The red response would also help with an Ha solar scope....
I have a FULL spectrum modded 1000D - both filters removed (used for spectroscopy).
To allow the continued use of standard camera lenses I added an Astronomik CLR clip-in filter to the body. This corrects for the loss of backfocus. Works well.
