Description
Observatory-grade equatorial support accompanies the Celestron SC 279/2800 CGX-L 1100 GoTo, an 11-inch Schmidt-Cassegrain telescope with a 2800 mm focal length and listed f/10 optical ratio. Its CGX-L German equatorial mount provides heavy-duty tracking, dual dovetail support, high instrument capacity, NexStar+ control, CPWI compatibility, StarBright XLT optical performance, 40 mm eyepiece, 9×50 finder, stainless steel tripod, two counterweights, and DC power cable.
The aluminum optical tube uses internal primary focusing and Fastar and HyperStar compatibility, while the 279.4 mm aperture supports the listed lunar, planetary, deep-sky, and astrophotography applications. The CGX-L configuration is intended for larger accessory and instrument chains, so correct balance, polar alignment, power management, thermal preparation, and suitable guide equipment should be considered before extended tracking or imaging use.
