Cosmo... or similar is the name of the chinese 18°-cameras one single ebay seller was offering on ebay. I have saved all the images of the three models he offered from 99, 250 to 800 usd. Whats the correct naming and who is selling. other models were announced. but the seller didnt know. He was offering pinholes with integrated shutter. no-removable plates.
This cam-system had been discussed here.

I have seen it called something like sky-bow or something like that too. Would be interested to hear from anyone who has one.
