M78 for ESO Processing contest. WFI camera on 2.2m telescope

M78 nebular complex in Orion

 

La Silla 2.2m MPG/ESO telescope, Cassegrain focus (F=8009mm).

 

5x3min Red, 3x3min Green (V), 3x3min Blue(B)

 

FWHM = 1.4"

 

Camera: WFI 8k x 8k mosaic CCD.

 

Image was calibrated, and Stacked from RAW data via IRAF software, composed/ white-balanced in Iris, and post-processed in PhotoShop.

 

Post processing was made in 50% scale (4228x4114) because image was quite oversampled (nothing to lose in 50% scale) and my PC is terrible weak for 67Mpix 16-bit image's multi-layered photoshoping :-)

 

This is a sample in ~12% resolution.

Large version is here (50% of original FITS, 12Mb)
