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

Interesting colour concept.
The window has a strange colour about it.

Very interesting image you have there, so if we never knew that trees were supposed to be green than red would look pretty good.

I suspect trees actually reflect more in IR than in the visible spectrum. If our eyes had better range, not much would look green due to being overwhelmed by that additional range.

I'm tempted to try a similar shot, with blue mapped as blue, green mapped as green and IR mapped as red, just to get an impression of what foliage would end up looking like. I suspect it wouldn't be much different from your shot.

Nice detail mate and interesting colours.

It looks like that guy's house roof has started to collapse in the middle.:eyepop:

Cheers :thumbsup:
