Your In-vu telescope viewing telescope can be set up to accept donations for you cause.  

In-vu viewing telescopes can be configured for coin operated and non coin operated operation. The viewing scopes can also be set up to accept donations from users. You can even place a plaque on the viewing scope that encourages users to make a donation and/or educate them about your cause.

In most cases great benefits can be achieved for your causes.

With either base you can customize the donation plaque with your own special message.
