INTRODUCTION

Congratulations on your purchase of the StarSense Explorer Dobsonian (SSE Dob) telescope. Your SSE Dob combines large

optics with the exciting StarSense Explorer dock and app to make finding and observing all kinds of astronomical objects fun

and easy! You’ll be able to locate faint deep-sky objects—galaxies, nebulae, star clusters and more— and place them within the

field of view of the eyepiece in seconds. The large primary mirror collects lots of light, enabling you to see details in objects that

you have never seen before.
Before you take your StarSense Explorer Dob outside for your first night of observing, we recommend reading through this

manual. It will help you to better understand the features of your telescope and know what to expect.
