The sky was pretty clear last night, probably due to the S or SW wind which blew away the dust from mainland China. The moon was also hanging very high.
I did captured some non-tracked shots earlier, and thus would like to do something at higher power, maybe using the Sky90 instead of the Ranger. That means I'll have to use an EQ mount, since I don't have any alt-az tracking mount now, the DSX mount is having problem which is not yet fixed.
However, I tried to point the mount from both sides of the window, it still could not point the moon. It seems like EQ mount could only be used during winter from my home window.
Thinking that I probably couldn't do anything better than the first night for non-tracked shot, I gave up.
