Since you need to move the Dobsonian manually it is particularly important that the movement be as smooth as possible. All astronomers deserve to have it without paying any extra! The selected main mirror is better than difraction limited. The targeting faceplate displays the returning laser spot with a clear visual reference during adjustment. Product added to wishlist. But you will be surprised that many laser collimators in the market fail in this regard. This somewhat annoying effect does not occur in the Crayford focuser.
