这镜子要被吹上天了，国内订购的人也越来越多，看看美国佬的评价：
There is NO false color or fringing, even at 220X (3mm Nagler zoom). The collimation is also PERFECT at all magnifications. And there is no visible image degradation at any magnification I can reach (220 is as high as I can go!).
I've been observing a Palm tree about 100m away (the sky is still cloudy) and the trunk of the tree has a very rough and stringy bark, so I'm looking at very small, delicate details, and they're tack sharp!
白天看100米外棕榈树220倍无色差，无色边，细节清晰锐利画质无下降。
SO...what CAN we do tonight? CHECK FOR COLOR ALONG THE LUNAR LIMB!
Before we get to that, let me just say that the lunar views are simply stunning. Razor-sharp (even in mediocre seeing)! With contast as good as I've seen from ANY 5" scope. My favorite combo is the 6.7mm ES eyepieces which generate almost exactly 100X and frame the entire lunar disc with plenty of room to spare.
OK, OK....COLOR!
THERE IS NONE FOR ALL PRACTICAL PURPOSES!!!
At magnifications up to ~160X (all that can sanely be generated in this lousy seeing). There is NO limb fringe, unless you are LOOKING FOR IT.
Sure, I can FIND a hint of yellow if I place the bright limb at the extreme right edge of the field. And a hint of purple at the extreme left edge. But you have to LOOK for it. And anyone who is not as obsessive as some of us would probably never even notice it!
晚上看月亮，用的ES6.7mm这个垃圾目镜（我说的，不是作者说的，这垃圾目镜估计配啥主镜边缘都会有色边），160倍实际观感无色差，无色边，除非在边缘仔细找能找到点。 |
