Found the wavelet for TIFFs in registax. Works quite well.
I also checked the codec I used with IC capture and although I used Y800 for the acquisition I used another one for saving the AVI and somehow ended up making a color video (out of the mono cam) so it must have halved the res and stuck a bayer pattern in there which is what popped its ugly head when sharpening. I did another test this morning with the right codec and all is well. Much better. Pfeewh... for a sec I thought the DMK21 would be too low res to do decent solar imaging.
