Hi David -

Maybe you want to consider a monochrome camera and filterwheel? You would 

notice the increased sensitivity of the monochrome DMK cameras over your 

ToUcam. 

Adirondack Astronomy and Scopetronix are two good sources for the 1.25" 

Cmount nosepiece. 

best wishes -

Alan

My old ToUCam (USB) has died and my iBot (FW) is OK, but no

better than OK, on a 'scope, so I'm thinking about buying an

Imaging Source DFK 21AF04 color FireWire camera. I would

appreciate help with the following questions:

The product list at 1394imaging.com also shows a DFK 21BF04,

which differs from the DFK 21AF04 in that it has "Trig" and I/O

(and costs a bit more.) What is "trig?" I assume it means

"triggering," but I don't know what that means outside of the

oscilloscope milieu and I don't know if these features are something

that I need.

This camera is not listed as supported on the Milton's site, but

its siblings, presumably very similar, are listed. Is it a safe guess 

that this camera will work with Astro IIDC ?

The Imaging Source site says these cameras have a "C/CS" mount.

What is the name of the nosepiece needed to mate this camera

to a 2" port (or  1-1/4" reducer) on an SCT and who sells it?

Finally, I note that this company is in Germany. Does it take a long

time to get one of these cameras? (I'm thinking about going to

AstroFest on 20 September and would like to have it by then -- my

first use would be guiding with Equinox 5.)

Many thanks,

David
