|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:
