Radians vs. UO HDs

How do these compare? I have the HDs and love them but am considering Radians for the eye relief and compatibility with Dioptrix.

I think you will find the Radian to easily perform as well as the HD. The Radian is a warmer coating but it shows details very nicely on planets. It is a nice EP.
Rod and I compared the UO HD, UO standard, Radian, TV T-6, Pentax XL and the Pentax won with the Radian falling to 2nd. But we both agreed that the Radian gave better details than the UO Orthos, plus of course the eye relief was much better.
Another inexpensive alternative would be the TS or BO Planetary EPs, which are on sale for $59 each and you can not beat that price! Plus, they are very close to the Radian when you look through them. They are a cooler coating, so a little more neutral.
