Focusing the CPC Finderscope

Although Celestron forgot to mention it in the manual, the finderscope can indeed be focused.  First, back off the locking ring behind the front cell (the cylinder holding the main lens of the finder).  Then you can rotate the front cell to achieve focus. Finally, tighten the locking ring back up against the front cell to keep it in place.

If you are having problems keeping the finderscope aligned with the main optics, you will want to read the article about Correct Installation of the Finderscope.
