Hmmm, non focused star, in ep showing 2ndry not center, , Have been changing squareness of main mirror, chasing star but not changing the out-of-center alignment,,,
Now made/designed a double ring cardboard mask for inside of ota and will place it over the inside opening of focus tube , hopefully showing where reflective light is bouncing back off 2ndry to focus tube, maybe need rotation of 2ndary, looks good 90deg to main parallel path ?
Hopefully find some horizontal discrepancies ?
