1.25" Mirror Diagonal (6231)

I’ve been using this 90-degree star diagonal for a few weeks, and the dielectric coated mirror delivers noticeably brighter, clearer views than my old prism diagonal. The 1.25" size fits my telescope perfectly, making eyepiece swaps smooth and hassle-free.

The dielectric coating on this diagonal really delivers—stars snap into crisp focus with no dimming or color shift that I can notice. It’s a solid upgrade over the stock prism, and the 90-degree angle makes lunar viewing much more comfortable.

I was getting neck strain craning to look through my telescope, but this 90-degree diagonal makes viewing at the eyepiece so much more comfortable. The dielectric coated mirror gives a nice, crisp image without any noticeable light loss.
