Hi Tim
Because I shoot in RAW rather than JPEG, I'm stuck with whatever lens distortion I get. Stacking doesn't really work with anything less than RAW.
It was more an experiment to see what needed fixing and figuring out how to do so. Thanks for the suggestions, I've made the following changes for tonight's attempt:
- using my 24-70mm lens instead, as it has vastly less vignetting and is much, much sharper in the corners. Also shooting at f/4.5 rather than f/3.5.
- taking 10 x 1-min tracked subs, at two angles rather than just one (10 subs each angle), so the total movement in each angle is only 10 mins rather than an hour.
- also taking a static shot at each angle; I'll combine all three static shots and then will mask out the sky in the two upper shots, to replace it with the two stacked shots.
- And yes there's no wind tonight! I totally didn't take offense - I knew it was a dumb idea. I just wanted to try it all out and see what kinks needed straightening out.
A lot of work but hopefully it'll be worth it...!
