About this product

Model:  stellamira_diag_90_d_125
Part Number:  K1.25N-AB

Noticeably superior to stock diagonals supplied with most telescopes! 

This premium quality 1.25" 90º Star Diagonal 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.

StellaMira have delivered a well made and optically high quality dielectric diagonal for a very reasonable price, and I can push my scope to its magnification limits without any loss of image quality due to the diagonal. Well worth the investment.
