Here is the same Unfiltered image before and after processing. It helps to remove the Halos.
Oh, and add spikes in the next pic  |
The halo is probably because you are using a refractor. The IR is not corrected like the visible light. This is why older SLR lenses had a IR focus adjustment when you use IR film. I would think that if you use a reflector that focuses all wavelengths at the same spot the IR halo should disappear. I have tried this with my VC200L. I put a near IR filter in and took pics with my CCD and the focus is the same as visible light.
