Here is our Space Eagle Total Destruction video walkthrough for Angry Birds Space Cosmic Crystals level 7-7. Fling the Sardine Can just west of the westmost chained boulder, calling for the Space Eagle when the Can is between the northwest planet and the chained piglet. The angle should shower the other two planets with sufficient debris to break them.
If you have an alternate strategy please feel free to leave a detailed comment below.

1. Red Bird into the right stone ball of the left most large two ball set. Red bounces off that set and hits the two chain sets to the right. The first chain set hit goes up and destroys the left most crystals with the three pigs and the other two chain sets fly to the right to destroy the little crystal plant with the medium sized pig.
2. Land the Sardine Can into the remaining chain sets (between the two stone circles of two separate sets) to the left of the right most crystal planet or if there is an open path into the planet.
Your method proved to be utterly useless, resulting in 70-80% destruction. What did work is activating the can earlier than shown in the video.
