Lunt B1200 Cak Module

[Martin_S]

Lunt B1200 Cak Module in perfect condition less than a year old.

I hardly used it as I prefer to do High Res H-alpha and White light Imaging.

Selling for $1700 shipped Australia wide.

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?
