I recently took images of Exoplanet Tres-5b Transit with my Canon 450D and an orange filter by Optec. I was looking for a "blue blocking" filter becaus it is recommended by Bruce Gary in his book "Exoplanet Observing for Amateurs". This filter clearly blocks the blue wavelengh as it does not start letting light through until around 500nm and it is available in a 48 mm size which is what my set up requires.
My results compared very favorably with the observed/published depth and time of transit figures posted on Exoplanet Transit Database .
Glad to hear you have achieved that with a DSLR. I have recently followed a couple of transits with my Atik314L+ with good results. Which scope have you used?
