About this product

Model:  stellamira_diag_90_e_125
Part Number:  K1.25T-H

Noticeably superior to stock diagonals supplied with most telescopes! 

This premium quality 1.25" 90º Erect Prism Diagonal features a high-quality prism that turns upside-down views right-side-up and gives correct left-to-right orientation.

This is particularly useful for daytime terrestrial use.

The black-anodised metal body features a non-marring compression-ring eyepiece clamp and tapered 1.25" nosepiece (less likely to fall out if the focuser's fixing screw loosens).  The nosepiece is threaded for 1.25" filters.

Stella Mira 1 1/4" Prism Diagonal

I bought this for my daughter to replace the el cheapo plastic bodied item that came with her Celestron Starsense 102mm refractor and wanted an erecting prism so as to not confuse her at this early stage! The StellaMira item is superb, really well made and solid, noticeably brighter than the stock item too. Very pleased overall and superb service from FLO.

Erecting Diagonal

As someone new to astronomy I found the left/right reversed view in a star diagonal too much to cope with. This makes it much easier and is just the same as you see with the naked eye. I cannot tell if it transmits slightly less light than a good star diagonal, but, if it does, for me its worth it. I highly recommend it for other beginners or experienced observers who like an easy life. Appears to be solidly made and high quality.
