Sounds like you have dust on the sensor, but you might have dead pixels. If the point is well defined that it is dead pixels, if a bubble "generally in heaven is dust from the sensor. This technique be shown to everyone. In Photoshop or similar, pull up a blank canvas and fill the screen (press the 'F' twice in Photoshop) all you need is a in standby mode can use a blank document in Word or whatever. Set your camera to aperture priority and a small opening Av f22 or so, take a picture while the camera moves around the screen, the focus is not important. Import your image and make it large, you will see every piece of dust, every hair and every pixel dead They are really well defined. If you find dust (and probably) the lens off, go clean the sensor on the menu, and holding the camera backwards to try a Rocket fan, no more than that, do not use compressed air with contaminants in them. Sensor cleaning is not as difficult as people made out, make sure your battery is full (so the shutter does not close on you without notice) and the use of these pills the proper fluid and follow Eclipse instructions.
