暫時香港所見最高水平的攝影作品，也體現了Lunt LS152T的威力 8-)

只是，什麼時間看到動畫便好了.....

I think only the egress pics were taken by LS152T. All other pics were by LS80T.

Yes! One can see the differences between LS80T & LS152T. According to CaK's specification, the max aperature supported is 100mm. I guess the safety margin is enough for 105mm. I will try the CaK on 105/650 photographically and see the quality of the image. In fact if one use the CaK for imaging, I guess the aperature could be much larger. That is the margin is only for visual.
