yes there is. You have to create your own ccd camera in the file "ccds.nam" for
an english language Guide. The explanation how to do this is at the end of the
above mentioned file.

As a starting point copy the line with your main camera and give it a new, not
already uses ID number. Then you have to add the offset and size of the guider
chip. This will need some trial and error in your case, because you have
different focal lengthes for your imaging and guider telescope. The units given
for the offset are the width and height of the main chip.

I hope this information is sufficient for you to start with.
