TPO 90 Erect Image Diagonal - 1.25"
Tired of getting on your knees to use your refractor of catadioptric-style telescope? Then stop breaking your back or craning your neck... TPO is here to help!
The TPO 1.25 inch 90 degree Erect Image Diagonal accepts all 1.25 inch eyepieces and fits into focusers (either 1.25 inch in diameter or a 2 inch focuser with a 2 inch-to-1.25 inch adapter) that accept 1.25 inch barrels. It automatically places whatever eyepiece that's put into it at a 90 degree angle for more comfortable viewing! And what's more... The image remains correct. The view stays exactly the same as if you were looking at it unaided - right stays to the right and left stays to the left. No reversal of image!

Good service and price matching.
I am well pleased with the item. Good quality!
Great for star hopping
While most correct-image diagonals are used for daytime terrestrial viewing, I wanted one to facilitate star hopping when using a typical star atlas. I have used this diagonal with 80mm and 102mm refractors that are also equipped with a RACI finder. This diagonal makes star hopping a breeze. Views are crisp and bright with no more chromatic aberration than a typical mirror diagonal. I would have given the diagonal a 5 star rating, but I'm waiting to see how durable it is (the housing is plastic rather than metal).
Using the 90º diagonal.
I've been using the OPT 90º ***** Image Diagonal it looks fine and works great this is a very good product.
