NGC 5128 in infra red, full moon present

Howdy
Had a go at seeing what NGC5128 looks like in infra red.
5x5 mins ISO 800, 850nm infra red pass filter 10 inch f5.6 scope, modded 350D, coma corrector, takes last night with bright full moonlit skies. A bit dissapointing, obviously 5128 isnt that bright in the infrared.
I will have to compare visible light images and see if stars are penetrating the dust lane more.

wow you can see where the other wavelengths of light make up the image

Fascinating. I'd be interested to see what difference the IR pass would make when viewing something like Bok globules, which are dark in visible light yet often contain young newly formed stars within. Great idea using the modded camera in this way. I've read somewhere that a modded 350D can accumulate almost as much light in IR and UV as it does in the visible spectrum. It would be neat if some targets (like maybe Bok globs) could deliver up nice pics not available in visible light.

Come to think of it wouldn't a modded camera without an IR pass filter deliver a mixture anyway of visible and IR data. So if you took a pic of a bok globule the stars in there would be visible in your pic anyway whereas in an unmodded camera they would not ?

Great fun. Again, fascinating.

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

well captured scott. I managed to capture M42 lately during the early hours but only got 2 x 84 second exposures before the sun came.
