Powerful focal reducer in a small form factor - make sure that's what you need
A powerful focal reducer in a small factor. I purchased it to help my guiding scope focus on large objects that took too much of my field of view and did not care about aberrations that might accompany this type of optics. Good value for the money.

Still have to figure out focus distance- using with zwo120 and orion 60mm guide scope
I'm trying to find the focus point while using it with an Orion 60mm guidescope and a ZWO 120 camera & 1.25 adapter. I ordered an Orion 1.25" extension tube. Maybe that will help but I'm not sure. For $11 the lens looks OK to me. Hopefully I'll be able to use it. If not I will try it with my eye pieces.

Would not recommend! Threads and optics are bad!!!!!
The threading is horrible, the optics are even worse (it reduced the field of view of the sky as it should, but drastically reduced my eyepiece's FOV). It also doesn't thread on properly to the bottom of my 1.25 inch eyepieces, or my 1.25 inch diagonal mirror. The focul reducer lens nearly fell into the optical tube. Will be making a return right away. I've used other SVBONY products like their eyepieces and phone-telescope adapters; this is the first disappointing product that I've purchased from them.

Cheap quality but works.
The lens quality is not good, there is a lot of defraction especially towards the edge of the fov. But it still gets the job done if you're planning on just observation Photography not so much.

La calidad del producto es suficiente para observaciones rápidas. No funciona con ocultes de más de 25 mm, pues se forma una viñeta. Es útil para oculares medianos, quizás 20 mm o menos. La reducción es de 0.7 aprox no 0.5
