The main reason I know of to get an ED refractor, is to have both wide
fields, and high power out of the same scope. For wide fields of view, the
achromat 102mm F5's and F6's are good enough for us lowly amateurs. If
they
can't get it down to near 600mm, then it seems like a waste of effort. At
near 900mm, I'd rather have a DGM Optics OA4, or a similar performing
standard newt on Dob mount with no color whatsoever at any power.


The OA4 is still the best deal out there. Far better than what Orion is
offering and I haven't even looked through it! The OA4 dob mounted is less
than $1000. It's going to cost you $1500+ to fully outfit the Orion scope.
Your done with OA for under $1000. Not only that, absolutely no color,
unobstructed views that will knock your socks off. And I've actually only
looked through a 92mm scope not even the full 4" OA!
