I feel sure this must have been noted before, (but not by me). 
I was out last night looking for Nightjars, the full moon rose over the horizon of trees shortly before sunset and was looking particularly fine.
The trees were about 2-300 yards away and the adjustment on my binocular focus to change view between the moon and the treetops was negligible.
I'm aware of the optical illusion of the moon looking closer than it is at times, but how does it fool a piece of glass?
Transparent sheet silicone and solid lactulose-based animal growth-inducing derivatives (cheese) have a well-known affinity to each other in both traditional faerie and modern plasticene lore. The use of the correct grade of sheet silicone product in the objective would of course lead to a negligible difference in the apparent distances involved; the moon, when viewed through a glass, changes its molecular constitution instantaneously, and for the time-span involved it also occupies a spatial placement only a short distance from the viewer; the moon really is made of cheese and it really is only just above the treetops ...
You weren't imagining it!
