Joining the imam during the additional takbeers
Question

If I join the imam in the Eid prayer after he has started the takbeers after takbeerat al-ihram (the takbeer with which he starts the prayer), should I say the takbeers that I missed after the imam has said takbeer?.
Praise be to Allah.Shaykh Ibn ‘Uthaymeen (may Allaah have mercy on him) was asked: What is the ruling if I catch up with the imam when he is praying the Eid prayer, and he has said the additional takbeers? Should I make up the takbeers I missed or what should I do? 
He replied: 
If you join the imam during the takbeers, then you should say takbeerat al-ihraam first (the takbeer to start the prayer) and then follow the imam in the remaining takbeers, and you do not have to make up what you missed.
