      #5519242 - 11/14/12 09:25 AM

I'm siriously considering to buy Leica zoom eyepiece.
There are Two Leica's, 20x-60x, 25x-50x ASPH.
Which one is better?

My main purpose is Planetary and moon observing^^

My scope is 10" F4.8 Dobsonian.
And I'm under making 13.1" F4.5 Dobsonian.
13.1" will be my main telescope^^

Whatīs very different about them is the apparent field of view. The ASPH really is a widefield zoom, the older one is not. So if you have the money for it, the ASPH is more versatile. But itīs also heavier and wider and its range is narrower.

For planetary and lunar observation in an f/5 scope you really want to combine it with a Baader VIP barlow or Astrophysics BarAdv, though: better edge performance on the moon and a more useful focal length range.

The ASPH Zoom is considered the better of the two, but as Alexis says, its mainly due to the larger FOV, they are both great eyepieces. The ASPH though has been compared to the ZAO-IIs for on-axis performance.
