I took photos of Moon last night with my iphone 6s. 10 of them are stacked to produce the final picture below. Indeed it is better than single ones. This is the first time that I use "registax" to stack pictures.  

Interestingly, I found a question mark "?" on Moon. Better to look after a rotation (see below).

And the best is to see other people's professional work (from Baidu, see below). I have to say we have to rely on professional tools to observe the objects in the sky. Anyway, it is still awesome experience when my tool is only a mobilephone.
