Hello guys. So after a while i got my full spectrum modified camera back, and i tried imaging with it. I took several pictures from several targets. When i was imaging the star Alnitak there was a weird rainbow pattern in the image and i have no idea what it is! i tried rotating the frame and the rainbow pattern remains at the same place in relation to Alnitak so i think i ruled out the coma corrector? Maybe? Also Alnitak is the only target that gives me this rainbow, i tried sirius, betelgeuse and several other bright stars none of which create a rainbow pattern. Any ideas what this is?
