Even after numerous times collapsing the tube, it still retains the optical alignment without any necessary adjustments. The build quality is robust and sturdy and is excellent at maintaining optical alignment.
This style of design, with a collapsing tube, is only as good as its stability. There are nylon screws on either side of the tube to lock the truss tubes into position.

To operate the scope, you push the mirror array to give the full 26 inches working focal length. The front section comprises a solid plastic ring that holds the mirror array-secondary mirror, focuser, and finder attached to a metal truss tube. One of the most notable features of this telescope is its 15-inch length. The Onesky is a 130mm ( just over 5 inches of aperture) f/5 Newtonian reflector. Once the scope is locked in place, there is a carrying handle on the side for easy transportation. The screw is there to prevent the telescope from slipping out of the dovetail mount if it was loose. There is a screw that fits in the top of the dovetail. The dovetail lets you easily balance the telescope on its altitude axis. The scope’s optical tube attaches to the mount via a Vixen-style dovetail assembly, locking in place with a hand knob. The 10mm eyepiece works exceptionally well for viewing the moon. As mentioned, the 25mm eyepiece offers a 26x magnification with a 2-degree field, making it simple to aim the red dot finder at your targets. The red dot finder requires mounting on the top end of the tube assembly. There’s not a great deal of set up necessary. Many popular telescopes have a similar configuration, but the Onesky is superior in many details, which we will get to later in this review. The Onesky itself is a short-focus, tabletop Newtonian reflector telescope with an alt-azimuth mount. The two eyepieces are high-quality optics, but the telescope is good enough quality that some more expensive eyepieces would be worth the investment. The collimation eyepiece is there because reflector telescopes require collimation-aligning your primary mirror with the center of your eyepiece. They are achromat doublet: Kellner 3-lens design with an anti-reflection coating. The two viewing eyepieces are 25mm (26x magnification) and 10mm (65x magnification).
Two of the eyepieces you’ll use to view through the telescope, and the third is there to collimate the scope. Inside the main package, you’ll find a separate smaller box with the red dot finder and three eyepieces. When you open the box, the Onesky is almost ready to go for you.
