The Cutout Tool is good to have, but I would like to make a perfect circle as a hole through a rectangle, as if I was using a telescope looking at something far away. Anyone out there who knows?

Hi and welcome here π
You can find tutorials about this in the Wiki (about masking)
[https://wiki.synfig.org/Doc:Building\_a\_magnifying\_glass](https://wiki.synfig.org/Doc:Building_a_magnifying_glass)
[https://wiki.synfig.org/Doc:Basic\_Masking](https://wiki.synfig.org/Doc:Basic_Masking)
Donβt forget the main concepts in Synfig are Groups, hierarchy of layers and Blend modes π
