Hi,

I do not own a CaK filter but I would say why not ?

What is your fear ?

I found this but I do not understand why they limit it to 100mm aperture ¿?

and look here where they offer in accessories a CaK filter

I think you'll be fine as long as you're not tracking the sun for hours at an end.

I've come across that 100mm maximum before, so as Mark says, keep the tracking-time down as much as possible and inspect the module regularly.
The B1800 is an expensive piece of kit to get damaged.
