    5.0 out of 5 stars Great purchase!
    Reviewed in the United States on September 23, 2020
    Where to start...first, I am so happy with this telescope! We transitioned from the Celestron 80MM Star Sense Explorer to this scope. Quite a jump, I know but so glad we did. So...it was a bit heavier than expected but manageable. I had to do a lot of reading and I am still learning about the "utilities" and settings and it definitely took some time to get used to. The manual is okay but you will find more on You tube and on the Celestron website for tutorials. Putting the scope together was simple enough. The red dot finder is not great, definitely need to upgrade that if you choose not to purchase the Star Sense Auto Align. More on that later. The 25 mm lens that comes with the scope is actually really good and we pair it with the Barlow lens. The scope arrived in great condition and was packaged nicely. The tripod is decent and easy to adjust. So back to the Auto Align. the first few times we took the scope out we attempted to use the 3-star alignment....never could get it to work correctly....having said that...we live in a light polluted area near Nashville so we expected some issues. After attempting this alignment several times we decided to purchase the Star Sense Auto Align...I know it is fairly pricey but wow, so glad we did!!! The Star Sense aligned the first time and has worked great each time (read my review on that one as well, hopefully it will help if you decide to purchase it). I had never seen the Orion Nebula before and my first early morning viewing was breathtaking! Views of Saturn, the Moon, and Jupiter are fantastic...you can see the Cassini division in Saturn's rings. Images are clear and detailed. The one thing that I was unaware of when purchasing this scope and only found out after watching some You Tube videos is that you have to upgrade the firmware on the mount....the joy of being a newbie! So things we purchased for this scope that may be of use for someone purchasing it:
    1. Celestron X-Cel 12 MM lens
    2. Celestron X-Cel 3x Barlow
    3. Celestron Oxygen iii Filter
    4. Baader UHC-S Nebula Filter
    5. Celestron Solar Filter (8" for the 8 SE)
    6. Celestron Lithium Power Tank 12 V (a must have or you will be replacing batteries every 30 minutes)
    7. Colored filters but mainly Red, Violet, Blue, and a Moon filter...haven't used the other colors yet. Orion has a
    great set, although it is expensive.
    8. A carrying case- we travel a lot....Celestron has one for this tube size, otherwise use the boxes it came in- they
    work just as great!
    9. A pelican case for your eyepieces and filters....we purchased one with pullouts and made our own...or you can
    buy one from Celestron.
    10. And a must have for those living in the South or colder climates...a dew shield or heater!
    11. A red flash light or just use the red light on the Lithium Power tank.
    12. Last but not least....for newbies...there are several companion books you can purchase....The Backyard Astronomer's Guide, Night Watch, The Total Skywatcher's Manual, and National Geographic has some great books. We love locating things in the sky, then looking them up and reading about them. The books also contain great tips and suggestions from purchasing eyepieces to filters, and how to best view objects in the night sky.

    All of these items were purchased on Amazon and we bought them over time but each purchase has enhanced our viewing and really made our nights out so enjoyable.

    Pros: So many but to name a few...
    Great, clear images, mostly newbie friendly- just have to educate yourself on operating the telescope to get the most out of it, a lot of items available for purchase to upgrade your experience, and with the star sense auto align you can spend hours outside enjoying clear skies. Not to say most people cannot get the 3-star alignment, we just lost patience with it and purchased the auto align :-)

    Cons: Manual not so great...You Tube has great videos from knowledgeable enthusiasts, it seems a bit heavy but manageable for one person. My husband is always with me so portability isn't an issue but just going out alone it may be somewhat heavy.

    Overall, I am so happy with this purchase and would recommend it for anyone wanting to add a more advanced telescope to their collection. There are several tutorials available online at Celestron and via You Tube that I encourage you to view. The telescope can be a bit intimidating for those that are new to the hobby but with a little research you will be loving it! We take it out at least 3x per week (skies permitting). The most beautiful site seen was the other morning I went out at 5 am and viewed Venus...the moon, and Orion's Nebula...so clear and amazing...it was definitely a treasure trove that morning, spent about 90 minutes viewing the sky until the Sun started to come up...very peaceful! We are still learning this telescope and each thing we learn just enhances our experience. I was hesitant on this purchase at first...a lot of money to spend plus accessories but we are so glad we decided to buy it! Definitely do your research to determine which telescope is best for you and your goals but this is a great one for those just entering the hobby or graduating from a starter scope. Now if we could only afford to buy another one of these so my husband and I don't fight over viewing time!

    5.0 out of 5 stars Buy the scope, but you may want to invest in a power supply and a better finder scope
    Reviewed in the United States on May 5, 2022
    I love this scope. It deserves 5 stars, but I would knock one-half star off if I could for the following two reasons:

    1. No power supply. You have to buy 8 AA alkaline batteries to use it at all, and they don't last more than a few nights of viewing, depending on how much you move the scope around, and how long you have it powered up. At this price, Celestron should include a power supply, whether it is a wall wart or something like a lithium power pack (good units that they do sell separately), even if doing so adds another $20-80 to the sale price. The scope moves more slowly (but not terribly slow), and the hand control backlight is dimmer, when running on the internal batteries. You'll likely be back on Amazon again soon after you take delivery, looking for something better than the internal battery setup. My advice is to avoid buying a wall wart unless you have long extension cords or AC outlets very near your intended viewing spot. Instead, spend a few more dollars on a portable lithium battery supply from Celestron or a third party, and you'll have plenty of power and mobility, too. The scope has an external power socket-- the common 5.5mm by 2.1mm bayonet, and it does not need exactly 12 volts DC. It apparently tolerates 11-14.5 volts or maybe a bit more. You can also buy a Celestron cigarette lighter plug, so it should be compatible with standard automotive battery power. In my case, I bought this compact lithium pack and I'm very happy with it: https://www.amazon.com/gp/product/B07YRZYLKV/

    2. The "Star Pointer" spotting device included with this telescope is OK-ish, but as time passes, you may want to consider an optical finder with some small level of magnification and possibly crosshairs. I'm planning to do this in the near future after my credit card cools off. I'm not a big fan of the Star Pointer. Some people like it, others have said it's not aligning with the main scope for them. I spent more time fumbling with mine than I did with the rest of the scope. Some of the fumbles were my fault, though. There are a few YouTube videos that show possible solutions if you can't get your Star Pointer and your telescope to agree with each other. The idea is to add a small shim, like thin cardboard or even a US dime, under the back of the dovetail bracket. Just loosen the two screws and slip the shim under the back, then re-tighten the screws that hold the finder dovetail in place. It gives some extra tilt inward and downward towards the telescope body. If you can't center the image and it feels like you need to move the red dot down and to the left of the end of travel, you might try this.

    Celestron has made a very good, solid telescope with super optics. I'm a big fan of the hand control and its built-in ability to help you find great stuff in the sky. It's first-rate. It's especially good for novice astronomers, in my opinion, and saves a lot of time that would otherwise be spent searching for things when you're new to the hobby.

    If you don't mind some advice: PLEASE, if this is your first telescope, don't buy a bunch of extra eyepieces, filters or Barlows just yet. Enjoy the included 25mm eyepiece first. It has plenty of magnification without being too much--and too much is what a lot of newbies (myself included) end up with. If you buy eyepieces that give you greater magnification, you'll only be frustrated until you get to know your way around. If anything, you'll get a lot of use out of an eyepiece that even widens your field of view more (lower magnification), like a 32-40mm eyepiece, or even a focal reducer. I have the Celestron f6.3 focal reducer/corrector, and I couldn't be happier with it.

    As a last thought, get one of Celestron's inexpensive, but surprisingly good 7 X 50 binoculars. At 7 times magnification, they are great for viewing the constellations and helping you decide what part of the sky to point your telescope at next! I'm happy I got both. The telescope and the binoculars each add their own level of joy to the night's experience.

    Even in a suburban environment with lights all around us, I'm still blown away by how many stars I can see with the binoculars compared to my unaided eyes. And of course, the telescope just makes everything that much closer and brighter.
