Well, I'm going to try again this weekend and see how it goes. What I've done lately has

been disappointing and I've tried from the Unibrain and the DMK.

I hope to get a clear sky this weekend.

What is the opinion of the color version of the DFK 21BF04? ( I am

using the DMK 21BF04 )?

I assume its sensitivity is pretty good mostly what I loose is some

resolution from the bayer.

It has the same Sony ICX098BQ CCD in it as the Unibrain Color Cameras

do. If you removed the color bayer filter mosaic (not physically

possible so don't anyone even think about it) you would have the

exact same CCD as used in the DMK 21BF04, the Sony ICX098BL CCD.

The Imaging Source do have better electronics (lower noise) and can

push the gains up higher before the noise becomes really objectionable.

Sensitivity wise it's around 40 - 60%, depending on the light source.

It's most sensitive to green because it has 2x as many green pixels

as red or blue. Green is also the color that our eyes pick out the

most detail in too.
