Meade Digital 90mm X 1000mm fl Tube with High Quality Fully Coated Objective Lens! I know quality optics and this is one of them. The 1000 mm focal length and 90 mm objective ratio is the sweet spot that will not give blues and reds fringes that shorter focal length scopes refract light at different points. This comes as is without a focus system.
