To build this telescope, I bought a piece of glass over an inch [2.5 cm] thick and eight inches [20 cm] wide and had a glass cutter make it round.
Lai izgatavotu teleskopu, es nopirku aptuveni 2,5 centimetrus biezu stikla gabalu, kura garums un platums bija 20 centimetri, aiznesu to stikliniekam un palūdzu, lai izgriež no tā apli.
