前晚天氣預測好天，雖然大大個月，但心痕想試試支SW120開光！當晚先玩月面和土星，然後打左隻深空！講起來玩了幾年天文攝影，都未拍過土星！先上張處女作土星，用Registax處理行星的技巧笨拙，睇住先！

器材：SW120ED with Baader 2.25X APO barlow (effective focal length 2025), DBK 21, AVX
後製：Registax 6, 疊加500張內最佳的80%

再用PS做大一些。

我想你用這鏡拍月亮會滿足感大些。

但不加平場，直接用軸上解像度拍星系，也會很好玩。

忘了是否改了Feather Touch的?

Yes! I knew it and shot already. I imaged the moon without flattener.

Yes, it is the SW 120ED hyper tunned with Feather Touch focuser by you.

900mm若發揮得好，可以拍得很精采，那些目標也不用加平場鏡了。

Yes! Sometimes it is boring to have focal lengths of a few hundreds. In fact, 900mm shouldn't be too difficult. Whether there is a necessity of using a flattener, it depends on the size of the objects. In case of moon, it is not necessary.
