Hello,
I have now tested the interval shooting functions of the TC-80N3 using the modified cable connected to my Pentax *ist DS, and the DSLR operations appear to behave in accordance with the TC-80N3 instruction manual.
All I need now are some clear skies.
Cheers
Dennis

David Ratledge’s web site which provided me with the motivation to build a custom cable.
