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.


Hi,

4 hours and 22 minutes, but not exposure time. It was the time that took to the PC with win32 and 2GB to integrate

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)

The pelican in the Pelican (IC5070):

http://www.astrophotogallery.org/member-galleries/p7866-ic5070-pelican-nebula.html

2.8 hr LRGB
Scope: APM 130/780 f/6 LW CNC II
Mount: Takahashi EM-200 Temma2
Camera:SBIG ST-2000XM Astrodon Gen2
Location: Henry Coe State Park (SF Bay Area), California
Dates: 7/30/11, 8/2/11
Exposure: L:10x8min RGB:3x7x4min(2x2)
Acquisition S/W: CCDSoft v 5, TheSky6, ASCOMTemmaDriver
Processing S/W: PixInsight v 1.7, Photoshop CS2

Processing:
Calibration in PixInsight (Vicent Peris document)
Registration of calibrated lights with StarAlignment
Stacking with ImageIntegration
RGB:
ChannelCombination
Background Neutralization
Dynamic Crop
DBE
ColorCorrection
HistogramStretch plus HistogramTransformations (2)
L:
Dynamic Crop
MakedStretch plus Histogram Transformations (2)
Very slight CurvesTransformation
DynamicAlign with RGB
LRGBCombination
HDR Wavelet Transformation 4 levels only
ACDNR small scale (2,3) only
Extract Luminance and apply as mask for Saturation increase using
CurvesTransformation/Saturation for strong boost to stars
Invert mask and give very gentle saturation boost to H2 in Pelican
Take 16-bit tif to PS CS2 for final cleanup and printing:
Carboni 'make stars smaller'
Very gentle final curve with some raising of the background to survive jpg conversion
Some highpass filtering in high-SNR areas where the data supported it  (Tried AWT in PI
to accomplish the same goal but was unsuccessful - maybe next time).
Print & make jpg with sRGB profile
(Working toward doing everything in PI but not quite there yet).

Hope you like it.
