Yes I cut my own glass...pretty easy to score and snap microscope slides using a regular glass cutter...

Also by using slides, you can create a stack to get the right thickness...if you have to....(mine worked using 1 glass piece and 2 pieces of slide film)...slight quality loss due to the stack, but not really noticeable with such a cheap camera.

I plan on replacing the cheap IR solution with a Wratten gel when I can afford one to cut up...

Yes the image has been post worked starting from the RAW image data, that I cheated my camera into supplying me.

here is what the above image looks like untouched...straight out of the camera. shot using the auto settings...
