Narrow-band imaging with a modded DSLR?

Recommended Posts

Hi,

I know that the best imaging device for narrow-band imaging is a mono CCD, but is it possible to get decent results with a modded DSLR?

I imagine that exposures would have to be longer, which of course is not a good thing.

Is that the main drawback or are there others I haven't thought of?

Thanks

Nico

You can (I used to do Ha with the 1000d) however, because of the bayer matrix on the sensor you're not using all the pixels. In the case of Ha only 25%. Yes, also needing longer subs meaning more noise with an uncooled camera.

It can be done although most seem tomove onto CCD fairly quick if they get hooked on it. There's a world of difference.

Longer exposure with an uncooled sensor will significantly increase the noise in the image. It means an accurate calibration is much more essential which is hard to achieve when temp is unregulated.

It's possible but it ain't easy!
