Description

When its cloudy, its processing time.

Stacked random old data, to work on my processing and Surprisingly I'm pleased with the result.

Went through 14 stacking sessions, with about 900 images, stacking multiple combos of sessions. Then inspected the 14 stacks and inspected each one after a quick stretch.

Finally narrowed them down to 2 stacks and worked on processing them both simultaneously up to a certain point, until i had a clear winner.

This stack is a blend of different gain (300,252,135) settings and exposure times between 30,60 and 300, using calibrated and uncalibrated data (most of these were test shots or sessions).

What I am certain of is the total integration time of 12990s (3.6h)
