The 20mm Konig is comfortable to look through and offers a roughly 55-degree apparent field of view, which converts to a 2.4-degree true field with the 450mm focal length of the 114AZ. The Cometron 114AZ reflector telescope includes two 1.25” eyepieces: a 20mm Konig (labeled a Kellner but of a different design) for 23x and a 10mm Kellner for 45x. The tube is secured to the mount with a Vixen-style dovetail, which allows you to interchange it on any astronomical mount or tripod you wish in addition to the provided unit. To hold your eyepieces, the Cometron 114AZ features a 1.25” rack-and-pinion focuser, mostly made of plastic, which works well but may have some play/wobble when focusing. You will easily forget about the less-than-sharp stars at the outer perimeter of the field of view.Ĭollimation at f/3.9 is critical for achieving sharp images, but the Cometron 114AZ is easy to collimate, with the primary mirror requiring no tools for adjustment the rarely-adjusted secondary mirror will need a hex key. Unfortunately, at f/3.9, there is a fair amount of coma present, but this only affects the widest field of view and lowest magnifications you’ll also notice edge-of-field aberrations with the stock low-power 20mm eyepiece, but it’s not much to worry about. This telescope has a parabolic primary mirror of excellent quality, allowing it to provide sharp images of celestial objects-in sharp contrast to a spherical mirror, which provides fuzzy images. The Celestron Cometron 114AZ is a 114mm f/3.9 Newtonian reflector with a focal length of 450mm. Due to the price being identical to a 114mm Dobsonian with the exact same performance optically, we would recommend one such as the aforementioned units in lieu of the Cometron 114AZ if available. However, any tripod-mounted telescope at this price range is going to have some design compromises, and the Cometron 114AZ is no exception. The Cometron 114AZ is a nice enough telescope, and there are certainly far worse options. The Cometron 114AZ uses the same optics as other 114/450 reflecting telescopes like the Zhumell Z114 and Orion StarBlast, but atop a tripod instead of a Dobsonian mount, and includes a decent set of accessories to get you started. It provides amazing views compared to cheap small refractors and vastly outpaces the Bird-Jones or spherical primary mirror Newtonian reflectors Celestron is infamous for. Its 114mm aperture, wide field, and lightweight mount make it a great option for those looking to explore the night sky without breaking the bank. The Celestron Cometron 114AZ telescope is one of the better options for a budget telescope.
