I saw the blue desk version for about £70, and a field version for about £140 odd. The ad shown shows the field version to be less than half at £63. I suspect an error in pricing for the field version in that ad. I didn’t notice the error in the title.
You obviously like star atlas’s. After reading all this wonderful advice from all the posters, I’m spoilt for choice. I can see a few purchases ahead. I’m glad you got prompted 🙂
