i dont suppose the final mirror in this state before the lense (and the lense was grubby too) was helping scan accuracy

thats what you get for 3 years use and never been cleaned cleaned and back in now

finding that removing the plastic is really helping, using 18% power i get vapour marks, 15% just dust that wipes off easily

so using 210mm/s
15%

just need to super fine tune the interval
