I have the ASI 178MM (for Solar) with my Daystar Ha.

The Mono camera has no IR filter (unless I am mistaken) and I removed the IR cut filter from my NexImage 5 camera understanding that imaging the Sun was better without them.

Therefore why would you add an IR blocking filter (other than to reduce heat) to a diagonal, surely that defeats the puropse of not having a filter in the camera ???, and under 80mm it is not needed anyway in the scope

Thanks
