Has anyone had a chance to take a look at any of the pics yet?
I spoke to Canon, and they had a look and just told me to turn on the long exposure and high ISO noise reduction options. Though I don't really want to wait an hour for a 30 minute exposure to process if I shouldn't have to. They said I can send it in for them to take a look but they probably wont do anything with it.
Also, I got Photoshop CS6 and opened the backyard nightscape RAW images using the CameraRaw plugin, and it seems to have removed the bright pixels and any blotchy noise that was visible in DPP. Maybe I should just deal with it during processing?
