Introduction to Lynkeos

Languages English - Français

What is it ?

Lynkeos is a Cocoa® application dedicated to the processing of astronomical digital images taken through a telescope. It is running natively on Intel Macintoshes. It is optimized for vectorized instructions sets (SSE), multi-processor and multi-core machines.

Where does that weird name comes from ?

Lynkeos was one of the argonauts, the Jason's fellows who sailed on the Argo ship, seeking the golden fleece. Lynkeos was surnaturally keen sighted, hence the name of this software, hoping that this sponsorship will help it giving surnatural results Biggrin.gif.

It is to be noticed that the Argo ship sails the skies as the Carina, Puppis and Vela constellations ; among the argonauts were Castor and Pollux : the "Gemini", and Hercules. At last, Lynkeos himself roams the skies as the Lynx constellation.

How does it works ?

By stacking the best images, the signal to noise ratio is increased and details lost in the noise of individual images become visible in the resulting image.

This software accepts, as input, QuickTime®,MPEG or AVI sequences, still images, in any image format supported by Cocoa®, TIFF (8 bits, 16 bits or floating point), FITS, and also digital cameras RAW format. It generates a RGB TIFF image (8 bits, 16 bits or floating point) or a monochrome FITS image as output, to be further processed with some all-purpose image processing application.

The steps to process a collection of images are :

  • collect the movies and/or pictures,
  • collect calibration movies and/or pictures (ie: dark frames and flat fields, this is optional),
  • align the images,
  • select the best images,
  • stack the selected ones,
  • process the resulting image.
