Diego’s very nice personal processing of the data was awarded with an
Image of the Week on the Astro Imaging Channel:
and Diego Colonnello’s site:
In this tutorial, all data will be calibrated with
100xbias all channels
20x darks all channels
20x flats blue channel
20x flats green channel
9x flats red channel
and from all flats and darks, a Bad Pixel Map is created.
Then all channels are processed and integrated automatically. A RGB composite is made and a very quick post-processing is done with star color calibration.
All integrations will be fully compatible for making a composite as a result from the automatic multi-channel processing.
The tutorial shows how the multi-channel data will be calibrated
and integrated automatically, per channel,
ready for the RGB combine tool to make a RGB composite.
