Thanks.
Im dead keen to image M42 as well, to see how well stars that shine in IR but are hiddne in visible light go. I will try and image Barnard 86 as well to see if I can pick up stars shining through in IR light.
I took this pic of Cometary Globule 4 (CG4) not long after I got my modded camera, its a totally unfiltered image, Im wondering if it may have appeared dimmer if I had used the UV/IR cut filter.
With IR sensitivity though it does drop off further into the IR spectrum, all 3 colour lenslets on the pixels are transparent to IR light, so the sensor behaves more like a true monochrome sensor.
Definately more room for experimental imaging in the infrared
