Third partty monochrome CMOS for DSLR?

[pixueto]

It has been discussed before. It is impossible to debayer a CMOS sensor as it is very difficult to eliminate the bayer matrix evenly, right? Also, you will be destroying the microfilters which lay on top of the matrix.

My question is this: is it possible to find a third party CMOS monochrome sensor compatible with some canon DSLR models at a reasonable price? That could be a solution as all it would be left to do is to replace the original canon CMOS. Maybe someone in the forum with the technical expertise could shed some light on this matter. If there are not third part suppliers, surely there is a market there in the astroamateur community.

Does it make sense what I'm saying or is it just a stupid idea?

Thank you

For CCD cameras, manufacturers make the CCD chips (Kodak, Sony, etc.) Third parties then build cameras with the supporting electronics, coolers, bodies, etc. In theory it would be possible to change parts in these cameras if they are compatible (e.g. change a one-shot-color sensor for a mono one). In practice this would be difficult as the chips are usually mounted directly on the boards not in sockets (to eliminate unwanted noise, etc.)

For DSLRs, the CMOS sensors are generally manufactured by the camera manufacturer (Canon, Nikon, etc.) They don't tend to re-sell them and sadly they don't make mono versions of the sensors.

Although cam manufacturers don't acknowledge it, the Sony CMOS APS sensors are used in a number of popular DSLRs - just check the pixels arrays to note the unusual similarity.

As noted astro-cam makers draw from available sensors and the resultant cams with their special features like controlled cooling etc cost much more, due to the tiny number of units made, compare to regular DSLRs - that's life
