Star Tracker Advantages and Disadvantages

Advantages

  • Is capable of producing fantastic images
  • Has been named the heart and foundation of every astrophotography rig
  • Produces an effect impossible to get otherwise
  • Exposure lengths, instead of being limited to around 30 seconds, can be up to 20 minutes or even longer
  • The limitation of the 500 Rule is eliminated
  • Small, portable and lightweight
  • MUCH more affordable than an equatorial telescope mount

Disadvantages

  • Could become quite expensive
  • Depending on the model and brand, this could have a steep learning curve
  • Has several prerequisites, such as being able to locate Polaris
  • If not correctly polar-aligned, then it is nearly useless.

Evaluation

Other than the price point and potential difficulties in learning to use a star tracker, one of these is by far the better option.
