Tonight cloud was floating around, and with Saturn just outside, why not setup my scope?
Initial alignment was simple with my Rigel Quick Finder, but I soon found that there is a problem on tracking, the mount seems to track wrongly in the alt. direction! I guess the problem was due to the fact that, I placed the mount on the right side! I guess the Nexstar mount has an assumption that the scope should be placed on the right!
Since transparency was bad, I dare not to do the alignment again.
I guess this might be my last observation from inside home before the windows of my home got fixed, I found it rather terrible to open the window too much now.
For even simpler alignment, I will modify my finder bracket to accept my laser pointer shortly.
