a 10 inch reflector telescope is easy to make....parts on ebay, $1,000 dollars....20 inch was all the talk in the 70's when sidewalk homemade scopes
got their start in california.....they make their own parabolic mirrors by hand lapping glass blanks...or set up a pattern machine that spins
slowly.....I made a 6 inch for under $150.00....now i have aperature fever....that's diameter....also on the intronet for $900.00 dollars, all the 8
inch reflectors you want. get a F5.5 to F7 for ease of finding the image(that's diameter of mirror by the length till it focuses, or focal length
divided by diameter)

ebay, baby for parts.....but not the whole scope retail-like
