Lunar X warning

[willis]

Two years already! The Lunar X can only be observed at a particular moon age for a few hour! Last time when I observed it, the moon age is 7.6. This evening we will have chance. But I missed my DMK 21 at school! So only visual!

有沒有準確時間? 我遙控西藏天文台拍拍它。

[willis]

I guess now!

[社長]

done!

20:57拍攝的，但現在滿天薄雲，月面對比度很低。

[willis]

Good! If there is no cloud, I guess the X would be more clear. Anyway, would u mind if I tune ur photo to make the "X" more clear?

[willis]

u are lucky. u can barely see it because the moon age is 7.786. Last time when I saw it, the moon age was 7.615.

下午回來睡了一覺沒看Astrocafe，否則若早一個小時以上拍會更精彩。

除月食當晚多雲外，12月另外有半晚像今天的全天薄雲，看來這時節西藏的晴天率是極端的高，最少90%以上。

Push, push & push. The X is more obvious, but other details are lost.

看到就可以了，始終目前的設定並沒有以拍月面為優化，或許二月份我再前往時會加些東西上去，用300牛反拍。

Sorry I can't get it...could anyone point out where is the "X"? Thanks.

You should get a high magnification 'sunrise at X' animation.

And a 'sunrise at Plato' please for me.

[社長]

要待二月份裝了濾鏡盤及DMK31才成，口徑是300，你看合成焦距多少? 我可以用barlow或powermate配合一下。

木星土星火星最好8000mm以上，但月面又太長了。
