Okay, so silly me went and bought a Orion Mirror Diagonal Dielectric (1.25") from Bintel for my 10" dob...
After reading the little manual that came with it, one line caught my eye:
"not designed for newtonian reflectors".



How I hate my self sometimes...
Waste of $109 bucks,plus another 10 on p+h.
Even worse, I had saved up to buy this item
Considering it is of no use to me, the only thing left is to see how much return I can get from the purchase.
The item is brand new, still in package.
Have only taken it out to look at it.. and then sadly put back into its box after reading the instruction manual.
I paid $109 from Bintel and would hopefully like to give it to someone who actually needs it for $90 inc P+H to Australia.
So again, selling for $90 inc P+H to Australia.
Please PM if interested.
