Most of the modified camera's are using the Baader ACF or BCF filters(or none at all) which claim a 98% transmittance figure at Ha, which is also claimed by Baader to be 5x the trans of the standard Canon filter.
Canon claimed it's 20Da had 2.5x the trans over standard, and the 60Da has 3x the trans over standard.
I think that could be the cause of the very red images.
According to
this graphic I found on the interweb, the Baader would have ~4x trans (98%) over standard(25%).
Would be interesting to see the curve for the 60Da's filter, guessing it would have approx 75% trans at Ha
