Design Objectives
  • Easy assembly

Our goals required a critical look at all of the designs available - even those that were not easy or inexpensive to produce.

 Portaball 12.5 inch f/5

The 12.5-inch PortaBall, like the smaller 8-inch model, delivers outstanding visual performance while still being a highly transportable scope featuring quick setup and knock down.  The same process has been applied in design and re-engineering, with the following features:

  • An anodized aluminum support base
  • Innovative truss attachment system that allows for faster assembly and dis-assembly
  • Improved reliability with our new battery box and wiring system
  • Custom molded top and new truss attach points provide a cleaner look while reducing weight at the top end
  • Our new secondary cell incorporates an intuitive collimation system that helps you maintain optimum collimation at all times


Whether first-time user or seasoned observer, you'll appreciate our attention to detail and ease of use: hallmarks of all PortaBall models.
