RGB filter help

[rawhead]

I now have the 'better' set of baader RGB filters that have integral IR block.

I was using a seperate IR block on the camera which doubled up quite nicely as a dust filter for the ccd chip.

Can I carry on using the IR block on top of the IR block the RGB filters already have or should I get a plain glass filter instead?

They are only £13.49 here: Astro Engineering AC535 1.25&quot BK-7 plain glass filter for web-cam and CCD nosepieces Will this do?

You can spend £30 at Modern Astronomy...

This is for planets using a DMK21.

You can use the IR/UV cut as the dust blocker - with the RGB filters.
