Questions & Answers

Would you mind giving me some instructions regarding the placement of the secondary mirror in relation to the primary mirror ?

Neither the mirror set nor the instructions come with them. Many of our customers have contacted us after doing a search on you tube on "collimating the secondary mirror on a telescope," and they responded that they found the information

Would you also have a set that is similar but larger in diameter available for sale?

Those are the largest mirror sets that we have that include all the cells that we have. The 203mm mirrors we have are larger than our standard mirrors, and we do not offer them with cells

(The stuff that supports the mirrors) What kind of material is the frame?

Thanks for reaching out. We use heavyduty plastic for the main mirror cell bodies. There are several metal components in both the primary mirror and secondary mirror cells as well, such as screws, primary mirror plates, collimation adjustment knobs, etc. Please keep me updated.

Selected User Reviews For Telescope Mirror Set - 80mm Primary & 31mm X 22mm Secondary with Cells

This is an excellent hobby piece at a great value

5/5

Not only are the optics matched, but the coatings are improved as well, giving you an excellent value. A spherical surface of F/10 on an 80 mm size is minimally distorted. Take advantage of the opportunity to purchase this one. This is the perfect gift for ATM fans and milky way enthusiasts.
