    Hi, all.

    I am using STL-11000 C2 without any additional filters.
    Recently, there were too many light pollution near by my observatory.
    So i would like to use Light Pollution filter but i`m not sure is it possible or not.

    - I will buy 2" LPS-P2 or L-Pro filter .

    I attached my nosepiece and question.

    Thank you.

    Yes, a 2" filter will fit the nosepiece.
    You can also screw it in to one of the filter slots, which is probably a better idea.
    If you have budget, consider buying some narrowband filters (like hydrogen-alpha, oxygen III, etc.).
