NOw then, you know that I'm a newbie and know absolutely nothing about Astronomy so humour me and explain whyit is that when NASA launches a space telescope they are all mirrored devices?
Seems to me if they are good enough for NASA they are good enough for me:) or am I being totally silly about this Cornish Pastiche?

I may one day buy one of these APO's for low importance stuff like transits of NIBIRU hehehehe

Yes that is completely true that NASA do indeed use mirrors
for nearly all of their most important telescopes.
However this is where any resemblance ends.
The quality of the mirrors that they use are so far removed
from any that you or i have ever used,that i lack the
articulation to discribe.
They are really optically perfect,they take years to polish
and cost millions of $.
So yes i would be happy with a NASA spec mirror Cool
