The diffraction pattern of the 8″ LX90AT with the broken corrector plate
The image of the Hadar (Beta Centauri) through the broken 8″ LX90AT. Look, the star image is no longer pinpoint.
Saturn delivered by the 8″ LX90AT with the broken corrector plate. It looks like the Saturn is being engulfed by a black hole.
Now, the main character~
Did you ever try to break your scope before? I doubt you dare. I maybe the first LX90AT user with the cracked corrector plate.
Here the story begins.
If anyone remembered my previous post about disassembling the LX90AT, you should know why I removed the corrector plate. Yes, I dropped a toothpick into the OTA from the visual back. All of the nightmare started from here. I bought a Purosol Optical (PO below) and their microfiber cloth as I planned to clean the corrector plate. In the end, I cleaned the primary mirror as well because the PO claimed that the solution was enzyme based and would not hurt the coating. That’s true, just that the microfiber cloth left quite a lot of fiber behind.
