Nice scope. What were the factors that caused you to choose a 1.83"
secondary? I'm building a 10" f/5.8 and I haven't decided which size
secondary to use. The 'Newt' design program indicates a 2.14" secondary
will cause some vignetting of the 75% light cone in my case, so that's
why I'm considering using a 1.83" secondary.
