Summary
| Description |
Español: La nebulosa de emisión NGC 6188, que se asemeja a dos dragones se encuentra a unos 4.000 años luz de distancia, en la constelación de Ara, sólo visible desde el hemisferio Sur.
La imagen fue adquirida con un telescopio newtoniano, cámara astronómica mono refrigerada y dedicada, utilizando filtros de banda estrecha (Sii, Ha, Oiii), todo montado sobre una montura ecuatorial motorizada. Se adquirieron 3.5 h de información para cada filtro en tomas de 3 min, y se obtuvieron 3 apilados maestros mono los cuales al ser mezclados se obtiene la imagen a color. Esta imagen es el resultado de filtrar selectivamente todo el espectro visible de luz excepto las líneas espectrales de los elementos más abundantes en las nebulosas de emisión, como lo son el Azufre doblemente ionizado (Sii), el Hidrógeno alfa (Ha) y el Oxígeno triplemente ionizado (Oiii). Esto permite que estas imágenes puedan ser realizadas desde ciudades con tanta polución lumínica como Córdoba. La paleta Hubble se conoce como SHO debido al mapeo de la señal Sii como rojo (R), la Ha como verde (G) y la Oiii como azul (B). Fecha y Lugar de adquisición: Julio 2020, Córdoba Capital, Córdoba, Argentina. Equipo Principal: cámara: ZWO ASI 1600 mm-pro, telescopio: SW Explorer 250pds+SW Coma corrector, Montura ecuatorial: SW EQ6-R-Pro, Enfocador electrónico: ZWO EAF, Rueda de filtros: ZWO 7x2" EFW, Filtros de banda estrecha Optolong. Equipamiento de guiado: telescopio guía: starguider 60/240 mm, cámara guía: ZWO ASI 120mm mini. Tiempo total de integración: 10.55 h: 70x180” lights Sii, 71x180” lights Ha, 70x180” lights Oiii. Imágenes de calibración: 100 darks, 50 flats per filter. Softwares utilizados: SharpCap 3.2, SGP 3.1, PHD2, Pixinsight 1.8.8 and Photoshop.English: Astrophotography of the NGC6188 nebula in narrowband technique and Hubble palette (SHO). The emission nebula NGC 6188, which resembles two dragons, is located about 4,000 light years away, in the constellation Ara, only visible from the Southern Hemisphere.
The image was acquired with a Newtonian telescope, dedicated cooled mono astronomical camera, using narrow band filters (Sii, Ha, Oiii), all mounted on a motorized equatorial mount. 3.5 h of information were acquired for each filter in 3-min shots, and 3 mono master stacks were obtained, which when mixed yielded the color image. This image is the result of selectively filtering the entire visible spectrum of light except the spectral lines of the most abundant elements in emission nebulae, such as doubly ionized Sulfur (Sii), alpha Hydrogen (Ha) and triply ionized oxygen (Oiii). This allows these images to be taken from cities with as much light pollution as Córdoba. The Hubble palette is known as SHO due to the mapping of the Sii signal as red (R), Ha as green (G), and Oiii as blue (B). Date and place of acquisition: July 2020, Córdoba Capital, Córdoba, Argentina. Main equipment: camera: ZWO ASI 1600 mm-pro, telescope: SW Explorer 250pds+SW Coma corrector, equatorial mount: SW EQ6-R-Pro, electronic focuser: ZWO EAF, filter wheel: ZWO 7x2" EFW, Optolong Narrowband Filters. Guiding equipment: guidescope: starguider 60/240 mm, guide camera: ZWO ASI 120mm mini. Total Integration Time: 10.55 h: 70x180” lights Sii, 71x180” lights Ha, 70x180” lights Oiii. Calibration images: 100 darks, 50 flats per filter. Softwares used: SharpCap 3.2, SGP 3.1, PHD2, Pixinsight 1.8.8 and Photoshop. |
