Our Take
The Sky-Watcher Esprit 100mm is an excellent option for those looking for a step up from the smaller 80 mm scope. With the dew shield fully retracted, the 100mm has nearly the same length as the 80, making it just as compact and portable, but with more aperture. With a very fast f/5.5 focal ratio, the Esprit 100 is a traveling astrophotographer's dream.
