Interesting concept. Would love to know how it works.

What about buying a lens from a bulk supplies and mounting it just in front of the lens. I wonder if that would be an inexpensive substitute.

I have no real photography background so I have no idea if this would work, but have learned by doing and reading so as to do my own timelapse, like this video:

I would be great to find an easy, inexpensive way to get the entire sky.
