I'm a fan of "100 problems in Celestial Navigation" by Leonard Gray.

https://www.celestaire.com/product/100-problems-in-celestial-navigation/

I like the fact that each chapter considers a segment of a plausible trip (you're sailing from San Francisco to Alaska...), walks you through the process of choosing which stars to sight for both morning and evening sights, and considers real-world problems ("at dawn, you find that it's cloudy, and you can only get sights of these two stars...").

An added bonus is that the book contains the requisite tables. That does mean that all of the trips take place in July or December of 1993, and that there's a suspicious coincidence of trip segments with 40°N and 40°S, but it turns out that a lot of interesting trips do intersect the 40th parallel, and it's nice not to be juggling books.

Naturally, problems constructed by the generous souls on this list will be far finer, but if they run out of steam or you want a nice sequence of problems that's already constructed, I suggest giving Leonard Gray a try.

As always, apologies in advance for any information in this message that is misleading, incorrect, malicious, hostile, or vituperative!
