Celestron CG-4 Dual Axis Motor Drive
Upgrade your Omni XLT mount with this Dual-Axis Drive system from Celestron! There are two motors, one each for the right ascension and declination axis, a hand controller with North, South, East & West push buttons, and a power pack that holds household batteries.

Celestron Polar Scope for CG-4 or Omni Mount
Make polar alignment a bit easier with this traditional polar scope made for the Omni CG-4 mount. The etched reticle in the polar scope works for both the Northern & Southern hemisphere and the eyepiece focuses for the sharpest views.

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 25 mm eyepiece, for 40X magnification. 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!

Apertura 10mm Super Wide Angle 1.25" Eyepiece
The Celestron 102 Omni XLT comes with a 25 mm that yields 40X magnification. If you add this 10 mm eyepiece to your collection, it will magnify by 100X. Add a basic 2X Barlow to the mix and you’ll get 200X with the 10 mm eyepiece, and 80X with the included 25 mm.

Celestron 40" Telescope Soft Case
Store and transport your Omni XLT telescope in this soft case with room enough to hold the whole enchilada…telescope OTA, mount & tripod! There are separate areas for each large component, and small accessories can be stored in the external zippered pocket or bonus padded accessory bag! A great investment to keep your telescope dust and ding-free for years to come.

Apertura 1.25" Moon Filter
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.
