Thanks for you anticipated response.

howdy leon,
you certainly can just remove the existing filter but don't forget, IR light will need to be blocked. If IR light doesnt get blocked, your focus will not be accurate. IR light will interfere with your focus. If UV light doesn't get blocked, you might get those purplish halo's with bright stars from your refractor
Alternatively, you can leave the DSLR without a replacement filter and just use a UV/IR 2" filter in your imaging chain.
