Thank you, Jasem. I was not using a command to read the image prior to issuing the capture command.

I went back and double checked a previous thread (indilib.org/forum/general/13-command-lin...ver-indi-sx-ccd.html) and noted the second time through reading that there is the need to request the properties with a long time out immediately followed by the capture command.

Thus, the following works:
indi_getprop −t 30 &
indi_setprop "GPhoto CCD.CCD_EXPOSURE.CCD_EXPOSURE_VALUE=0.02"

This does strike me as a particularly nice solution. But it does work!

Python is not in my toolbox of languages, but based upon your PyINDI suggestion, perhaps it's time I look into it.
Thanks again, Darren
