Coma corrector on a skywatcher 200p

[piprees]

Hi, I have a canon 40D attached to my Skywatcher 200p with a T2-EOS adaptor ring. I would like to fit a light filter AND a coma corrector. Is this possible. The light filters that clip inside cameras seem like a brilliant idea but they're sooo expensive compared to the skywatcher ones. The hole inside the T2-EOS is about 1.35 inches across and is threaded. Anybody know why? Kind regards, P.

Not sure about the filter, but the Baader MKIII CC works well, it also has a filter thread, there web site will show the sizes ect
