Trying Long Daylight Exposures

By #8, I assume you mean an eight stop ND filter. Correct? Did you establish a proper exposure first, before adding the ND stack? An ND filter isn't to darken an exposure, although you can do that. It's to allow a longer exposure, slower shutter speed, while giving a proper exposure. Don't think I've ever seen a cyan cast from one. What was the proper unfiltered exposure?
Yup.... a 8 stop & a 4 stop stacked with a CP filter.... I composed and set my initial exp. values at 1/80 sec., f22, ISO 100 & then added the stack. I then took a series of exposures starting at 2 sec. and then adding 2 sec to each additional shot.

Not to thread-jack, but is this the best way to get to the proper exposure with a ND filter?
I've noticed that when I'm at 8 stops+, looking through the viewfinder, I can't see anything - it's much too dark to try to use the light meter for correct manual settings once the ND filter is in place.

All the stuff I've read so far follows a similar thread... Use Live View to compose and focus. Lock the focus and then attach the ND filter. There are apps to convert the exposure time based on the # of stops. I've only tried this once myself so I'm still figuring it out. Here's another of the shots I took on my 1st attempt.... It was really windy so I got blurring w/ some of the trees which I did not want but hey... that's how ya learn!
