Hi all!

 

I used my Polaris 114 for observing Moon and Jupiter through the open window of my room (24-th floor). When I used 25 mm eyepiece (40x) in combination with Barlow (40x ---> 80x) or without it, everything was fine.

 

But I can't get sharp image with 9mm and 6.3 mm eyepieces.

 

Is it just my problem or it's a general situation ?

 

Best regards,
Roman

Open windows are better than closed but still not good. The currents will pretty much automatically cause the worst possible "atmospherics" and just like real atmospherics being that poor will limit the scope to very low magnifications. 

 

If you get it outside, and particularly once it cools down, you should see a major improvement.

You might also look at a bright star.  Get it in a good of a focus as you can, center it, use your 6.3 mm eyepiece, then defocus the star.  The should look like a target.  If the center dot and the various rings are centered on each other, then the scope is collimated well enough.  If they are not, then the scope needs some tweaks.

 

By the way, welcome to the forum!
