Michael, There was no problem using the H-Alpha filter. The exposure time for guiding was 7 seconds through the filter, but still the guiding errors were under 1 arc second with the CGE mount. There was no blooming at all.
Regards,
Gary.

How did you find using the H-Alpha filter? Any issues with guiding? Any blooming on the 15min exposures?

Cool. Good to hear. I always fancied the idea of getting a set of Ha, OIII and SII filters instead of RGB. Only problem is deciding whether to get 2" or 1.25" ones.
