<upd_detl>The first reference here had a long description of this idiom.  Had the rather nice-looking translation of 覗く as "peer at the ceiling". Not sure if that is any more [lit] than "look" was though.

look -&gt; peek/peep
Also, since [lit], adding a term for 髄.

peep/peek matches:
針の穴から天覗く
針の穴から天を覗く 
鍵の穴から天を覗く</upd_detl>
<upd_refs>I have comments already on 針の穴から天覗く, but I ran into an article on this term specifically, and as you might imagine, the definitions are basically identical:

https://landofnu.com/2016/10/09/3250/
Forming opinions and making decisions on a topic based on one’s narrow views and pre-formed beliefs rather than any sort of breadth or depth of experience. Making judgments about big issues based on little information, often in a self-serving way. Having a view as narrow as what can be seen through the hollow stem of a reed after the pith has dried up.

This saying is the よ entry of the Edo iroha karuta set, and is mostly synonymous with the saying about the frog in the well.
