Yea and btw any good objects for me to look through my scope/10x50 binos today? Prefably before 11pm and DSOs

i used a 50x magnification without barlow. It looks like a blurry blob of light through the eyepiece.

Haejae, if possible please try posting some pics of the stain for us to see..will be hard to advise without jumping to wrong conclusions. Also today's (2/11) weather looks good, skies seem very blue for now. You can try doing a star test on a bright star to check collimation of your scope. Regards ...

Haejae, can you tell us more about the issues? 1. What do you mean by cannot focus? I thought previously you did look at a star? Did you try pointing the telescope to a far away building? Is this related to your suspicion that the telescope is out of collimation? 2. What kind of stain? Fingerprints...

Besides, when I view a star, it seems as if it is impossible to focus. What is the problem here?

And one last thing
The circumference of my primary mirror seems to be stained. I noticed this one week after purchase. Should I send it back to astro scientifics ?

Just wondering is it possible to polar align a scope in Singapore?
Have heard a little about drift alignment but my scope doesnt allow the declination to be below 20 degrees

BTW for a 127/1000 scope what is the best eye piece to observe large DSOs such as m31, dumbbell nebula,m42 ?
