Baader Prism Star Diagonal
I bought this 1.25” Star Diagonal to go with my Celestron C5. This diagonal utilises a prism rather than a mirror to turn the light by 90 degrees. I think that this makes the diagonal more robust? I was quite surprised by the great build quality of this device - and it works perfectly for me. Great buy!
