Cleaning the CCD

The MK2 camera is designed with a protective shutter door that seals the CCD inside a dust free

environment.  In most cases, cleaning should not be required for many years.  To test your camera

for dust we suggest stopping the camera down to F22 with the longest lens you own.  Lay the

camera on it’s back so the lens is pointed at the sky..  (You may need to prop something under the

pan motor.)  Shoot about 20 degrees worth of  sky at F22 while letting the motor spill freely.  Shoot

at 100% resolution.  Examine the image closely for horizontal lines.  If you see soft colored lines

running across the image you most likely have a dust particle on the CCD.

To clean the CCD first remove the front plate from the camera.  Then slowly and gently slide the

shutter door all the way open until it stops.  This will expose the CCD.

  

Once the CCD is exposed you may try to blow the dust off the CCD with canned air.  I

MPORTANT:

Always hold canned air right side up and test shoot a couple of times before blowing on the CCD

because the liquid propellant may come out in the first spray.  Always hold the can upright!  

If

blowing air on the CCD will not remove the dust you may try wiping the CCD with a clean camel

hair lens brush.  

The brush must be completely clean! 

 If you have touched the bristles on the brush

it may leave oil streaks on the cover glass.  Gently (very light pressure) wipe the dry brush from top

to bottom and do not stop until the brush has cleared the bottom of the CCD.  

Do not apply

pressure to the glass.

  The idea is to sweep the dust off the glass in one continuous motion.  After

you have wiped the glass with the brush then be sure to blow the glass again with canned air to

remove any fibers that may have stayed behind.  

As soon as you are done cleaning gently and

slowly close the shutter door.
