If you bump clarity way up in Lightroom those fake star/specks show up.
Here's my go at it. I used the 60D for this one and cropped the heck out of it.
70-200mm f/2.8ii @200mm
What are all those white specks around the Moon?
Don't tell me they're stars; they can't be at that exposure.
Is your camera suffering from a very noisy sensor? Or did you add them manually in Photoshop? Or let Jackson Pollock loose on your image?
I layered in photoshop, and no, these are not 'all' stars. I bumped the white noise and de-saturated the photo.
