下面这段是Mizar 68/1000跟某似乎是国产70/700的对比:
When looking at Mars trough the Skylux/Nagler, I saw a nice orange globe, not pinpoint-sharp, a little bit of chromatic aberration, but no details on the surface. I think those details were on the edge of visibility. So not a spectacular sight, but I have seen much worse. I was quite satisfied about the sharpness of the image and the chromatic aberration. As next, I tried the Mizar/Nagler combination. The sight trough this combination really made me nuts! A very sharp globe, no chromatic aberration at all and details visible on the planet without any difficulty.
My conclusion about the primary lens of the Skylux refractor: not bad at all. Sufficient for a beginner. Nevertheless, the Mizar telescope was the big winner.

这真是不错的镜子,9月前会搬家,搬完后可能就暂时不出喽。 |
