Another new PixInsight process tutorial is now up on Light Vortex Astronomy. This one aims to instruct the reader on how to produce a seamless mosaic out of several images with an overlap between them. The procedure makes use of StarAlignment to produce a rough mosaic used to register all the individual images, followed by GradientMergeMosaic to produce a seamless end result. Also discussed is how to make best use of the settings provided to minimise seams and remove problematic stars that appear pinched at the edges. A PixelMath technique to remove pinched stars is also discussed. To read the tutorial, follow this link to it.
