Nice product

Easy to assemble and intuitive to work with. Good purchase for a gift!

Perfect for a starter scope

This telescope was very easy to assemble, I barely needed the instructions, though the instructions were clear and precise. I've only taken it outside twice because of weather. But let me tell you, this thing is great!! I use a star viewer app to help line things up. I haven't used the phone mount for pictures yet. I bought this for myself for my birthday and was over the moon (pun intended) when it arrived. To the point that I put it together in my parents kitchen at 11:30pm. Assembly took approx 20 minutes. If you're just getting into star viewing I definitely suggest this scope. If you're limited on space but want a decent product, this is your 'guy'.

An amazing telescope for novice stargazers

After my 12-year-old son received a completely useless "toy" telescope for a birthday present, we decided to research and find a replacement that he could actually use. He is a novice with a huge interest in stargazing, so we wanted to find something that wasn't too expensive, but that would actually allow him to view objects in space. After reading countless 5-star reviews on the Gsyker Telescope, we gave it a shot, and we are so happy. Assembly was extremely simple, and within 30 minutes, we were outside looking at the moon. The build quality is very good - it has weight behind it and is stable when viewing. If I had one minor gripe, it would be that there is no fine control on the tripod, so when using the max magnification tubes, it can be a little tough to center on whatever you are trying to view, but because the tripod is so stable, this is not completely necessary. Overall, we are very happy with this telescope and will get many years of use out of it - the only thing holding us back right now is our terrible winter weather.

I would highly recommend this telescope to anyone looking to get into stargazing who doesn't have a huge budget - you won't be disappointed!

Good start at staring st space, but sketchy position locking can make it frustrating.

I got some great pics of the moon with this. Anything past that gets a bit difficult. Aligning the spotter scope is a bit annoying, it also has some “spring” on the mount making need adjustment fairly often.

The telescope is pretty good but keep it away from dust/humidity. If it is a cool night, it can start accumulating quickly on the lenses, reasonable enough to clean, but even being sealed some of the inner lenses got “spotty”.

The biggest setback to regular usage is the “drop” after locking position. Its a small amount, but when aligning at something that far away, its more then enough to force you to gamble on the drop positioning. You can quickly lose a target you just locked on due to the drop and readjusting. It is easy enough to keep readjusting on something close like the moon, but farther or smaller targets can be very discouraging.

Great for my 7 year old!

I Purchased for my 7 year old's first telescope. This is a good balance between entry-level cost-effectiveness and legit quality lensing. I found it relatively simple to assemble right out of the box.

It's super great for sighting the moon and Mars. Smaller stars are just white dots. You can see excellent detail in the moon with this telescope.
