Celestron StarSense Explorer LT 80AZ

Worth knowing before you buy

Is the mount stable enough for this telescope?

The mount is the weak point of this package. Multiple users report noticeable wobble and 3-4 second settle times after focusing or moving the scope, especially when using zoom eyepieces or heavy accessories.

How smooth is the focuser out of the box?

The focuser comes overly greased with what one user described as 'car with square tires' smoothness. Several owners have disassembled it, removed the excess grease with mineral spirits, and replaced it with synthetic lithium grease (Super Lube), which dramatically improves operation without full replacement.

Should I upgrade the eyepieces and diagonal that come with it?

Multiple users report the included 25mm Kellner is acceptable but the diagonal and red dot finder are poor quality. Most recommend upgrading to better Plossl or Svbony eyepieces and a quality prism diagonal, which together cost around $100-150 and significantly improve views.

Is the StarSense tracking system easy to use for beginners?

Yes—users consistently praise the smartphone app for being intuitive even for non-technical people and for dramatically speeding up object location. Unlike GoTo systems, it requires no battery pack, alignment routine per session, or menu navigation, making it ideal for casual observers.

Can I put the StarSense tracker on a different, better mount?

The tracker is attached to the OTA on the 80mm model, making transfer to other mounts possible but requiring custom fabrication work. However, replacing just the tripod with a heavier unit (while keeping the included mount head) is straightforward and significantly improves stability and reduce settle time.

Is this a good first telescope choice?

Multiple experienced users recommend the 102mm refractor version over the 80mm, citing dramatically better views of planets and deep-sky objects while still being portable and beginner-friendly. The 80mm is better suited as a secondary grab-and-go scope or for transferring the StarSense system to another telescope.
