Done! Thanks again for your help!
Here's a light capture of the SSAG camera ... [ https://www.dropbox.com/s/8vqfpwmy5py14jg/SSAG_1sec_1x1__frame1.fit?dl=0 ] and it's logfile [ https://www.dropbox.com/s/93zmyq9czuiayl8/SSAG_logfile_20161001175510.txt?dl=0 ]
Here's a light capture of the C8300 camera ... [ https://www.dropbox.com/s/z95fxntejwq9v8c/C8300_1sec_1x1__frame1.fit?dl=0 ] and it's logfile [ https://www.dropbox.com/s/3o8t1xmskvamnjw/C8300_logfile_20161001175725.txt?dl=0 ]
Here's a light capture using MaximDL of the C8300 using it's direct driver [ https://www.dropbox.com/s/vxvaszqtm705ktw/MaximDL_C8300_Direct.fit?dl=0 ]
... and another from MaximDL using the ASCOM driver [ https://www.dropbox.com/s/8n9dcnu9441irxw/MaximDL_C8300_ASCOM.fit?dl=0 ]
The light capture shows the same "whiteness" of the focus capture (which narrows things a bit), hopefully the FIT info will give more clues ...
