To begin, the photos are shaky and blurry because I shot them by trying to stick my phone close to the eyepiece, they do not do this scope justice, it is fantastic! I had very limited experience with telescopes, but the 127 SLT has blown away my expectations. I have seen the Orion's Nebula, rings of Saturn, bands of Jupiter and the 4 Galilean moons clearly. Various star clusters and a couple galaxies. Once you understand the setup and the must have upgrades you'll be ready to go. Pros: The scope is easy to assemble. The red dot is perfectly fine for what it is and gets you close enough. The 5" lens is more than enough to see the usual objects (moon, Saturn, Jupiter, and other Solar System Bodies). The first time i found the Andromeda Galaxy i was a bit disappointed as it just looked like a yellowish smudge in the sky, cool nonetheless. Then I observed Orion's Nebula and couldn't believe how good this little scope does, granted the tripod leaves much to be desired (but there are cheap work arounds, I'll explain in the cons. It's portable if you buy the right case which is great to get out of the city light pollution or to take camping. The tracking and auto alignments are great. Always perform the 2 star alignment as the 3 star align fails 9 out of 10 times, but 2 star is very good. Once 2 star is aligned you can activate tracking and the scope keeps the object you're viewing within frame or very close over a period of time, and you can let the computer drive you to your next object. It's super useful on cold nights and to not have to constantly correct where you're looking. Cons: the mount/tripod is not great, but I've mitigated vibrations and instability by buying cheap anti vibration pads on Amazon $20 and by loading a sandbag with 10lb weight and placing it on the plate of the tripod and this makes it 100 times better. This will be something I upgrade eventually for my own purpose, but I have no problems now and have no need to upgrade after the pads and sandbag trick. The standard pieces you'll want to replace and buy better one's, these pieces are always cheap that come with the scope, but I still use the 32mm for initially locating the object I'm looking for. You'll want something around a 25-32mm, 15mm, and a 9mm , and a 2x Barlow, this is all you need and you will be able to push your scope to its limits and on good nights with low atmospheric interference push a little past them. Further, i cannot say much on battery longevity in the scope as I immediately bought a cheap $8 adapter and used an extension cord for power until I bought the celestron mobile power supply for when I take it on the go. Overall, i wouldn't have changed my mind, this purchase was perfect, the tube didn't need alignment, the motors haven't messed up on me and i have nothing negative to say about this purchase. Recommended: buy the power supply, it's a game changer. Also, get the anti vibration pads and some way to weigh the tripod down, this makes a world of difference. Upgrade your eye pieces, you don't need anything crazy expensive, and buy a case to store your tube, tripod, and accessories, it makes storage and moving it a breeze. There are other well written reviews, so take your time and review what you need before buying. As my first telescope as an adult I'd rate this 9/10 for price and the ease of use and accessories built into the computer of the mount. Next scope will be a 10" lens with a solid equatorial mount base as i have no place for a Dobsonian in my current living situation. Good luck and clear skies!

Easy to assemble and simple to align. It took a few minutes to make a solar system align. After I was able to see a Moon and make a photo shoot with smartphone. The finderscope I changed because I didn’t not like it.

Monterosa fotografaro da Milano City Life. Ottima visione anche della congiunzione Saturno-Giove al solstizio d’inverno. La correzione cromatica delle lenti non è completa.

I have use this to view the Sun (with a Bader solar filter), Moon, Jupiter, Saturn, Albireo, Andromeda, and Pleiades. You get stunning views of the moon and sunspots are very distinguishable with this scope. Saturn is pretty small, but the rings are distinct and some moons can be spotted around Saturn. I was able to faintly see the bands of Jupiter and the Galilean moons are pretty bright. You would need a bigger telescope to get more detail from the planetary objects, but the views you get in this scope still makes anyone who looks pretty amazed at what they are viewing. I love the fact this has a computerized tripod mount. This takes the frustrations away of trying to keep an object in view as well as trying to locate something in the vast night sky. The setup take some practice, but it does get easier after a few attempts. My neighbor has an 8” Nexstar SL with the StarSense Automatic Alignment Accessory and I still usually beat him to having an aligned telescope by doing it with the built in SkyAlign method. The tracking is good as long as you have fresh batteries, but I highly recommend using an external power source because the batteries get drained in a few hours. I also recommend using an app to help locate objects. I am planning on getting the WiFi modules so I can use my phone to control the telescope. The included hand controller does take some time to learn, and the menu navigation can be clunky. You can use the free Celestron SkyPortal app for control your scope if you have the WiFi module. Once you have the telescope aligned it is pretty accurate on its tracking. One night I centered Saturn and went inside to watch TV for 2 hours and I was amazed that Saturn was still in the eyepiece when I came back out! You will want to make sure you have the tripod level, fresh batteries, the correct latitude/longitude, time, and date to help ensure your tracking is accurate. This Telescope has made me excited to get out on clear nights and discover the night sky and has also helped get me into trying astrophotography. I was able to use my Olympus E-PL5 the other night piggy backed on the telescope which helped me get a decent shot of Andromeda. I took an hour of exposures it was nice to have the tracking of the telescope available so Andromeda stayed centered in my camera. I also bought a T-Adapter so I could photograph objects using the telescope as a prime lens. My sun and moon shots came out very clear using this method. The sun and moon shots attached are not cropped, and you can see almost the entire frame is consumed by the sun or moon which give a great amount of detail. I highly recommend this telescope! If you can afford a larger telescope, then get the biggest one you can afford, but even though this is only a 3 1/2" scope it can give you some great views of the night sky.
