I'm interested.
I have an H-alpha Lunt scope already, and a nice Herschel wedge.
Am I correct in understanding that this is mainly for photography, is for a standard telescope?

Can it be used on larger scopes than a 4" refractor? I have one, but I'd be keen to give it a crack on a bigger refractor or a Maksutov. Any reason not to? Like excess heat?
