Description

This Hubble pallette image of the Pelican Nebula was taken with a Baader Modified Canon T1i DSLR.

For this image I extracted the Red channel in the Ha and SII RAW images and the Green channel in the OIII RAW images.

Then I did the same for the Red channel or Green of the bias, dark and flat frames. in order to produce the master red (or green) dark, flat or bias. The mentioned channel of the RAW files were calibrated with these masters

This procedure produced a very clean (for a DSLR) Ha, OIII and SII images. Then those monochrome images were combined using the Hubble Pallet R (SII), G (Ha), B (OIII). After that, the image was processed using the usual work flow.
