Using Lucam to smooth Bayer Array artifact with Skynyx 2-1c Color Camera
|
Lucam recorder (http://www.astrofactum.de/Astrofactum/LucamRecorder/index.htm) offers several different formats for image capture. I
had been using either AVI (limited to 8 bit color) or TIFF (which can take advantage of the 12 bit color depth of the Skynyx 2-1c camera).
But with either, the Bayer array of the one shot color camera caused a herringbone artifact Imaging small targets (Mars is currently only
14" diameter) this herringbone/grid artifact shows in the final image.
Below is a test image of a building with prominent vertical and horizontal edges, a blow up of an area to show the artifact in an image
made from TIFF data and the separate R G and B channels.
The grid/herringbone pattern is mostly from the Green channel

If you capture in the proprietary SER format there is a batch utility that will later convert the SER data to other formats such as TIFF or FITS. When doing that
conversion it can also do a Bayer to RGB conversion which substantially removes the grid artifact:

From SER with Bayer to RGB conversion
So at the cost of one extra step (SER to FITs or TIFF conversion) that conversion will
let you remove the grid artifact from the Bayer array
