New features on the Porta II Mount:
"For so many years the beginning astronomer was forced to buy a mount that was unstable and almost useless when viewing at high power. More often than not, the frustration of using an unstable mount resulted in the telescope only being used for one night and being left in a closet to collect dust. The Porta mount changed all that. It is one of Vixen's proudest designs. The combination of smooth movement, rigid design and stable platform makes your first use a pleasure and will bring you back to view more and more of the night sky. The Universe Today says "The PortaMount II is quality through and through, it's not going to just fall apart on you and it would be oh-so-easy to adapt any number of other right to it just as easily as the R130Sf went into place."
