Hi Cristian, It was a lovely night the day before so I actually got outside to do some imaging for a few hours, and put the mirror off to last night. I downloaded figure xp and I will have a play tonight with it. Looks more complicated than the other one I have but does so much more. I will give you some figures from my mask as well as my figures. I don`t know how accurate they are so will repeat them tonight again. I will need help in this last step to touch up the mirror and what stroke to apply.
I find it hard to read the outer edge as I have to keep moving my head from side to side to see the shadows and also the narrower window makes it hard as well. My measurments are the average of 3 lots, as they varied a bit on the outer zones. (need much more practice at this!!!
).
Anyways let me know what you come up.
Best regards Gary
