With a small amount of practice, the optimal focus can usually be found within a few minutes. The following guide provides assistance with this task. anonymous@undisclosed.example.com (Anonymous) Tue, 10 Mar 2026 13:29:27 +0000 https://polaris.astro.physik.uni-potsdam.de/wiki/doku.php?id=en:ost:fokus&rev=1478819523&do=diff Focusing A good focused telescope is essential for each successful observation, especially if deep-sky exposures shall be taken.
