Geoff - thanks very much for that sequence of images. I'll certainly use those as a reference when deciding on my exposures.
Yesterday, I did some testing in clear skies. Rain overnight had cleared the atmosphere of haze, and my exposures were substantially different to Friday. I now have a better feel for how my scope, camera and filter relate to the published calculators. The unknown of course is how it will work without the filter in place.
I've also gained some experience on how much a hazy sky changes the exposure, as well as how the histogram moves with bracketing. I've setup my exposure sequence during totality and just need to see how the camera performs with a new memory card to adjust timings for the diamond ring burst sequences. I am consistently using shorter exposures vs those quoted by the calculators for the partial phases, so will adjust my diamond ring exposures in a similar fashion.
I've probably shot a thousand or more exposures testing the script sequence...
Thanks again for the advice - fingers crossed for fine weather,
DT
