What are the advantages and disadvantages of a modern alt-azimuth telescope mount compared to a German equatorial mount?

We're replacing an old telescope and debating between mount types. The alt-az seems more intuitive for student use and is often less expensive, but I'm concerned about field rotation for our introductory astrophotography labs. The German equatorial is the classic choice for tracking, but is more complex to polar align. What should be our deciding factors for a mixed teaching and public outreach role?

Having managed a teaching observatory, I've seen this decision firsthand. For a student-focused environment, I often recommend a modern, computerized alt-az mount. They are simpler to orient, have no counterweight hazard, and startup is faster key for short lab sessions. The field rotation issue for imaging is real, but for introductory work, short exposures of bright targets like the Moon or planets are fine, and software can derotate stacked images. A German equatorial is superior for serious, long-exposure deep-sky imaging, but the time spent on precise polar alignment can frustrate beginners. Prioritize robust, intuitive operation for your primary educational mission.
