Thanks Steve,
There are a couple of reasons that offset the advantages of NIR imaging.
First of all amateur CCDs generally have limited sensitivity in IR/NIR range.
My ST-X10ME is one of the better cameras, its QE is around 65% at 0.75 microns but drops to 30% at 0.9 microns. The NIR filter starts from 0.7 microns.
Secondly NIR is absorbed by water vapour. NIR imaging is best suited for high altitudes.
Regards
Steven
