Webcam For mount guiding and fits in Modernastronomy webcam to Finder adaptor

[COSMOS1256]

 

I purchased product "SPC900 / SPC880 Adapter for Straight Through Finders" From Modern astronomy since I was going to start astrophotography. My intention was to use my windows lifecam but the adapter won't fit. I have a few questions about the adapters and about webcams.

I found Toucam 2 and SPC900nc used versions, which was kinda expensive for me..... I was expecting webcams of about less than 50 dollars. Is there other webcams that adaptor fit with? And can I fit xbox liveview or Quickcam pro 4000 in this adaptor?

Also, my webcam adaptor diametor is smaller than adaptor, is there adaptor that fits my webcam or is there other way to fit my webcam into finder?

It'll be very helpful to answer these questions.

Can you post up a picture of the finder and parts that you already have.

I'm struggling to visualize which part you may need.

Cheers
