I purchased a Canon 50D Modified (IR665nm Filter fitted).
It looks like the mod was cocked up and the eBay seller has disappeared (Shock Horror)

.
Can anyone advise me?
There are apparitions appearing on all subs and darks taken with the camera.
Could it be the filter or do you think the sensor has been damaged?
I thought it could use DeepSky Stacker to remove the apparition by using the Darks, but this has failed.
Please HELP!!!!
