Our take on the NexStar 102SLT Computerized Telescope with SkyPortal WiFi Module and NexYZ Smartphone Adapter

The NexStar 102SLT is a 102mm f/6.5 refractor on a computerized GoTo mount, bundled here with Celestron's SkyPortal WiFi module and NexYZ smartphone adapter. The refractor needs no collimation, and SkyAlign gets the mount tracking in minutes, so it suits beginners who want to find objects rather than hunt for them. The kit adds app control and phone-based imaging that the bare telescope does not include. Against 130mm tabletop reflectors it gives up light grasp but wins on simplicity and portability; against smaller 70–90mm GoTo scopes it shows more detail on planets and the Moon.

About the NexStar 102SLT Computerized Telescope with SkyPortal WiFi Module and NexYZ Smartphone Adapter

Become an instant astronomer with the NexStar 102SLT computerized telescope, NexYZ 3-Axis Universal Smartphone Adapter, and SkyPortal WiFi Module kit! You get everything you need to explore the night sky, find your target quickly, and capture what you see. It’s the perfect solution for beginners, families, or anyone looking for a streamlined setup. All three components work together for an easy, intuitive, and highly portable observing and astroimaging experience.

NexStar 102SLT Computerized GoTo Telescope

The NexStar 102SLT is a favorite among both beginners and experienced observers. Its high quality 102mm refractor optical tube delivers bright, high-contrast views with no collimation required. The fully computerized SLT mount with SkyAlign gets you aligned in minutes, then automatically locates and tracks thousands of objects to keep them centered as Earth rotates. A lightweight build, quick-release components, and a stainless steel tripod make it easy to take anywhere, offering dazzling views of the Moon, planets, and bright deep-sky targets.

NexYZ 3-Axis Universal Smartphone Adapter for Astroimaging

The NexYZ smartphone adapter makes it simple to capture what you see through the eyepiece. The three-axis adjustment system allows you to precisely position your phone’s camera over the eyepiece, eliminating guesswork and ensuring clean, evenly illuminated images. Compatible with most smartphones and 1.25" or 2" eyepieces, NexYZ securely clamps into place for steady, repeatable imaging sessions. With NexYZ, you’ll be capturing and sharing your discoveries every time you use your telescope.

SkyPortal WiFi Module

When you plug in the SkyPortal WiFi Module, you take control of your stargazing sessions in a whole new way—via your smartphone! You can browse a massive database of 100,000+ celestial objects or explore an interactive planetarium view, all within the SkyPortal Powered by SkySafari™ app for iOS and Android. Once connected through the AUX or Hand Control port, the module creates its own secure WiFi network and pairs with the app. Explore the sky visually and tap any object you wish to view. The telescope slews there and begins tracking. Next, you can view detailed information or even listen to audio descriptions as you observe. Not sure what to look at next? Take a guided Sky Tour within the app! Astronomy has never been so user-friendly.

Questions and answers

Is the NexStar 102SLT good for a beginner?
Yes. SkyAlign alignment is forgiving, the mount finds and tracks objects for you, and the refractor never needs collimating. Expect to spend a little time learning the hand controller or app.
Can I use it for astrophotography?
It works for short-exposure Moon and planet shots with a smartphone through the NexYZ adapter. It is an alt-az mount without an equatorial wedge, so long-exposure deep-sky imaging is not practical.
Do I need the SkyPortal WiFi module?
No. The hand controller runs the scope on its own. The module lets you control and align from a phone or tablet, which many people find easier than button menus.
What can I see with a 102mm refractor?
Craters and maria on the Moon, Jupiter's cloud belts and moons, Saturn's rings, and brighter deep-sky objects like the Orion Nebula and Andromeda Galaxy. Faint galaxies and nebulae need darker skies and larger aperture.
Does it need collimation?
No. Refractors hold their alignment, so the 102SLT is ready to use out of the box, unlike Newtonian reflectors that need occasional mirror adjustment.
What comes in the box?
The 102mm optical tube, SLT GoTo mount and stainless steel tripod, hand controller, two eyepieces, a star diagonal and finder, plus the SkyPortal WiFi module and NexYZ smartphone adapter.
Where is the NexStar 102SLT Computerized Telescope with SkyPortal WiFi Module and NexYZ Smartphone Adapter cheapest?
