With the Celestron StarSense Explorer 125mm f/10 Schmidt Cassegrain Telescope, exploring the wonders of the universe is as simple as 1-2-3:

     1. Dock your smartphone

     2. Launch the StarSense Explorer smartphone app

     3. Observe the moon, planets, stars, and more

This innovative integration of smartphone and telescope offers beginner astronomers a fast and (more importantly) easy way to discover what's up in the night sky and where to view it. The StarSense Explorer app uses your phone's camera to find objects of interest and guides you to move the telescope. When the object is ready to view, the bull's-eye turns green.

Optically, the 125mm primary mirror gathers copious amounts of light to provide detailed views of the lunar surface and planetary features. It has the ability to reach beyond our solar system and view bright deep-sky objects. Supporting the telescope and StarSense holder is a basic manual yoke mount with a simple control handle that lets you move the telescope quickly and easily according to the app's direction to find your object of interest. It allows you to precisely track the object when you want to view it for extended periods. A two-section aluminum tripod provides a wide adjustable height to accommodate a variety of viewing positions and users. This makes the telescope easy to transport when you have to carry it to remote viewing locations.

        Related Questions and Answers

        Q: 1. Is the mirror parabolic? Or spherical?

        A: A large 8” parabolic primary mirror with XLT coatings helps you make the most of StarSense technology. Locate faint, deep-sky objects in seconds and see them in more detail than ever before.

        Q: 2. Hello ,. can we take images using this scope? or connect pc?

        A: There are different digiscopeing adapters for smartphones, point&shoot cameras and cameras with interchangeable lenses.

        Q: 3. Four questions, is it compatible to Samsung Galaxy? Do the lenses contain eye cups to block out external light? What the maximum degrees of altitude for viewing on the tripod? What is the maximum height of the tripod? My last telescope made it difficult if not impossible to view anything above 40 degrees and when looking I had to actually get on my knees on the ground and no eyecups.

        A: Yes it is compatible with any Android or Apple IOS smart phone. The eyepieces that come with the telescope do not have eyecups. Eyecups are not usually needed for astronomy since you are using the telescope in the dark or near dark conditions. There are optional eyepieces that you can buy that have eyecups.

        Q: 4. I have Nikon DSLR can this telescope accommodate this camera?Thanks

        A: The ïdeal scope"for astro photography would be a Cassegrain type of reflector. However, you will not finf one in the $180. price range. With that said the next best would be a reflector like the Celestron StarSense Explorer LT 114AZ 114mm f/9 AZ Reflector Telescope BH #CESSELT114R • MFR #22452 You will need a camera mount to attach to the scope.

        Q: 10. Can you see saturns rings with this? Is it clear? Also what would I need to buy to attach my Nikon d7500 to take photos?

        A: Yes, you can view Saturn very clearly through the StarSense Explorer DX 130AZ. We recommend that you purchase a T-Ring for Nikon Camera #93402 and a Universal Barlow and T-Adapter 1.25" #93640 to take short exposure of the moon or bright planets. Because the telescope does not come with an equatorial tracking mount, you will not be able to take long exposure images. A Smartphone Adapter such as the Basic Smartphone Adapter, 1.25” #81035 is also available to help align your smartphone's camera lens with the telescope's eyepiece for short exposures.The Universal Barlow lens will also double the power of the eyepieces that came with the telescope.
