Home Accessories Diagonals Telescope Diagonals For Astronomy StellaMira 1.25 Inch 90 Degree Di-Electric Diagonal
This premium upgrade diagonal is noticeably superior to stock diagonals supplied with most telescopes!. A fantastic quality 1.25 inch 90 degree Star Diagonal that features a durable di-electric coated mirror that has undergone a high-reflectivity multi-coating process that enables it to reflect 99% of the gathered starlight for exceptional brightness and contrast! (Most regular diagonals typically reflect 90-95% of light). The black-anodised metal body features a non-marring compression-ring eyepiece clamp and a tapered 1.25" nosepiece (less likely to fall out if the focuser's fixing screw loosens). The nosepiece is threaded for 1.25" filters.
