Brief update,
I went to Jamaica at the weekend. On the outbound the sun was almost due south for the whole cruise, so I produced a lot of parallel LOPs, I did not bother to transfer them as the crossing error would have been very big.
The return at night was much better, and I got to within about 30 miles. Using the above mentioned stars The main problem at the moment is shooting technique. As I have other duties, I do not have long to acquire night vision, the mirrors are not perfect and my rubber eye cap needs some work.
However I will keep trying, I have also just come across Astron which is brilliant.
