Camera Modification

Last year I purchased a Model PC165DNR Camera from Supercircuits to go into
a Meteor observatory of my own making. A few weeks ago, I disassembled the
camera and peeled off the IR filter from the sensor. This ruined its Color
Fidelity but boosted its sensitivity which is spectacular. The peril in
doing this is that any particulates inside the camera make their way onto
the sensor. The filter allowed the particulates to accumulate far above the
focal plane (the sensor), removing the filter brings anything on the sensor
window in focus. The sensor is so tiny and difficult to reach, cleaning away
anything stuck to the quarter inch sensor window becomes next to impossible.
I used a camera lens blow-bulb, which helped but there is another problem.
The IR filter was attached with glue which is so close to the sensor that
attempting to clean the sensor, smears this adhesive onto the sensor.
