Whats wrong here....

[chirantha7777]

ok so I messed my focus screen trying to clean it with alcohol and a qtip. I'm ordering a new focusing screen which would cost me 42usd. However for the time being I'm using the damaged screen and notice that bright objects in the view finder (a bulb) appears in doubles. Is this something wrong in my mirror or is it because of the scratched screen?

Logic would indicate it's most likely because of the damaged screen.
