I was thinking about modifying my DSLR camera and was wondering if I send it in if they can replace the IR filter with a H-alpha filter? Or do u need to be able to shoot without the filter in as well

Why would you do that instead of a full spectrum or mono mod + H-alpha clip-in filter or something like that?

 

The clip-in filter you can at least change without having to re-mod the camera. If you want to leave it there forever, you're free to do so.

I think they sell a T-Ring in which you can screw in a 2 Inch filter.. Or buy a cheap manual 5 position filter wheel and use that.. At least that way when you are ready you can add your other filters and then move up to a EFW..

Yes I know, I know, another question followed by spend more money to fix the problem.. But this is the hobby we are in..

Permanently mounting a Ha filter in your camera is going to be limiting in a lot of ways.

 

Unless you do a mono mod, you would only be using 1/4 of your pixels (the red ones).

 

Doing things like focusing and framing will be very difficult through a Ha filter.

 

At one point I spent a fair bit of time/money getting set up with both a full-spectrum mod and a mono mod. In the end, I only use my full-spectrum mod camera (as a second/osc/travel camera).

 

I quickly (but not quickly enough to save a bunch of money) realized that a dedicated mono cooled astro camera is a way better option if I really wanted to do narrowband.
