That's real cool Steve. What filters bandpass do you use for near IR imaging? ANy links?
Thanks Marc. The filters are by Astrodon. The link is:

Basically you have infrared luminance which doesn't pass anything shorter than 700nm and R,G and B having responses centered at 850, 830 and 750nm. It's not narrow band though as the filter responses are quite broad. I've enjoyed playing around with the IR filters and of course they enabled me to image that recently discovered globular apparently before anyone else.
