Heres an interesting one
As an experiment I used my new Q guider camera for a mapped colour test as it is a monochrome chipped unit

I fitted it to my 6 inch SN scope, pointed it at a hill a few kms away.
First shot through an Infrared pass filter (ir light from about 800nm and longer, no visible light)
2nd shot, I used my 7Nm Hydrogen alpha filter
3rd shot, by Baader Narrowband Oxygen 3 filter, havign to remove the camera from the scope and replace the filters each time
I then manually aligned the images with Photoshop, then assingled the colours as folows

The IR shot- red
Ha shot-green
O3 shot, blue
here is the result, I didnt even make any adjustments, what you see is what I got. Im amazed at now bright the trees came out, like a landsat image
