For a bright image - a coated mirror
- The mirror has had everything that is possible optimised, within this p.rice range, to ensure you enjoy a bright image - even at higher magnifications. It is the link between your eye and the telescope - and is hence just as important.Sometimes you do not want to have to re-install a filter every time you use a new eyepiece. Perhaps you might want to observe the Moon today with a range of eyepieces - but with the same filter? That is also possible due to the filter thread provided in the star diagonal.
