I have a china-made 203mm/f4 newtonian reflector telescope to sell. I bought it half years ago. due to that I am going to DIY my 254/f4.5 tube, therefore I want to sell this 203mm OTA at S$250 only. buyer must collect in Singapore. If you are interested, pls email me with your contact no to firstname.lastname@example.org. I will contact you and arrange a time with you to look at the tube. If you also want to DIY your newtonian tube, I accept international order 150/203/254/300mm main mirror, accuracy :1/10-1/20. buyer has to bear the international delivery charge.
