The sun today - PST comparison with SDO data

Clear skies so time to observe the sun with PST 40. One big prominence at 11h and smaller ones at 4h and 9h. I made a comparison with data from SDO and the result is shown below. I must say that the comparison is very good. My picture was made afocal using a 8-24mm zoomlens and edited using CS4.
