Celestron Sky Maps and Planisphere
This water resistant sky map does double duty! On the front is a northern hemisphere planisphere that rotates so you can figure out what constellations are up for a specific date and time. Inside are seasonal star maps that display where bright stars and celestial objects are located, with info broken down by constellation. Recommended for anyone who wants to know what's up in the sky at any given time, this guide will serve you well for many years to come!

Apertura Astro Vision Red LED Flashlight
A red flashlight keeps your eyes dark-adapted for the best views! Use it to read star charts, look for accessories, or get around in the dark. A must for any amateur astronomer!

Celestron 1.25" Moon Filter 18 % Light Transmissio...
You won't believe how bright the moon is through a telescope! A Moon Filter will dim the light, just like sunglasses do, so you can see more details on the lunar surface. The moon filter threads onto the barrel of all included eyepieces and any other astronomy accessory you buy later that has a 1.25” barrel.

Apertura 2x 1.25" Barlow
A 2X Barlow is one of the most popular telescope accessories available because it doubles the magnification of any 1.25” eyepiece you use with it! This telescope comes with a 20 mm & 10 mm eyepiece, for 35X & 70X magnification, respectively. Double those numbers by adding a Barlow to the mix, and for every eyepiece you buy thereafter, you ‘ll have two magnification options instead of one!

Celestron X-Cel LX 7 mm 1.25" Eyepiece
The Celestron 70 AstroMaster LT comes with a 20 mm and a 10 mm eyepiece which yield 35X and 70X magnification, respectively. If you add this 7 mm eyepiece to your collection, it will magnify by 100X. Add a basic 2X Barlow to the mix and you’ll get approximately 200X with the 7, and 140X with the included 10 mm eyepiece.
