Celestron Cometron 114AZ has an excellent optical tube attached to a poorly made plastic mount. The result is not great, but it is quite pleasing considering the low-price tag of the Cometron 114AZ.
Celestron AstroMaster 76EQ is much better than the other AstroMaster’s, but we still don’t recommend it. The plastic mount is a frustration. While the optics are not bad, there are better choices for the same price.
