The Orion Pentaprism 90-Degree Diagonal ($199.99US) is a non-inverting, non-reversing 1.25-inch diagonal. Unlike typical star diagonals, it does not produce a mirror-reversed image, which can make navigation and referring to star maps difficult while observing with your telescope. But unlike common correct-image diagonals, there is no image degradation caused by […]
Orion Telescopes & Binoculars’s innovative Premium Linear BinoViewer ($499.99US) is so named because it employs a sliding linear housing for adjusting the interpupillary distance (IPD) instead of the traditional folding body. That matters, because the folding types are more prone to collimation problems, whereby the two barrels of the binoviewer […]
