    • Greatest birthdays present ever
I bought this for my husband's birthday. He loves all thing space. He was so excited that he assembled it in about 15 minutes and took it outside to begin exploring. The clarity of the view is phenomenal and the ability to capture photos on his phone adds another level to the experience. The telescope, fully assembled with tripod, is super lightweight and easy to use. I look forward to spending hours with him exploring the moon and stars in space. The price was reasonable and shipping was fast. All around happy with my purchase. A great first telescope. ... show more

Great value for the money and it is easy to set up. It is made of good quality and is suitable for beginners. My 12 year old and I enjoy setting it up. Love the phone accessory as well.

    • Does the job
Not bad for being on the cheaper side. It was hard to dial in the focus and isn’t super stable. Gets the interest going but definitely for beginners.

    • Great Entry Level Telescope!
Review Image by M. Aster
Review Image by M. Aster
This is a solid, low-maintenance refractor that’s perfect for a "grab-and-go" setup. For an 80mm scope, the optics are surprisingly crisp, the Moon looks great, and you can easily pick out Saturn’s rings. Since it’s a refractor, I don't have to worry about aligning mirrors, which is a huge plus for me. The tripod is very lightweight and easy to carry into the backyard, though that portability comes with a bit of "shake" when you’re focusing or if it's windy. Overall, it's a great, straightforward entry-level scope for someone who wants clear views of the solar system without a complicated setup. ... show more

    • Awesome Beginner Telescope
Review Image by Danny
I'm surprised with the quality of this telescope. It is a great beginner telescope. I was able to set it up in a few minutes without any instructions so it is self explanatory. The image is pretty clear you can see far away. Great for looking at the moon and far objects but don't expect to be able to clearly see planets or other small stars. ... show more

    • Surprisingly Awesome Telescope!
Didn’t expect much at this price, but this thing really impressed me. Super easy to set up — had it ready to go in about 10 minutes. The view of the moon was crystal clear, and I even managed to spot Jupiter! The tripod feels solid, and it’s light enough to move around the yard. Great little telescope for anyone wanting to get into stargazing without breaking the bank. ... show more

    • Very good telescope

The telescope was very easy to install and the phone adapter attaching feature was handy to keep the phone on the lens and directly point at the skies. It also comes with a small portable chair and the entire package is very light to carry around. Would highly recommend.

    • Great telescope but disappointing tripod.
The telescope itself seems quite good, but the tripod is disappointing... it doesn't hold the azimuth (no phone attached either) and I don't dare tighten it anymore for fear of breaking it.
