Far and away the best self instruction book on this subject that I have come across. He explains things beautifully, then goes through worked examples of each subject and finishes with practical exercises. Answers are included as an appendix, as are extracts from Nautical Almanacs.
An ideal way of keeping amused during lockdown.
Highly recommended.
