Worked Perfectly for a 4" Telescope
My set was missing the smaller mirror. The only option is to return the larger mirror but I already have installed it. The seller reached out to me after my negative review and sent me a replacement. Both mirrors are in perfect condition and the seller was responsive so I'm giving them 5 stars.

Inexpensive yet great quality
I rebuilt an almost free goodwill reflector telescope using these mirrors. They were a perfect fit and an inexpensive way to bring a telescope back into service.

Clean finish and a good fit.
The mirrors were clean and well made. Great for when replacing the old mirrors in my 114mm Newtonian.

These are all spherical, only the smallest are suitable for telescopes
The media could not be loaded. This is an excellent but spherical 8” mirror, which isn’t specified in the listing. The 114 mirror might be usable when spherical, but anything larger is pointless as a spherical mirror. It’s pretty decent, and the focal length is spot-on, but it’s useless for a telescope.I’ve included a Ronchigram, both as a photo and a video moving the Ronchi screen through the focal point.

Great customer support
I have an older Meade 114EQ-DH4 telescope and both mirrors had gotten quite pitted and needed replacement. While the 114mm mirror was great, the provided secondary mirror actually measured 24.6mm and fell out of my holder. The people at SKYOPTIKST were good enough to send me a larger (28mm) secondary mirror as a replacement part.I'm no optics expert, but my telescope is a lot clearer and brighter with these new mirrors.
