If you intend also intend to use  for daytime photography as well then you need to leave the filter in. 

But if you only intend to use for astrophotography then again probably depends on what you intend to image. 

People with far more experience than myself will add more information but for sure it is not necessary to remove the filter to get good images of most DSLRs so if you have just bought it I would use it as it is at least for now.

What scope will you be using it with, will you be guiding and what do you want to image ?

Title says 40d you say 400d. You can use it as is but you will get much better results on nebulas if you have it modded.

I got my Canon 550D modified and the results are much improved as a result.

If you remove the LPF#2 Filter but leave in the LPF#1 to cut out IR, you will get improved Ha response on Nebulae.

Daytime results will have a red caste that can be removed if you have basic PhotoShop etc skills.

A Custom White Balance helps but doesn't totally fix the red caste.
