Fresnel lens webcam - good enough to plate solve?

[furrysocks2]

I've just ordered a 50mm focal length f/1.4 C-mount CCTV lens to play with. While searching for "50mm lens", a few fresnels popped up.

Full of aberrations and useless for imaging, no doubt. But then again, given how well plate solving seems to do with rubbish input, any opinion as to whether a fresnel lens projecting onto a webcam might result in a solvable image?

With a 1/4" webcam, 6um pixels, 640x480, I calculated the following:

Likely not, just wondering.

Got the 50mm dia 40mm focal length through the post - difficult to hand-hold a fresnel lens in front of a webcam and maintain colimation and focus, but I can definitely get some straight edges from across the room to come into focus - the glazing bars on the window or the edges of the lampshade, for example.

I wonder then... with some apparatus to hold it all together, "good enough to plate solve" might be possible.

Why? Fun.
