I'm about to self-modify my camera, especially after seeing the increased Ha in your Eta C images - wow!
Could I ask, what did you replace the original Canon sensor filter with ? Or did you just leave the sensor filterless?
I intended on using a 2" baader Ir-Uv cut filter in the 2" focuser but do I need a clear filter in front of the sensor ? For normal photography I was going to purchase a screw-on lens X-NITE CC1 filter.
Oops maybe this should be a discussion for another forum...
