The plastic casing is appropriate however we do not suppose it might survive a considerable knock or a soaking from a passing bathe because the seals aren’t nice, in contrast to a number of the hardier, fully-sealed telescopes out there. Somewhat manipulation of the one fork arm base and you’ll nearly peer into the motor housing, viewing wires and extra. Whereas astronomers do not have a tendency to go out in a rain storm to view the celebs, the odd passing bathe does come from nowhere generally so these eager to seize this telescope will wish to cowl it earlier than it begins raining.

The adjustable tripod is fairly flimsy, though the equipment tray which holds the eyepieces and some other miscellaneous equipment is kind of helpful to stabilize the tripod legs.

The finderscope could be very useful in aiding the alignment and site of stars. As customary with crimson dot finderscopes, its vivid crimson illumination will be dimmed by way of the controlling knob on the facet to go well with no matter observing scenario you are in, whether or not it is simply after nightfall in a metropolis or a totally darkish night time sky reserve in the midst of nowhere.

You might even see Uranus and Neptune, too, in the correct circumstances. Different nebulae deep sky objects are seen in darkish skies, akin to these present in our greatest areas for astrophotography and stargazing information. The perimeters are somewhat tender, however we might solely anticipate edge-to-edge sharpness from way more costly scopes.

Extra equipment that comes with the telescope

25 mm and 10 mm eyepieces

Smartphone adapter constructed into lens cap

Adjustable tripod with accent tray

It is fast and simple to sync with the SkyPortal app, which will be arrange on any good gadget with Apple App Retailer or Google Play. The telescope has built-in Wi-Fi, and regardless of some earlier reviews we had learn earlier than testing, it appeared secure and dependable when paired with our Android gadget (Samsung S20 FE (opens in new tab)). The SkyPortal app options round 100k celestial objects to which you can also make your motorized go-to telescope mechanically slew. It slews at an inexpensive price and isn’t as frustratingly gradual as some will be. It is fairly quiet too.

  • Dependable built-in Wi-Fi
  • Quiet operation
  • Massive database of celestial objects on SkyPortal

The Celestron Astro Fi 102 comes with an built-in smartphone holder within the type of some easy elastic straps constructed into the lens cap. It appears somewhat pointless, but it surely is perhaps a useful gizmo for individuals who put their telephone down between makes use of and are susceptible to forgetting the place they’ve left it.

One slight oversight we discovered is the construct high quality of the battery pack, which we plugged right into a 12V DC port. The ability cable can change into twisted across the mount when the scope is slewing and the copper cables are simply pulled out of the fundamental crimped connections. Extra superior fashions have overcome this downside by having a strong jack port, exterior inputs and battery financial institution constructed right into a stationary part of the mount which stops cables from being over-stretched or twisted. That or a extra strong connection, maybe sealed or supported by heat-shrink plastic would assist keep away from this downside.

We also needs to point out that after you’ve got completed utilizing the finderscope, flip it off to protect energy. It is fiddly to vary the battery, so it is best to must do it as little as potential.

Since you’re primarily paying for the digital motor on the AstroFi 102, you’d maybe do properly to avoid wasting money and contemplate the cheaper push-to Celestron StarSense Explorer DX 102AZ, which we reviewed final yr. You continue to have entry to the app, which can assist you discover objects within the night time sky, but it surely will not transfer electronically for you. Some traditionalists may even favor the extra tactile method.

The Celestron Encourage 100AZ refractor, which we reviewed lately can also be a superb price range, newbie telescope and is suited to those that wish to dabble in some smartphone astrophotography as properly. It comes with a way more strong tripod and is way more fairly priced as properly — nice for people who have a tighter price range.
