Thanks acropolite, I am not using a coma Corrector/field flattener on the Camera and my Telescope manual said I required this filter when using it with EOS DLSR's. A friend of mine said it would fix this common problem with these type of scope/camera combinations. I am just waiting for it to turn up at the shop as it is on back order, I have also ordered a 2" 4 position motorised filter wheel (Orion) with appropriate filters. I was told also a IR blocking filter would be useful?
I have previously been using a Meade DSI II Colour CCD.
