This is the 2nd part of my NB test with a lot of integration time with SAMY 135mm.

Tha HA lights were made with debayered NEX5. -> perfect resolution

The O3 lights were made with modified NEX5.
a mix of blue(33%) and green(66%) out of the RGB bayermatrix are used generate monochromatic O3 result. --> 3 out of 4 pixel (red is not used)
--> the resolution is less and noise much higher compared to debayered NEX5. but it works of course.
