Adding some teflon plumbing tape to the threads on the focuser can help tighten up the action.
The design choice makes sense but the quality of the focuser assembly reflects the price and there is some play in the mechanism when focusing. The 1.25″ plastic rack and pinion focuser used on similar telescopes has been replaced by a plastic helical focuser with a much lower profile. When extending the OTA the trusses seem to click into place and two large thumbscrews allow the position to be locked. The biggest difference is that upper half of the OTA collapses down, making the tube only about 16″ long when not in use. The telescope is a 130mm f/5 Netwonian reflector of similar optical design to other scopes made by Synta but with a few tweaks to the tube assembly for this scope’s intended application. I haven’t had the scope slip on me in any of my mounts but the stop screw does provide peace of mind. Here it works as a stop to prevent the scope from sliding out of a loose dovetail mount. The scope has a long Vixen-style dovetail rail attached, which allows the scope to be balanced easily balanced fore and aft while in use.Īfter setting up the scope I noticed a separately bagged screw whose purpose I wasn’t sure about until I saw that it fit in the threaded hole at the top end of the dovetail.
My telescope arrived undamaged and setup required only mounting the included red dot finder to the upper end of the tube assembly. The telescope is shipped assembled in a fairly large box. The included eyepieces are of decent quality though the scope is good enough that investing in an extra eyepiece or two is worthwhile. The OneSky comes with a wooden (particle board and laminate, to be specific) table-top mount, red dot finder, 25mm and 10mm eyepieces yielding 26x and 65x respectively, and a cheshire collimation tool. My intent in purchasing the OneSky was for use as a travelscope but for now I want to focus on its suitability as a general use telescope. The OneSky telescope is made for Celestron in China and sold in the US by AWB to help fund these programs.
