For the sky it is about 60 minutes of total exposure time at ISO 800 with the astrotrac and vixen polarie scope (with custom adapter sleeve), 60 minutes of darks, processed without edits in deep sky stacker, and finally processed in photoshop. The 24-70 2.8 II has very little coma and sharp wide across. I had a dew heater attached to a jump start battery as dew is my enemy.
The mountain was processed separately as best to look the way I saw it and to compliment the scene. The mountain was moved over onto the scene above where the landscape was blurred from the tracker. It was such a surreal environment with the mountain looming up close, then with the processed milky way popping up above it is something - nothing we can detect with our eyes.
As far as the foreground, it was a tough call. The sky was moonless with a bit of light from the hotel across the street that may have provided the light I saw on the mountain but I doubt it. Basically there was no light pollution there and no moon. Hence, I couldn't live view focus on the mountain and so I kept focus the same as the sky. Maybe I should have stepped focus as an experiment for later. The biggest thing I think is that even with the mountain at 800 iso, the sky IQ demonstrates how much stacking with darks really helps the noise for a clean image and pop. There just wasn't much light on the mountain with only the snow showing up well. Ideally I would have taken a nap in the car and stayed there until 4-6 am for a twilight image of the mountain to improve focus and noise, but I had to leave at 2am to drive back to the crossing and awaken at 7am for the family. If I were listless at 7am - trouble..... Then again one would wonder how the milky way showed up so well with a well exposed mountain scene. Maybe Jim would comment more.
