echo product-name in a link

I think you’re wanting to do this:

add_filter( 'woocommerce_order_table_product_title', 'my_order_table_product_title', 10, 2 );

function my_order_table_product_title( $html, $item ) {
     return '<a href="' . urlencode( strtolower( 'http://vividcandi.net/telescope/' . $item['name'] ) ) . '">View Video</a>';
}
