May I ask - are you using a partial ERF with the 6" SCT along with a Herschel wedge and continuum filter?

Thanks Ken.
All our white light images are taken using the Baader AstroSolar Safety film of 5.0 neutral density. According to the Solar Astronomy book, this film is so close to a Herschel wedge, it's hard to tell the difference. To get a full aperture ERF of any other kind at 6" is going to be quite expensive. We find that on most occasions, it is the seeing that stops the effective use of 6" of aperture.
