Advice sought on lens f.l. for webcam to image whole Sun

Hi,

I would appreciate advice on the above.

I have a Phillips ToUcam which I want to webcast the entire disc of the Sun (I am getting ready for next years partial eclipse). Even with a focal reducer, the Schmit Cassigrain F10 is too long for the whole image of the Sun to be captured.

I figure I either get a new camera ($$ ouch..) with a bigger chip or perhaps I get a camera lens and adaptor for the webcam. I am assuming a camera lens would be cheaper but I don't know what f.l. to get. I have noticed that you can get a 80 - 300mm lens for a few hundred dollars. I don't want to waste my money so I thought I would seek some advice.

Regards,

Paul Floyd.
