Telescope
   F Ratio = f/10.00
   EFL =  2500.00
   Curvature of Field =  265.462
   Mirror Separation =  530.769
Primary f/3.00
   Diameter =  250.000
   Radius of Curvature = 1500.000
   Aspheric K = -1.07435
   Hole Diameter =   60.480
Secondary f/3.80
   Diameter =   82.418
   Radius of Curvature = -626.374
   Aspheric K = -4.19052

See where it says "Hole Diameter" under the Primary section.

As far as I can see, you have not given any of your design parameters
anywhere, so I cannot comment.
