Hola,

4 horas y 22 minutos, pero no de exposición. Ese fue el tiempo que le tomó a la PC con win32 y 2GB para integrar las
51 imágenes de la Canon 5D Mark II.

El objeto es Omega Centauri y lo sacamos en colaboración durante el estreno del nuevo Taka 106 de Ezequiel Bellocchio.

Procesado 100% en Pix 1.7 y todos los detalles, parámetros y foto en mayor tamaño en los siguientes links:

In English: http://proxima-sur-fotos.blogspot.com/2011/07/ngc-5139-details-of-processing.html

Participamos, Ezequiel Bellocchio, Andrés Vattuone, Leonardo Julio y Alejandro Tombolini

Saludos.
Alejandro.

Ghost nebula Sh2-136 in Cepheus
This picture was photographed on July 6-8, 2011 in the Crimea Ukraine) during the festival of amateur astronomy, "Southern Nights 2011" (height of 600 m above. sea level)
Good weather conditions, dark sky. FWHM from 1.4 to 1.9 arcsec.
Equipment: reflector S&D 254 mm. f/4.7 (New carbon tube), Mount WhiteSwan-180, camera QSI-583wsg, Tevevue Paracorr. Off-axis guidecamera Orion SSAG.
LRGB filter set Baader Planetarium. L: 20x600 sec., RGB: 10x600 sec. each filter, all unbinned.
Calibrated and processed using PixInsight 1.7. Just little final touch in Photoshop CS5.

Process workflow:
L channel:
Calibrate, star align, image integration using Linear Fit Clipping
Dynamic crop
DBE
Histogram transformation
HDRWT

RGB channels:
Calibrate, star align, image integration using Linear Fit Clipping
Combine  channels to RGB image
Dynamic crop
Background Neutralisation
Color calibration (manual, using data from eXcalibrator)
Histogram transformation

LRGB combination
SCNR
ACDNR

Finally, adjust levels in Photoshop (I have so far is more convenient)
