Excellent scope for a beginner
By Richard M Ferko on Reviewed in the United States on November 3, 2024
I've always been interested in astronomy. Got a decent little refractor scope when I was in elementary school, and received a little 3" SCT for a graduation gift because Halley’s Comet was due back the following year (yes, I'm old). Life happened and I paused that hobby, but always wanted to go back. Finally took the plunge and looked through many forum posts and pages of reviews until I settled on getting the Celestron StarSense Explorer DX 130AZ as my return ticket to backyard astronomy. I am really glad I did. I live in a major city with lots of light pollution. There's a street light right behind my house, my neighbors (all our houses are fairly close together) have high wattage security lights, etc. So I wasn't expecting much. Figured I would need to plan some nights out at places away from the city. But of course when the scope arrived I wanted to try it out right away. Putting it together took about 30 minutes, but I was purposely going slow so that I was sure I got everything right. The only hiccup was when I was "attaching" the accessory tray to the tripod. The instructions make it seem like you're screwing it into the cross braces of the tripod, but there are no threads or nuts in the holes. So you're just cranking the screws all the way into the tray so that when you position the tray over the cross braces, the screws go down through those holes keeping the cross braces from closing on you unexpectedly. I'm guessing it's designed that way so you don't have to unscrew everything to get the tripod closed. Just lift out the tray. Getting the red dot finder sighted in was easy. I did it during the day as noted in the setup guide. The ease with which I was able to find things later that night let me know it was working perfectly. My first surprise was how much I could see even with all of the light pollution. Naked eye viewing around here I maybe see 50 or so stars. The planets from Mercury to Saturn are usually pretty visible. Since Saturn was sitting right there in the southern sky that night, I started with it. I had never seen the rings of Saturn through the dinky little scopes I'd had in the past. That night I saw them clearly for the first time (too bad they're nearly edge-on now). It was awesome. From there I was like a kid in a candy store. Jupiter with the just-past-full moon right above it came up, so I spent a lot of time on them. And then the Pleiades. Once I put the red dot finder on something, it was in the eyepiece and the slow motion controls made it easy to keep it there. That was about the time I remembered the other major feature of this scope - the Starsense Explorer app. I opened the cover over the mirrored portion of the phone holder. Started the app and placed the phone in the holder, then followed the quick instructions on getting it setup. I pointed the scope at Vega which was shining brightly in the west, told the app that was the star I was looking at by zooming in on it on the phone, hit done and in 5 seconds the app told me it knew where it was. Testing it out, I told it to take me back to Saturn, and in 10 seconds I was seeing the ringed planet again. I went to go back to Vega and chanced across something that looked interesting. In the low power 25mm eyepiece it was a bright start that looked like it had a partner. Popped in the 10mm eyepiece and used the slow motion controls to get back on it, and saw it was a very pretty double star. One was bright orange-gold while the other was a cooler blue. I checked the app and it told me I was looking at Albireo/Beta Cygni. I hadn't ever heard of it. Clicked on the info and there was even an audio explanation of the stars. Awesome. Figuring out I could just slew the scope around and then check the app for what was interesting in that section of sky, I was off to the races again. I forget how many things I looked at - more double stars (I definitely recall looking at the double double/epsilon lyrae), Rigel, Betelgeuse, Bellatrix, and could even just make out a blurry cloud that was Andromeda. All from my very light polluted front and back yards. I did buy a phone mount to go with it, but hadn't even looked at that mount yet. I didn't get the scope for any kind of astrophotography, but figured I might want to take a few pix here and there. Now I wanted to show my wife and kids what I got to see, so I set about connecting it up. It's really difficult to get it lined up correctly with the eyepiece, but I got there in the end. I attached a couple of the better photos, but they're all terribly over-exposed and a little blurry as it was hard to get the phone camera to focus. Just know that this was done basically out-of-the-box after just a couple hours of use. No special camera or photo app or good viewing conditions. I was having a blast. The summary: This scope is perfect for a beginner (or a not-quite beginner that hasn't done any backyard astronomy for a looooong time). The price was less than I was expecting when I started looking, but it doesn't feel cheap. And I didn't want to break the bank in case this wasn't as fun as I recalled (it's even more fun/exciting/satisfying than I remembered). And the performance to me is exceptional. I've had it for two weeks now and I've been out every night that the weather has let me. I've gotten a couple upgraded eyepieces and a 2X barlow, and it's only gotten more fun. The app is extremely useful letting me get on what I want to look at in seconds, or as a source of info when I just want to start randomly touring the sky. And newtonians are a simple design, after looking over the hardware I don't think I'll have any problems when any maintenance (like collimation) is needed.

An OK telescope, however...
By BlueTangHouse on Reviewed in the United States on November 1, 2024
First off, let me say that although my review is overall negative, consumers should appreciate that I believe that the DX130AZ is a good value as a beginner telescope and the few critical comments that I will make about the instrument should be taken as informational. Because I live in the British Virgin Islands, and maintain a PO box in the nearby US Virgin Islands, I often shop on Amazon which will deliver to the PO box. I have a third party service collect my mail and deliver to me here in the BVI. I purchased the DX130AZ which Amazon would not ship to my PO box, in all probability because of the large box in which it is shipped. I had it delivered to a freight forwarder in Miami, who then air shipped to me for just over for $241.50. When it arrived and I opened the box, I found that the primary mirror was dislodged from its mount in the optical tube. Being adrift inside the tube, it caused further damage to the secondary mirror, chipped and scratched. When I removed the mount I observed that the 6 screws securing the mirror were quite slack indicating that they were not capable of keeping the mirror secure. As this damage was unlikely due to the handling during shipping I called Celestron to report the problem under warranty, hoping to get replacement mirrors sent to me. However their warranty policy for products purchased on Amazon is to seek relief from Amazon first. I called Amazon. The return policy is admirable of course in that they accept returns without question and will ship me a replacement for the whole product including the scope, tripod and accessories. This works for 99.99% of the customers. In my case however it will cost me the round trip for the 3rd party shipper, getting the damaged unit back, and a replacement off to me, probably another $400 if I am successful in avoiding payment of the customs duty twice. I appealed to Celestron to simply ship me replacement mirrors and I would install myself and collimate without any difficulty. Or if not, then credit me with a replacement mirror set that I found on Amazon for $128. I would have been happy with this compromise, but it was not accepted. Then they offered to sell me a whole new optical tube, but subsequently have told me that the part is not available. Meanwhile it makes no economic sense for me to ship the entire order back, for two small parts that will fit in a small shoebox for shipping. So I ordered the replacement mirror set on my own and hope to receive shortly. I did manage to reinstall and collimate the damaged mirrors in the meantime and the scope and is functional for now. I can say in using the telescope, the most annoying aspect is the mount. It is designed to accept the phone mount for use with the starfinder app, but the neck is plastic and flexible to the extent that minor adjustments and exposure to light winds cause considerable vibration frustrating ones attempts to view objects in a stable manner. But at this price point it is not a major complaint, and minimizing the problem is part of the learning process. You will also be limited to altitude to roughly 65 to 70 degrees due to the limited clearance of the optical tube with the tripod. Makes viewing objects directly overhead difficult. Small matters but something to consider. In conclusion, I think Celestron could do better with warranty considerations for customers who clearly want resolution, but don't fit the "one size fits all" claims policy. I suspect other telescope manufacturers may be more customer service friendly, able to do the right thing when necessary. Meanwhile I could not recommend purchasing a Celestron product because of this experience.
