Do some reading to decide what you want, remove for full spectum, or remove and replace with a Baader cut filter to limit the spectrum to 400 - 700nm, replace low pass with clear glass or leave it, etc. Before you do it make sure you examine the photos from modified cameras using the different filters (or none) to see what the spectrum will mean to your results. Some people don't realise that there is a lot of Ha out there and the red can really overwelm other colours. There was an Eta Carinae image from a modified camera posted today in the Beginners Astrophoto forum.
