<upd_detl>Aligning... ?  I hate to discard information, but ...

I think all of the following are roughly the same in meaning:
針の穴から天覗く   &lt;-- This entry
to be like a frog in a well; to make (faulty) assumptions based on one's limited understanding of something;
針の穴から天を覗く 
to have a narrow view of things
鍵の穴から天を覗く
to have a narrow view of things
葦の髄から天井を覗く
to have a narrow view of things 
管を以て天を窺う 
to have a narrow view of things

If any of these expressions was common, I'd probably feel differently.  All of these are pretty my trivia, and their meanings are more-or-less comprehensible from their literal glosses. Compare:

井の中の蛙 - 89167  "synonym"
針の穴から天覗く	93

"to make (faulty) assumptions based one one's limited understanding of something" seems like a literal translation of the daijs definition. daijs also gives similar definitions for all of the other terms above.  Wording varies slightly, but I can't imaging the nuances are actually different.  As an alternative to simplifying this gloss, we could complicate all of the other glosses.

Seemed odd in particular to have the "frog" gloss here, which I don't think is particularly common in everyday English.  (If it were, we wouldn't need a separate gloss on 井の中の蛙, "person who is ignorant of the real world"). 
It is certainly used in Japanese references to define the term, however, perhaps that's where it came from...

For a [lit] gloss especially, not sure why 覗く would be glossed as "look".  針の穴から天を覗く already uses "peek". aligning this as well. (also "the sky" vs. "the skies").</upd_detl>
