between Cassiopea and Perseus. It is a large area that required a 2-pane mosaic to cover. There is a star cluster at the center of the nebula, catalogued as Melotte 15, and a huge amount of dusty filaments. This was my first pleasantly successful mosaic with… Continue reading IC1805 – Heart Nebula
M51 – Whirlpool Galaxy What we call the Whirlpool Galaxy is actually a pair of galaxies interacting with each other. A scenario proposes that the small one, NGC5195, did traverse a few times its companion and is now located slightly behind the larger M51. The iconic two galaxies of the M51 object are special to… Continue reading M51 – Whirlpool Galaxy
NGC7635, the Bubble Nebula. This strange object is the result of stellar winds produced by the star visible on the lower left, causing a shock wave on the clouds nearby. The propagation is not symmetric due to the differing density of those clouds. This picture took nearly 14 hours of 300-second H-Alpha exposures, combined with… Continue reading NGC7635 – The Bubble Nebula
Messier 16, the Eagle Nebula, from my backyard, through the large light pollution halo of Rennes. ~120min Luminance with 480s LPR subs on #Atik 314E, New Moon. #Orion ED80T on HEQ5-Pro. DeepSkyStacker3, #Gimp+G’Mic. Propelled by #KStars #Ekos #INDI.
Very small part of Cygnus’ Veil, before attempting mosaics. ~176min Luminance with 480s LPR subs on #Atik 314E, after Full Moon. #Orion ED80T on HEQ5-Pro. DeepSkyStacker3, #Gimp+G’Mic. Propelled by #KStars #Ekos #INDI.
Usual winter target 🙂 the soul of Orion’s sword, M42. Taken Feb 2018, -5°C but waxing moon and pollution peak… 15x60s #Atik 314E #Orion ED80T #HEQ5 unguided Bortle 5.
In #astrophotography, plate-solving is the process of correlating stars in the field of view of a telescope with stars in a reference catalog. The name refers to the photographic glass plates that were in use for survey catalogs during 19th and 20th centuries. By matching the relative position of light sources in an input capture… Continue reading Plate-solving the Markarian Chain.
