Description

4 panels shot with Rokinon 135mm F2.

Usually the PhotometricMosaic defaults work flawlessly for me the first time through, but this framing had Rigel and the Trapezium in the overlaps.  After some frittering with the settings I found it was necessary to trim these bright objects from one panel of the joins to avoid wide color bands perpendicular to the joins.

I believe the strong single line diffraction spikes on the bright stars were caused by a cat hair which has now been removed from the back of the lens. That theory will be tested the next time out.
