I bought the Astronomik ProPlanet 642 BP IR Pass filter and got to try it out with my 8" Meade SCT and my ASI224MC.  I have to say, the sharpness of my images is better than what I have been getting (and probably could have been even more so had I spent more time on focus).

 

Although, when I run the videos through AS3, the don't seem to be very colorful.  Tuning wavelets in RS6 doesn't help with the colors, but what's really odd is when I auto balance the colors in RS6, the image looks like a monochrome shot instead of a color shot.

 

I'm not sure what's going on - any pointers?  Previously without the filter I got a lot more color.

Well, colour is related to the human vision and so it is made of red (no IR) + green + blue. If you put a red/infrared-pass filter on, you get a monochrome image because there is no green and blue anymore. No suprise here :)

Does this camera have IR leak and need an IR "cut" filter??? I don't use this camera but was wondering.

Yes, that camera needs an IR cut filter for imaging color. And as stated above an IR pass filter will only let IR light through and will result in a monochrome image.

Good idea. I've found that it improves color and sharpness in my ASI224.

Seeing is better in IR than other colors of light. Because IR refracts less in turbulent air than the other colours.
