Do I need a UV/IR cut filter?

congrats on the new camera! I have the same camera and I have never used an UV/IR cut filter. the thing is maybe my images could have some improvements. You can see all of my images on astrobin are ok without one; however perhaps I have been derelict in not using the UV/IR. Interested to read the responses myself.

If you're using it with a Newtonian reflector, no.
If you're using it with an SCT...maybe.
If you're using it with a refractor (even a nice triplet APO) -- yes.

Yes. Your stars will be smaller. It's not essential, but it's useful.

It's a good idea for all types of scopes. Reflectors or compound scopes may be more immune than refractors but if you use a reducer or flattener lens, then it wouldn't hurt to use UV/IR filter. Star shapes may look less natural if you don't use UV/IR filter especially for RGB imaging.

I added one for my refractor based on CN advice and it's an incredible difference.
First without it.
