Linking Two Queries From Two Database Using Temp Table

I am using SQL 2008 r2. I have two SQL Queries from 2 different database but they share one server. I need to linked these two SQL Queries as they share the same Primary key which CustomerID see example below

Query 1

Database::Student
Select StudentID , FName, LName
From Student

Query 2

Database ::Finance
Select StudentID,Tution
FROM Payment

I need to be able combine two query which come from two database but they share one server.I would like to use two temp tables so that I can perform a left / right join to retrieve the data by linking two queries using primary id which they both share ( StudentID)

Summary : I have two DB's on the same server. I have two simple select queries for each DB which work correctly.
