Any thought as to why bright stars have this starburst..
It's a very simple imaging train.. William Optics Zenithstar 61 with a flattener, no filters.. the main lens as well at the flattener are spotless, I don't normally use flats as I have a small sensor an no dust specs.
I know with my eyeglasses if I clean them without a cleaning solution they will get similar light streaks, is it possible the same is happening with the optics? I normally use air to blow off any dust and I use specialized microfiber cloth that is for aviation FLIR equipment..
Thanks in advance...
