IR/UV Cut Filters with Modded Camera?

[Astrosurf]

I tend to get a lot of red with my modded 600D. I've heard that using an IR/UV cut filter would help. Is this so? Or would it cut out Ha as well, even though it's not in the IR?

Alexx,

the whole idea of the DRSL mod is to increase the red response.

There may be minimal NIR leakage which would be suppressed with an UV/IR filter, but I'm sure the final image will still have " a lot of red"

Thanks Merlin.

Depends on which mod you had done. Did you have both the IR and UV filter removed (full spectrum mod) or just the IR filter?

As mentioned above, you want the red. That's the good stuff! If you have had a full spectrum and you are using the camera on a frac, then you will need to block the UV to avoid starbloat. If you are using a reflector, this shouldn't matter.

Thanks redmoo. I'm not sure what the mod was so will find out.

Hello, 

you can find out pretty easily if you have an IR remote control. They usually utilize a led around 900nm. If can catch your remote control "in action" then you have a full spectrum camera. If the the led doesn`t light up in the picture then you already have the UV/IR cut filter installed.

PS: In your kitchen you can also do stuff like that if your camera records full spectrum:

Hi,

Get the clip in EOS AStronomik LP filter as this will correct the colour balance to almost perfect without loss of Ha signal, this is one of the great things about this filter and was designed that way, aswell as doing what it is supposed to and cut out the LP.

Thanks. I don't have an IR remote, but I'll have a go at taking a pic of a hotplate!

I do have this filter, but I didn't know it sorted colour balance. It does create a red halo around stars which is annoying!

This must be the " Hot Ring Nebula ".

I dont get any red rings or halos, but it use with an SCT , and I have heard of people having your issue with refractors.

If you put the filter in the camera and take a daytime picture with lens, you will see how it correct the colour balance, then take one with out it. It does a pretty damn good job, which like i said before, it is designed to do.
