Very good work.



Since you have a lot of manual skill, I suggest some alternatives for improvement this:



1) buy a cheap pair of binoculars, for those Chinese or Taiwanese, and use one objective. Maybe you need to mount the lens on cardboard.

2) You can enhance easily and cheaply the spherical aberration of your cheap lens: take a flat glass, an o-ring with outer diameter equal to or slightly lower of the lens; build a sandwich lens / o-ring / glass; fill the space between the lens and the glass with clean glycerin or alcohol; seal the joints with silicone.

You can replace the o-ring whit a seal of car's oil filter, but you must wash it very well.

The result will be not perfect, but will be better.
