Review: Great for DIY Newtonian telescopes - Perfect for a fun project telescope. I bought 3 of these sets, one for my Dad, one for my youngest son, and one for myself. We used them in 114mm Hadley telescopes that we 3D printed the majority of the parts for.

### ⭐⭐⭐⭐⭐ Great for DIY Newtonian telescopes
*by J***D on November 1, 2025*

Perfect for a fun project telescope. I bought 3 of these sets, one for my Dad, one for my youngest son, and one for myself. We used them in 114mm Hadley telescopes that we 3D printed the majority of the parts for. We have really enjoyed the views that these inexpensive mirrors have provided of the moon, and our planetary neighbors.

### ⭐⭐⭐⭐⭐ Used for a Hadley Telescope, worked very nicely.
*by G***G on March 19, 2025*

Used for a Hadley Telescope, worked very nicely. Very nicely packed and inexpensive.

### ⭐⭐⭐⭐⭐ The Real Deal - Very good sphere for 30 bucks
*by M***R on January 17, 2024*

I had a bad experience with a different amazon seller- the ronchi test showed severe zones in the sphere, some of the worst I've ever seen. This mirror is great, with only slight undercorrection and some TDE at the edge- this is time consuming to remove and largely doesn't affect the view, and can easily be masked. In some cases, like this one, it may even be beneficial to have a slight bit of TDE (but it gets complicated). Overall this is a great buy for 30 dollars. Attached is my outside ROC ronchi test of this mirror, Blue, and a perfect ronchi test, black and white. You can be confident in this purchase.
