| Description |
Español: La nebulosa de emisión NGC 3324, conocida como nebulosa Gabriela Mistral se encuentra a unos 7.600 años luz de distancia, en la constelación austral de Carina.
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 múltiples horas de información para cada filtro en tomas individuales 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: Abril 2020, Córdoba Capital, Córdoba, Argentina. Equipo Principal: cámara: ZWO ASI 1600 mm-pro, telescopio: SW Explorer 200pds+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: 16.5 h: 160x180” lights Ha, 85x180” lights Oiii, 85x180” lights Sii. Imágenes de calibración: 100 darks, 100 dark-flats y 50 flats por filtro. Softwares utilizados: SharpCap 3.2, SGP 3.1, PHD2, Pixinsight 1.8.8 y Photoshop.English: Astrophotography of the NGC 3324 nebula in narrowband technique and Hubble palette (SHO).
The emission nebula NGC 3324, known as the Gabriela Mistral Nebula, is located about 7,600 light years away, in the southern constellation of Carina. 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. Multiple hours of information were acquired for each filter in individual 3-min shots, and 3 mono master stacks were obtained which, when mixed, obtained 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: April 2020, Córdoba Capital, Córdoba, Argentina. Main equipment: camera: ZWO ASI 1600 mm-pro, telescope: SW Explorer 200pds+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: 16.5 h: 160x180” lights Ha, 85x180” lights Oiii, 85x180” lights Sii. Calibration images: 100 darks, 100 dark-flats, 100 flats per filter. Softwares used: SharpCap 3.2, SGP 3.1, PHD2, Pixinsight 1.8.8 and Photoshop. |
