Sensor Troubles

For a few years now I’ve had some dark spots on photographs I’ve taken of aircraft in the sky. These show up when I’m on full zoom on the telephoto lens and a recent trip to Headcorn really showed this up so much so that I had to edit the photographs to get rid of those dark spots. Finally I got around to searching for a solution after I eliminated it being the actual lens. The first thing is to try blowing the dust spots out with some air. This is where my troubles really began. The guide I saw said hold the camera with the sensor facing downwards and blow the air upwards into the camera body. This was attempted but without much thought as I was using a can of compressed air and had to angle the can horizontally to get the flow direction correct. A load of propellant came out of the can and sprayed into the camera body. All of this stuck to the sensor and I effectively ruined the camera.

Another searching of the internet resources led me to find a microfibre sensor wipe that might clean the sensor enough so that I can use the camera again. I was either going to spend GBP20 or so on some special wipes or I was going to have to send the camera off for a new sensor or professional clean. The twenty quid seemed worth it before going for the Amber Level response. One day later and I’ve got the camera body open with microfibre wipes in hand and I’m trying to clean the most sensitive part of the camera full in the knowledge that I might destroy it. The process completed and I now have an OK-ish camera. I still think it needs to be sent off for a proper clean but I might get away with just that rather than having to buy a new sensor. The camera is working a little better than before and the original spots are reduced. They are still there but not as prominent. I need to go somewhere I can take photos of aircraft flying to see what the background looks like.
