Outdated Links makes Price Too High
While the tables are valuable the resources are not. It would be a better Kindle value of you could save the feature tables for field use.
This book was published in 2005, while the objects in the sky haven't changed, making this still usable, the data is old, the media links are all obsolete and the descriptions of equipment are so old they look like equipment from the 20th century and not modern binoculars.
Recommendation, buy used and use the charts as the links are irrelevant, examples of which included Palm OS, AOL links and apps which no longer work. Every link I tried ended up with a 404 error.
Even the Kindle price should be reduced to below $10. If the tables could be exported or printed for field use this book would have a lot more value today, (2018).
