Eyepieces feedback

My feedback for the following eyepieces (used in SCT Meade LX90 8" and Dobson GSO 16"):

* University Konïg MK-70 25mm 70º
* Vixen LV 30mm 60º
* Astro-Tech Titan Type II ED 40mm 68º
* Televue Radian 14mm 60º

* University Konïg MK-70 25mm 70º:
Great for both planetary and deep space. On a Dobson, Jupiter shows amazing. The cloud bands are perfectly visible and the definition of that bands are impressive.
High contrast in the SCT, no chromatic aberration in any of both telescopes.
Very punctual stars, even in the SCT.

* Vixen LV 30mm 60º:
Good option for deep space, even for a 60º aFOV.
Not a good performance in the Dobson, but quiet good in the SCT.
Very punctual stars, but, maybe not enough contrast for deep space.

* Astro-Tech Titan Type II ED 40mm 68º:
A not very known brand in Spain, it was the "star product" of our last astronomical party... Nobody knew it, but everyone enjoyed the spectacular and sharpness images of this eyepiece.
In the Dobson, amazing. In the SCT, also incredible images.. high contrast and very punctual stars.

* Televue Radian 14mm 60º
Very very good eyepiece, especially, for planetary. Jupiter, in both telescopes, amazing.
High contrast even for deep space. M27, M57, M31, M33, M104, ....amazing, beautiful!!!!

New (for me) eyepiece.... Vixen LV 5mm Lanthanum

Good performance in my LX 90 8" for planetary, good sharpness and definition and high-contrasted images.

Great value for the price!!
