- Different category: a manual telescope with a phone-guided finder, not an imaging smart telescope. Its image score reflects eyepiece views.
- Celestron's spec sheet gives limiting magnitude 13.1 and highest useful magnification 307×.
Specs are compiled from manufacturer pages, Amazon listings and independent reviews, and may change with firmware or production runs. Confirm what's in the box (tripod, solar filter, case) on the Amazon page before buying.
Celestron StarSense Explorer DX 130AZ video review
Video by finderBinder on YouTube. Independent creator content, shown as a reference. It is not part of our scoring.
The Celestron StarSense Explorer DX 130AZ is not a smart telescope. It’s a traditional, manually pushed 130 mm Newtonian reflector with Celestron’s phone-guided finder: your phone sits in a dock, recognizes the star field and shows arrows that lead you to each target, and you look through a real eyepiece. We include it as the honest alternative for people whose real goal is planets and the Moon live, by eye. It costs about $499.95 on Amazon (Nov 12, 2026), sold by Amazon, so check today’s price. We haven’t tested it ourselves; this review uses Space.com, BBC Sky at Night and Celestron’s spec sheet.
Who it’s for (and who should skip it)
It’s for families and first-time observers who want to see Saturn’s rings, Jupiter’s cloud belts and lunar craters with their own eyes, with help finding things, at a smart-telescope entry price.
Skip it if you want colorful pictures of nebulae and galaxies. It has no motor, no tracking and no camera, so faint deep-sky objects look gray and dim by eye. For photos, a Seestar S50 Pro (about $999) or a Seestar S30 Plus (about $474) is the right tool. Skip it too if storage is tight: it weighs 18 lb complete, with a full-size tripod.
Viewing in practice
Space.com’s review (by Damian Peach) rated it 4 out of 5, and BBC Sky at Night also gave it 4 out of 5. Space.com’s main caveat is magnification: the supplied 25 mm and 10 mm eyepieces top out at 65×, and Mars needed a separate Barlow lens.
That’s a solvable limit. Celestron’s spec sheet gives 130 mm of aperture at 650 mm focal length (f/5), limiting magnitude 13.1 and 307× as the highest useful magnification. On planets, aperture and focal length are what count, and that’s why a 130 mm reflector at the eyepiece beats a 30–50 mm smart scope on detail. The trade-off is that you nudge the tube to follow the target, since nothing tracks.
Deep-sky objects are visible but subtle. Bright clusters and the brightest nebulae show well from a dark site; from the suburbs, most galaxies are faint smudges. Our smart vs traditional telescope guide explains why stacked images look so different from eyepiece views.
App and workflow
The StarSense Explorer app is free with no subscription. Your phone clips into a dock above the tube, and its camera looks at the sky via a mirror. The app plate-solves the star field to work out where the telescope is pointing, then shows arrows until the target is centered. A conventional StarPointer red-dot finder is included too.
Once found, you track manually with the slow-motion controls on the alt-az mount. There are no batteries to run down beyond your phone. Celestron backs it with a 2-year warranty.
What you’ll need beyond the box
- A solar filter. The Celestron EclipSmart filter for 127 mm and 130 mm reflectors turns it into a safe white-light Sun scope for sunspots. Measure the tube’s outer diameter before ordering, and use ISO 12312-2 eclipse glasses only for naked-eye viewing, never at the eyepiece.
- A Barlow lens. Not included; Space.com needed one for Mars. A 2× Barlow is the usual fix.
- Dew control. A SVBONY USB dew heater strip keeps the finder and eyepieces clear on humid nights.
- A red light. A red LED flashlight lets you read star charts and swap eyepieces without losing dark adaptation.

How it compares
The cheaper StarSense Explorer LT 114AZ uses the same phone-guidance system on a smaller, lighter scope, but reviewers were less impressed with its optics and tripod. Smart telescopes such as the Seestar S50 Pro take the opposite approach: tiny optics, automatic tracking and stacked photos. Our best smart telescope for planets guide explains why a traditional reflector often wins for planetary detail.
Bottom line
The DX 130AZ shows planets and the Moon better than any small smart telescope, live and through an eyepiece, for about $500. It can’t track, stack or photograph faint nebulae. If planets are the goal, this is the better buy; if nebula photos are, choose a Seestar. Check the price on Amazon.
Accessories for the StarSense DX 130AZ
Official and compatible add-ons sold on Amazon: filters, solar filters, tripods and wedges, power banks, dew control and cases. Check the listing confirms your exact model before you buy.
- SolarCelestron EclipSmart solar filter for 127 mm and 130 mm reflectorsOfficial Celestron
ISO 12312-2 compliant full-aperture filter that turns a 130 mm reflector into a safe white-light Sun scope for sunspots. Celestron lists select 127 mm and 130 mm telescopes; measure your tube's outer diameter first.
- SolarCelestron EclipSmart universal solar filter (75–100 mm)Universal fit
Adjustable ISO 12312-2 compliant film filter for objectives with an outside diameter of 75–100 mm, such as spotting scopes and some traditional telescopes. Too big for 30–50 mm smart scopes; use the maker's own solar filter on those.
- SolarThousand Oaks black-polymer solar filter sheet, 4 × 4 inUniversal fit
DIY solar film for making a secure full-aperture filter cell for a small scope or camera lens. Only for confident DIYers: the cell must fit tightly over the front so it can't blow off. Never use a filter at the eyepiece end.
- SolarSoluna ISO 12312-2 solar eclipse glasses (2-pack)Universal fit
For looking at the Sun with your own eyes while the scope images it; never look through a telescope with them.
- FilterOptolong L-eXtreme 7 nm dual narrowband filter (2-inch)Compatible, third-party
Tight 7 nm H-alpha and OIII passbands: the go-to filter for nebulae from heavily light-polluted skies. Needs a 2-inch adapter: the S50 Pro adapter above or an M48 adapter for the Dwarf 3. Only useful on emission nebulae.
- PowerAnker 737 power bank, 24,000 mAh, 140 WUniversal fit
USB-C PD power bank big enough to run a 30–50 mm smart scope through a long winter night, when cold cuts battery life. Check your scope's manual for supported USB-C input while observing; Unistellar, Vaonis and Celestron Origin use their own batteries and chargers.
- PowerUGREEN Nexode 100 W power bank, 20,000 mAhUniversal fit
Cheaper USB-C PD bank that also tops up your phone, which runs the telescope's app all night.
- Dew controlSVBONY SV172 USB dew heater strip, 320 mmCompatible, third-party
Three-level USB heater strip for finders, eyepieces and camera lenses on humid nights. Only for traditional optics or camera lenses; most smart scopes have their own anti-dew heating, and strapping a heater over their housings can block sensors or vents.
- ObservingCelestron Night Vision red LED flashlightUniversal fit
Dimmable red light keeps your dark adaptation for finding cables, levels and the tripod at night.
