That's why I tried the Schuler, to see if I could find a cheap way into H Alpha solar imaging.
I cannot remember the tech details from the filter, but a search revealed the following details: Schuler - H-Alpha 1.25" 10nm Bandpass, 656nm Narrowband CCD Imaging Filter.
Anyhow, it didn't work; either in colour or B&W mode.
