Again, I went back to that playground last night.
No wind tonight, better seeing... I guess around 6/10.
I setup the Nexstar in the wrong direction, I thought it will work, but then it fails to track properly, in short, it tracked with exactly opposite direction. I believe two points alignment would do, but since I do only solar system alignment, so it won't know unless the initial position is fixed.
At first I guess there might be something wrong, and I redo the alignment but things kept on wrong. Finally, I reversed the mounting direction of the tube, and thing got right by then.
There were no visible bright star on the sky due to the heavy light pollution, so I don't have any good target for collimation, I couldn't use high power diffraction pattern on dim stars. So I just randomly picked a star, defocus a bit and collimate briefly with it.
I setup my scope where there were many flying insects, and my head was buried in the plants during alignment, so bad. So I really have no mood on doing good collimation or focusing.
