    Hi,

    I was seriously considering of replacing my GSO RC 12″ with 14″-16″ Orion Optics AG Newton or something similar. Can you give some review of mechanical quality and need of re-collimation

    And if you dont mind, some pictures of scope.

    Thank you

    -Jussi Koponen

      Hello -Jussi I find the AG14 to be a very stable instrument. I have
      collimated it once (with cats-eye tools) and even after moving to my new location collimation held. The other thing to mention, is that focus is also very stable. I have the Orion in-house Baader steel track type of focucer and find it works well with the AG set-up. Free to contact me again here or though FB instant mail if you have any other questions. https://www.facebook.com/moonrocksastro
