    • Amazing Telescope! Amazing Telescope!
Style: AstroMaster 102AZ
Review Image by Asu Musisi
Did a lot of research on the best telescope to buy, low maintenance with excellent images. Refractor vs Reflective was the question Refractor won hands down when you put everything together to get a well-rounded scope on a budget. Also bought a filter so as to take pictures of the moon, 2X Barlow lens and a 3X. Settled with the 2X as that is perfect. I also added a zoom lens where I can go from 7-24mm. My daughter loves this thing and we're always sky watching together. The image below was taken using my iPhone 15 Pro after I adjusted the exposure perfectly. It was amazing taking this detailed picture with such a simple setup. We have also seen Jupiter and 4 of its biggest moon, Mars, Venus and Saturn. Something happens to your spirit and mind when you see them for the first time with your own eyes. It's almost like they're whispering something to you like Hey! we were here the whole time. WOW! We forget we live in space and rotate around a star (Sun). What we do is pay attention to when objects are closest to the earth to get the most out of this telescope. Worth every penny. Now I want to buy the $1400 8SE from the same company since I want something that gathers more light, yet still small and easily portable. Dobsonian Reflector equivalent is a no go. ... show more

    • Ed’s 102AZ scope
Style: AstroMaster 102AZ
Excellent beginner scope! First night saw Saturn and its rings! Optics very clear, hope to see Jupiter soon! Don’t get anything less than 4” diameter on a refractor! I may later step up to a 6-8 reflector but not yet. This scope is great! Really easy setup right out of the box, well worth it.

    • Great entry level telescope.
Style: AstroMaster 102AZ
Bought this for my daughter as a Christmas gift. She was incredibly geeked (as I was) that we could clearly see saturn and its rings....and jupiter and its storm cloud lines. If looking for a cheap way to get started...i highly recommend.

    • Perfect for Land Use
Style: AstroMaster 102AZ
I am a beginner to astronomy so my expertise lies in seeing birds deer etc. Very clear excellent focus and magnification. I did get a zoom 8x20 Celestron eyepiece. I do suggest getting a 102 mm. If the telescope can't receive lite it can't magnify it... You can always magnify it with eyepieces. Also I may the past mistake of once getting a reflecting Telescope and the upside down images when looking at birds and animals soon may me put it away. I do not like motor driven mounts, I tried them they were nothing but trouble. The tripod slips on an excellent steel tripod in seconds. I will have to get use to smoothly moving the telescope but it really is not that hard. Every thing is well made. Refractor Telescopes hardly need any maintenance and are much more sturdier than reflectors. Reflectors are cheap. I will start looking at moons and planets soon and will update ... show more

    • Great beginner scope, needs better red dot
Style: AstroMaster 102AZ
This telescope has been fantastic for me as a beginner. I have had fantastic views of many planets, clusters and deep space objects, tripod is not perfect but works well enough, might upgrade eventually. Red dot is extremely cheap and attaches very poorly. Has broken off multiple times with little contact. Right now is being held on with superglue. I am definitely going to have to upgrade this. ... show more

    • Optics are fine but mount is terrible
Style: AstroMaster 102AZ
The 102mm aperture made for clear viewing of the moon's surface but that was it. The mount is terrible with no fine adjustment. After struggling to get an object in view, I could never get the object to stay in view as the mount moved the scope away. If you have $417 to spend only to view the moon by constantly holding the scope in place with your hand on the mount handle, then go for it. I returned mine and will wait for a better product with fine movement control to come available. ... show more

    • Almost OK Telescope on an Annoying Tripod Almost OK Telescope on an Annoying Tripod
Style: AstroMaster 102AZ
Review Image by Brooklyn Trilingual
Update: I dropped a second star after trying to use the scope to look at the moon. This year Jupiter and Saturn were both visible, so I started first on them. Nine months later, Saturn is now a daytime planet and Jupiter sets in the early evening, so I set my sights on the moon. Since I also bought a set of upgraded gold-line eyepieces, I expected to see a nice sharp image. I was very disappointed. Nothing was truly sharp. I tired every trick I knew. I went up and down the magnifications of my gold-line eyepieces. I tried both of the original Celestron eyepieces. I tried a moon filter. I tried adding my 80A filter to the moon filter. I put a cut-out over the large objective lens to reduce total light and increase contrast. I cleaned my eyepieces. I took apart the telescope and cleaned the star diagonal and the objective lens/lenses (The objective uses double lenses). Nothing helped. I began to suspect my eyesight and pulled out my binoculars and found my binoculars and gave me me a nice sharp image at one-eighth the cost. I'm still leaving this telescope 3 stars because I was impressed by it's ability to capture light and see distant faint objects, including Jupiter's moons and Saturn's rings. However, the resolution and contrast were disappointing for a $300+ telescope. Original review I dropped a star due to the annoying telescope mount on the tripod. Even with the mechanisms unlocked, when I first got the telescope, the mount was very hard to rotate, both horizontally and vertically. Basically, it is so stiff that once you put enough pressure to overcome the friction, it suddenly shoots past your target. I will provide directions on how reduce this problem, but plan on buying an 8 mm hex key (or 5/16 inch hex key) and Super Lube synthetic grease. I had a beginner telescope since I was 8 or 10 years old and shared it with my kids from time to time until it fell apart somewhere in my late 30s. I'm now past 60 and wanted to be able occasionally look at the moon and planets again, without breaking the bank. I first bought a $150 80mm Hexeum telescope, but returned it a few days later, realizing that I would have to spend lots more to replace every eyepiece and and drill some holes to install a better finder scope. So, it took a big breath, and bought the Celestron 102AZ for $300. When it arrived, I pulled the large refractor scope out of the box and was impressed. The telescope is best described as advanced beginner or pre-intermediate. I put it together and adjusted the finder scope while it was still daylight. After nightfall saw Jupiter and at least 4 moons and Saturn with its rings and at least one moon. The red-spot finder was a big help in targeting the planets and the eyepieces were pretty good for inexpensive Keller lenses. I also bought a 2X and a 3X Svbony Barlow lens to make the images bigger. I was impressed by the quality of the images, even with the beginner eyepieces. Now for the tripod. I know some reviewers expect a heavier tripod, but i found it sturdy enough, especially after trying the lightweight tripod that came with the $150 Hexeum telescope that I returned. However, the telescope mount was very, very stiff for both horizontal rotation (azimuth) and vertical up and down (altitude). I tried oiling various parts with WD-40 and light oil, but that solution failed. After email correspondence with Celestron and reading about similar complaints online, here is what I found. Between the tripod legs, under the mount, there is an overtightened bolt that attaches the horizontal rotating plate to the base that attaches to the legs. Turn the mount upside-down, then use an 8mm (or 5/16 inch) hex key (same thing as an Allen wrench) to loosen the bottom bolt counter-clockwise about a quarter turn. If that's not enough, turn it a hair more. Now flip it back over and try rotating the mount horizontally. If unlocked, it should turn smoothly and freely with almost no friction. The altitude (up and down) mechanism is a little harder to fix. The altitude mechanism attaches the telescope to a horizontally split tube that rotates around two parallel black disks, one on each side of the altitude mechanism, The disks are hidden by an orange cap on one side and grey metal on the other side, but they are visible though the horizontal split (or gap) in the mechanism. You may need a bright light or flashlight to look in the gap and see the black disks. The twisting handle, called the pan handle, reduces the size of the horizontal split (gap), causing the tube to grip onto the disks. Unfortunately, even when completely loosened, there still too much friction on the disks. To reduce the friction, buy some Super Lube Multipurpose Synthetic Grease, then take a toothpick or skewer and dab some grease on the edge of the black disks, which can only be reached through the horizontal "split" or gap in the altitude tube. After you dab in some grease, loosen the pan handle lever and rotate the altitude down and up, over and back in order to spread the grease. I had to dab the grease on the edges of the gap a several times and at multiple altitudes. Although the altitude rotation is not as smooth as I would like, it is a lot better with the synthetic grease. One more detail. Unlike the Hexeum telescope, the Celestron AstroMaster 102AZ does not come with a free carry bag. A decent carry bag is not cheap but is a worthwhile purchase to protect your telescope, especially if you ever need to store the telescope, move to a new apartment, or travel with the telescope. ... show more
