1.25" 90 Degrees Mirror Diagonal (All Metal Housing) by DVLP (DMIR0125) for Telescope - Astronomy , Astrophotography / Imaging

I read reviews online for my specific scope (celestron powerseeker 80EQ), and the consensus was that the ball shaped 90 degree diagonal mirror needed to be replaced. As it is not the best for light gathering, it was plastic, and it was the first thing one should do to improve this scope. It arrived and it was perfect! Full metal, which I wanted, because almost everything else on the scope was metal. So why not make the diagonal mirror one and the same. It works perfect for me and I would recommend it to anybody starting out with a smaller, more affordable refractor.

I am very pleased with this purchase.
