I’d l Iike to start by saying that I love your channel! I’m a little late getting into the world of astronomy.. as I just turned 54 years of age last month. I had been researching scopes, looking for “the best” overall instrument for my needs. This review helped me make up my mind.. I found a brand new Omni 102 for just under $300USD.. and I ordered a copy of your book as well!! Thanks for everything you do.. I’ll be following you, looking for advice and pointers as I begin the journey into this hobby.

Thank you so much for this video!! My husband and I just got this telescope for Christmas and we’re so excited to try it out but a bit intimidated. This video made me feel more confident, and seeing some samples of what we could see using it has made me even more excited to try it out!

Awesome review thanks to your great review and your obvious in depth knowledge I felt 110% comfortable purchasing this at Costco yesterday. This is my first telescope and look forward to more videos.

[@tridoshic1688]

This telescope actually came with an allen wrench that's actually in the mount arm

I’ll admit it took me 10mins too long to locate it. Very nice storage space for it, but terrible instructions provided on where to find it. I had a good chuckle all in all.

Great review! Yes, I hope Mr. Scott Roberts listens, lol. He is a good man, with his finger on the pulse of the astronomy community. Also just a sidenote, a couple years ago I was looking for a beginner telescope. After much research, I settled on the HWB1 sky 130. It’s a great little scope, that I continue to use to this day! Cost is US$199, and I believe is manufactured and shipped through Celestron. Keep the videos coming, great job!

[@LearnToStargaze]

Thanks for the feedback! Yes, I hope I can talk Scott or someone into bringing back a four inch refractor with slow motion controls at a reasonable price.

Excellent review and I cannot agree with you more. I've owned many vintage sears telescopes 2 and 3 inch from the 60s and 70s. I also own a 12 inch Z12 Zhumell Reflector. I bought the Omni AZ 102 mm refractor on a whim at COSCO and I'm impressed with its performance. Last night I took it out on a 16 degree F night and enjoyed views of Sirius, RIgel and the Orion Nebula. You cannot beat this telescope for price, convenience, and performance. It's a great grab and go telescope and easy to learn and use for beginners. Thanks for the video.

Supposed to be clear this weekend, and Comet will be at Perigee! Around Feb 1st! Wishing everyone clear skies for this event! This scope gives great views, and will definitely be a keeper! Outstanding for the price and quality!

Just got this scope, really cool. Saw Jupiter and moons last night but still small with 10mm eyepiece. If I wanted a little larger more detailed view of planets would you recc buying the separate 5mm eyepiece or 2-3X Barlow or both? Kids most fascinated by planets right now, so trying to maximize planet appearance. What additional eyepiece or pieces would you recc, preferably just one for saving $.

[@LearnToStargaze]

A quality eyepiece like the Celestron X-Cel 5mm would perform better than Barlow, but a barlow would be cheaper.

Yay! I got this from Costco in Dallas for $169. Quick question. What is that eye piece you are using with this telescope at 9:16 mark. what other eye pieces can we use with this telescope to increase the magnification. i would like to see a bit more detail of saturn. Thanks for your review. it was great.

Hi! This is a 26mm Plossl with a 2x Barlow. This is my favorite combination. It’s not super high magnification (I’m not really a fan of magnification) but it provides a great view.

[@Cgconst1]

John, great review! These Alt-Az mounts have a small allen key in a hole that’s near the base of the mount arm just above the azimuth slip clutch. The key is for installing and tightening the the slow motion control rods as needed. I agree that this is good beginner rig. I recommend the Celestron StarSense telescopes with slow motion controls for under $500 U.S. for serious beginners who can afford it. Love your books!!!

[@cityofbrologna]

Thanks for the review! I was wondering if there is any significant difference in the focuser build / quality between the Omni 102AZ vs. the Starsense Explorer DX 102AZ that merits stepping up to the more expensive Starsense model? Other than that they look pretty much the same and having the phone app isn’t super important for me and seems like a good way to save $100.

[@LearnToStargaze]

I think they’re the same. The app really does a good job telling you which way to push the telescope, I’ve found it to be worth it.

[@luisafernandaparramontoya3864]

Hey there, Pretty awesome video, thanks for the review. I wonder if you got any specific recommendations of what Barlow to get for this telescope.

Hi. Im a beginner and new to your channel. Ive just purchased a Celestron Starsense 102dx. The telescope looks almost identical to the one you have purchased so glad you think its good for a beginner and impressed by what I should be able to see. Hopefully here in the UK, the clouds will clear soon and I can finally get out and use it.

[@shinyy187]

I just bought the same one just a couple weeks ago! I’ve only used it in a light-polluted town so far and I’ve seen Jupiter with four of its moons, Saturn, a double star, a fuzzy Orion nebula, and a very small hazy smudge as the Andromeda galaxy. I think that’s good for not being in dark skies. The Starsense 102 is my first telescope so I’m also not experienced at all. I can’t wait to get out in some dark skies. Let me know your thoughts on it once you get some viewing time with it

[@debraskeaton]

Thanks for this review. I bought this telescope in November 2022, but I saw it during the Christmas holidays in November-December 2023. I'd advise checking Costco again during the Holiday season this year--they sometimes carry items like this seasonally. I just unboxed mine today (April 6 2024), and I don't see a red dot through Finderscope. I changed the battery but I still didn't see a red dot anywhere. Am I missing something? Finally, I'm a real "telescope newbie," so some things that might be "given" to others might not be obvious to me.

[@LearnToStargaze]

Might worth upgrading to a better red dot finder. Some of the ones that come with the scopes can be pretty unreliable.

[@debraskeaton]

@@LearnToStargaze Good suggestion. It worked later on--after I'd already sent the comment above--but I may still upgrade. I suspect the wires weren't connecting to the battery and that moving the adjustment knobs made them work.

[@a3j2leslie]

You will find the Allen key for the slow adjustment knobs slid into the mount. It is item 10 on your parts list. Look just in front of the left/right slow motion knob at the base of the mount arm in the tripod head.

[@schutztruppe]

is there a better tripod of this kind for this telescope? Like for example, I know there are different EQ tripods out there. This model is very nice in my opinion but a bit too light.

[@LearnToStargaze]

Sure, you could use this on an AZ-GTi, an Twilight I mount, a Celestron AVX, or an explore scientific iEXOS-100, anything with a vixen dovetail and enough capacity. They said, this is not an astrophotography scope, so I personally would not put it on an EQ mount (with the exception of what I did in this video).

[@MylesBabik]

Good morning. Than you for your review of the Celestron Omni XLT AZ 102. I also warched your review of the National Geographic 102mm. Both are in the same price range and appear similar. Based on your experience, which one do you think would be better? I would be purchasing a 7mm Celestron lens as you suggested in one of your videos. Thanks

[@LearnToStargaze]

Hard to say which one is better! They have the same primary lens. The mount on the Nat Geo is a bit sturdier, but the focuser is more adaptable on the Omni.

[@MylesBabik]

@@LearnToStargaze Hi John. Thank you for your quick reply. As I am only looking to use the telescope for the moon, Saturn and Jupiter for the most part, perhaps it is best to wait until both telescopes go on sale. The Nat. Geo. one is at Costco for $279 and the Celestron on Amazon for just under $300 but I noticed from your post that they have been on sale before. May I please ask another question? Whichever one I get, I was planning on buying a Celestron x-cel LX 7mm lens piece and an x-cell LX 2x barlow. With the barlow I am hoping to see the moon creators that much closer along with the red dot of Jupiter. Would you say the barlow would be helpful or would the objects lose some of their clarity? The barlow typically cost $160 so if it's not going to add much to the view, I would probably leave the barlow and just use the 7mm or maybe buy a 5mm instead? With the 7mm and barlow combined, that should take me to 188 times and I understand the max magnification for both telescopes is at arround 200. Thanks! Myles

[@LindaC-7533]

very helpful, but the red dot finder is confusing. does it turn 'on' and 'off'? I see a small white dot and it clicks, when I turn the little knob, but I can't tell the difference it might be making. otherwise -- fabulous, down and dirty, primer on this telescope ! can you by the 2x Barlows anywhere (e.g. Amazon) -- and does that extend the length of the eyepiece as in the video - so that it's a little higher when looking through it?

[@LearnToStargaze]

The red dot finder produces a very bright red dot, if you don’t see it, either the battery is dead, or the little plastic battery protector is still in place. The on off knob also serves as a brightness knob, it’s best to turn down the brightness a bit. Yes, the amazon sybony Barlows seem to work fine.

[@hvodinh]

Got one from Costco yesterday for $159. Last night, for first light, I saw Jupiter and the 4 moons. Very sharp, and I can make out the equatorial bands using the 10mm eyepiece. Makes me want to get a good 2x or 3x barlow. I'm wondering if a 3x barlow would be too much, even though with 3x you would still be under the 200x magnification.

[@LearnToStargaze]

That would probably work. A high quality eyepiece like the 5mm X-Cel (by celestron) would also go a long way to improving the view. You can also add a blue filter for extra detail on the surface of Jupiter.

[@adrianagflores5587]

[@ankurvis]

Hello John - I wanted to thank you for what you do. It was for your video that I pulled the trigger yesterday on this telescope, which I had seen in local Costco about 3-4 days ago. I am a beginner and was a little skeptical at first to buy a budget refractor, since my initial research had driven me towards a Reflector for this price range. However, I'm glad I found your video and I'm very pleased with my purchase. I was able to get pleasing views of Jupiter and Saturn on the first night (with the included eyepieces - hoping to have even better experience once the upgraded eyepiece arrives). The Mars looked very small, and perhaps Pleiades would require a broader field of view. I should be able to look at Moon tonight, once the filter arrives. Hoping to get your book soon to have a shot at the Messier objects. Thank you, again!

Yes! The mount is generic. I often use it with my solar scope.

[@JSATI]

I originally planned to pick this scope up for my kids. Checked online and in store at Costco earlier this year. I was unable to find it. I ended up settling for the Orion Starblast 4.5 for the kids.

Love this one! Super helpful for my cheap telescope search. This one would be perfect and you confirmed my thoughts. Thanks!

[@bdib]

Great review. Thanks for posting. I purchased 2x barlow lens to go with this telescope. I have read that putting the barlow lens between a reflector telescope and the diagonal increases the barlow power by 50%. Thus a 2x barlow lens between the telescope and the diagonal would provide 3x increase in magnification. Would this work for the Celeste Omnni AZ 102?

[@LearnToStargaze]

Not sure I follow your math. But yes, you could use a barlow (or simply a high powered eyepiece to help with the view of Jupiter, Saturn and the Moon (I wouldn’t use the Barlow for anything else). You can “zoom in” but the resolution stays the same.

[@bdib]

@@LearnToStargaze Thanks for responding so quickly! My question was concerning if you get more/less magnification depending on "where" you place the barlow lens. I typically put my barlow lens between the eye piece and the 90 degree diagonal. That is how I have seen you do it in your videos. However, some videos/articles by others suggest putting the barlow lens between the telescope tube and the 90 degree diagonal to get 50% more magnification. I tried putting it there but can't seem to focus the image. I didn't know if I was doing something wrong, if the Omni AZ 102 can't do that, or if the videos/articles by others were incorrect.

[@LearnToStargaze]

​@@bdib It depends on the telescope design, particularly. the position of the focal point, and the range of the focuser. Sometimes the barlow will only work between the diagonal and the telescope, and sometimes it will only work between the eyepiece and the diagonal. A 2x barlow should double the telescope's focal length, regardless of where you place it.

Your review of the Omni AZ 102 I watched a couple of times then out to Costco in Stoney Creek (Hamilton) and bought one. There are 8 to 10 still on the floor. Put together with no problems and located the allen wrench. Now comes the alignment. In your review you suggest a chimney at a distance. What is the distance and what would be optimal distance to complete the alignment process? If I do alignment outside in minus teen temperatures will this be acceptable? Thank you.

[@LearnToStargaze]

Hi! Congrats on the new telescope! A hundred feet or so should be enough to achieve focus and align the finder to the telescope. Temperature does not affect this process. You’ll need to refocus the telescope every time you set it up and every time you switch eyepieces. Good luck with the scope!

[@johnrobison1413]

I bought this at Costco here in the US for $200. My impressions about the scope has been a mixed bag, some good, some not so good. Item 1, the alt/az mount. Mine came locked up tight in altitude. Trying to contact Celestron for technical advice was impossible, left on hold for over one hour and then dropped and finally the ‘leave a call back phone number’ feature of their automated call center instead dropped my call. They did finally respond to a email. Adjusting the center nut on the fork did loosen the altitude but getting it set to just the right tension has been frustrating to say the least. The slow motion in altitude simply doesn’t work, no manner what adjustments I make on that nut. Item #2, the red dot finder is so mis-aligned that even with adjustments at full limits it isn’t possible to get it right. Celestron wants me to jump through so many complicated hoops for warranty service that their ‘warranty’ is essentially worthless! You are on your own. But, that said, I feel the scope was cheap enough that, with some work, I can get it operational. Oh yes, item #3, the attached dovetail is too short to adjust for balance if you plan to use the smart phone adapter. Sorry for the rant, but, well that is what my personal experience was.

[@saintnificent5532]

What is a decent scope and motorized mount to see Rings of Saturn with?

[@LearnToStargaze]

For a motorized mount, that depends on your budget. For $500 AZ-GTe with 102mm telescope, for $1000 Celestron Nexstar 6Se, for $2000 Celestron Evolution 8. Hope this helps!

@@LearnToStargaze Thanks & Merry Christmas! Yeah, I've been messing around with a cheap $200 refractor scope, I put a $100 barlow in it and it didn't work.

Also availability is a little tough right now. Again, Thanks!

I'm really looking hard at the Celestron NexStar 8SE. I know in this new world we are now living in I will have to pay a premium to get one. It scares me a little bit on getting it aligned, I realize patients and time are key. I just hope at first for the cost I am satisfied with just tracking and looking threw the lens before having to buy a lot of accessories. I do realize when I do purchase the telescope I will also have to purchase a power supply.

[@LearnToStargaze]

@@saintnificent5532 the 8se is a great starter scope. I find these scopes quite easy to align. Here is a video where we walk though the steps. kzbin.info/www/bejne/opqbc598d9Bsh8U

My Az 120 came with 10 and 20 mm lenses. My question is can it handle a 2x Barlow lens and whats the max magnification of different lenses for it? Kids love it!

[@LearnToStargaze]

The calculations are in the video, but remember you generally want the least amount of magnification. Increasing magnification often decreases image quality and makes a telescope much harder to use. A 25mm plossel eyepiece is generally all you need for deep sky objects. Add a 2x Barlow for planets and the Moon.

[@lornehiemstra1823]

I removed the Diagonal on this scope to see if the image would be clearer as a sort of quality test of the Diagonal. So, with a straight through configuration with just a Celestron Omni 2x barlow and a Celestron Omni Plossl 32mm eyepiece I can't seem to get anything to come into focus. Is it because the the Optical length is not long enough with the diagonal removed? I tried other eyepieces as well, 12mm, 10mm and 20mm. I did turn the focus knob all the way in each direction.

[@LearnToStargaze]

If you remove the diagonal you need spacers to make up the difference.

I have a question I saw an Omni XLT 120mm telescope for $299 is it worth getting or should I stick to Omni AZ 102

[@LearnToStargaze]

As long as you’re willing to accept the challenge of leaning how to use the equatorial mount on the 120, that would be a good option. I haven’t used that particular mount, so I can’t speak to how usable it is.

[@xxcrankxx5249]

Hi thank you for this review I did end up going for the more expensive option the Omni xlt 102 just to get the most out of my purchase

Great video, walked by this model in Costco today and Googled reveiws. I purchased this because of this video!! Alao in Alaska so saving a ton on shipping regardless, only 200$ USD.

Awesome! I need to come up with a reward program for folks who bought this telescope and see all the items in 110 Things To See with a Telescope.

[@hondaxl250k0]

I have a few of them “ hobby killer” scopes. With some simple upgrades. They are not bad for kids or the beginner astrophotographer .. throw out the stock tripod and go to good will and find a ok camera tripod. Huge difference.. then get some good eyepieces . And a cellphone camera. Even with a 50x 400 scope using 965 adapted to 1.25 I can get the Orion Nebula.. I’ve got pictures of andromeda using my great grandfathers 1950s Lafayette 60x800 refractor.. the scope is not the killer. It’s the mounts and eyepieces.

[@yeshumin2186]

Help, could you tell me how to shot as clear as your does, my phone can’t focus on the image I observed.

[@LearnToStargaze]

Try an app like Nightcap to give you better camera control.

[@gregkisinger9142]

Hi John, I just purchased this telescope at Costco and I'd appreciate some advice on what else to buy, especially since Celestron has free shipping on their accessories. I live on a lake so viewing wildlife will be fun and I'd like to view the moon and other possible space objects too. You mentioned a "2X Barlow", but is there anything else I should consider? Oh, and I'll buy your "110 Things To See...." book.

[@LearnToStargaze]

Hi! Best to get proficient using what comes with the scope, eventually the hobby will have you wanting for better eyepieces and larger apertures.

[@kkachado]

Thank you - bought one before I saw your video. I wanted to get a cheap telescope that had the ability to send pictures to my phone - so that is why I bought it. I wish that part of it was a little better and that you had more on that in the video. However, based on your video I am going to keep the telescope. I was thinking of returning it.

[@LearnToStargaze]

The best iPhone images through telescopes are with SCT or Mak telescopes using the stacking technique. Note that this is only for the Moon and Planets.

[@raybbj]

Hi John. Video topic idea for you. I own the Omni AZ 102 also and I'm very confused on 1.25" vs. 2" options. It would be great if you could do a video on 1.25" vs. 2". Advantages and disadvantages. Since I own the Omni AZ 102, I'm trying to figure out if I should upgrade to 2" since the Omni can accept it, but I can't figure out the advantages and disadvantages and whether or not I should upgrade. Thanks!

[@LearnToStargaze]

That’s really just a question of budget, and personal preference. I’m finishing up a premium eyepiece video, and all the eyepieces are 1.25. Some, like the Hyperion series, fit both sizes. If there is a 2 inch eyepiece you allready really love, then it’s worth an upgrade. Otherwise, might be better to just get a premium eyepiece like the Baader Hyperion 24mm.

[@kle2217]

Which is better this Celestron 102mm telescope or the Orion StarBlast 102mm altazimuth? Both are good for daytime / terrestrial viewing? Not sure if the Orion has an eyepiece to correct the mirrored image when viewing.

[@LearnToStargaze]

If I’m not mistaken it looks like they both come with a prism diagonal to correct for mirror reversal. I haven’t used the Orion 102, but based on several factors, it looks like the Omni 102 is better: longer focal length (less chromatic aberration), slow motion controls, two inch focusing assembly…

[@kle2217]

@@LearnToStargaze Thanks. The Omni is currently a bit more expensive too. Perhaps, that’s why.

Great Review! I bought this as a beginner telescope back in 11/2020 at Costco and you are right It was gone for a long time. I just exchanged the one I originally got because I stripped one of the screws and getting anything from Celestron is almost impossible right now. I had no problem buying it again today. This telescope really got me into the astrology and astrophotography. I now some better telescope but still use this one a lot. I’m pretty impressed with how you set it up on the equatorial mount. What Field flattener did you use? I have a SVbony 305 Pro camera and want to see what kind of images can get. Thanks for the review.

Hi! Thanks for the great comment! I used a Lightwave 0.8x focal reducer. Cheers!

Nope, just that is 1.25 inches.

[@gregkuper1387]

Thank you so much for posting this video! I have been looking so long to get a telescope that our daughters (6 and 2) could enjoy and this is exactly the right fit, but from a features and budget standpoint. I went to Costco this morning and found it for $199. It was not online-in store only. I am amazed by how solid this build is, from the metal optical tube to the mount itself. We have already spent some quality family time outside enjoying incredible views of the moon and it’s only dusk! Anyhow, thank you again for this great video. Also, I must say that I really appreciated the fact that you acknowledged that, while binoculars are great, sometimes people just want to buy a telescope. PS. Just ordered a copy of “50 Things to See with a Telescope-Kids.” Looking forward to seeing what’s up there!

Two inch mirror diagonal (dielectric is for landscapes) and a two inch, 26mm, wide field Svbony is a good choose.

May just need some WD40. The tension is this that you can move it by hand, or by the knobs. Sometimes I guess it’s a bit too tight or too loose.
