this is a great read for when you are ready for star test.

I started with 6mm series 500's then bought a 5mm LV vixen from asimov and was amazed at the improvement in diffraction rings and then in june 2007, i got to look through a 6mm radian and by habit focussed in and out and my jaw dropped at the quality of the diffracition rings during focussing.

Iwould have said I originally got a 100% improvement over the cheap series 500, then another 100% improvement with the borrowed radian.
