工作稳定了,准备继续入坑了
看了656的光学参数,发现貌似比fsq106性价比高很多啊!
有没有大佬做过详细评测对比什么的?看了下spotdiagram 为啥fra600的蓝光波段的光点大于红光段??有毒??有懂得老哥解释下吗?FSQ106的就没有这个现象
参数附上

FSQ106ED
The Takahashi FSQ-106EDX4 is a redesign of the popular FSQ-106 and is a superior flat-field super quadruplet refractor. This redesigned version features a flat field advanced Petzval quadruplet design, with extra-low dispersion (ED) glass for super color correction in the UV, visible and IR wavelengths. This optical design results in pin point star images and increased field illumination. Designed from the ground up for digital imaging, this new 4 element / 4 group design is also capable of stunning visual performance.
