Hi again Dave
So to cut a long story short I have two laptops, one runs Windows and the other Ubuntu.
It occurred to me last night that I had done my startrailing stacking on the Windows laptop last April and sure enough there in the recycle bin were the subs!
So I can oblige your request and shown below is the full stack complete with two vapour trails!
Sods law dictates that one went straight past the pole star .. while as you can see the other leaves like a scratch running down from the top just left of centre.
It is a moot point whether to keep the vapour trails or to have the gaps in the star trails. I prefer the gaps especially in this case where the region around the pole is effected.
Cheers
Chris
