Hi, I recently captured a few night sky shots at relatively high ISO (1600 - 3200) range 20-30 sec exposures using Oly 9-18 at 9mm and f4.0. I processed the images in LR5, and used Noise reduction etc. to make these images "acceptable". Can any of you please help me determine, if I am doing something wrong in processing or do I need to take EM5 in to the dealer and have the sensor checked. From reading this forum I know the EM5 is supposed to perform very well at high iso and longer exposure. You can see larger size image here. Thanks for your help.
