Where to buy the Apertura AD8 8" Dobsonian Telescope in Europe? The SkyLine 8" Dobsonian telescope features a machined, 2" Crayford focuser with dual-speed adjustment control and smooth, backlash-free motion. Page 1 of 2 - Orion or Apertura 8 Dob - posted in Beginners Forum (No astrophotography): Hi! Post a FREE ad for telescopes, eyepieces, mounts, parts, and more. I'm a 65 year complete beginner who is considering buying my first scope, an 8" Dobsonian for use in my backyard. Since 2016 TelescopeTrader is where to buy or sell used telescopes and astronomy equipment. I'm thinking about getting the Apertura AD8 as mentioned in the title, since it seems to be one that is widely recommended. Can you give me some insight and/or advice on the Orion XT8 plus vs. the Apertura AD8. Hi, I'm new to astronomy and telescopes and know absolutely nothing, I'm currently reading through lots of posts and articles. The 8" aperture is great when observers want to learn the night sky without having a larger aperture where it may be harder to locate chosen celestial objects. This 8" Dobsonian telescope from Apertura is a great first telescope for those beginning astronomers who are looking to adventure through the night sky. The Dobsonian mount, popularized by John Dobson in the late 1970’s, is a very simple but effective method of mounting a Newtonian Reflector, based on the alt-azimuth principle. Page 16 Eyepiece Selection Your Apertura™ Dobsonian Telescope comes standard with two eyepieces: a 2” diameter wide field, low-power eyepiece with a 30mm focal length and a 1.25” diameter high-power eyepiece with a 9mm focal length. The fine-focus control knob allows you to dial-in details at a 10:1 ratio compared to the coarse focus knobs for ultra-precise focusing. I have narrowed it down to a 8" Dob and Im stuck between the Orion XT8 and the Apertura AD8. The optical quality is the same as any other 8″ Dob, but the whole package is so much better than the other 8″ models they are not even close to the Z8. I have been researching what to get for my first scope. Are there any advantages/disadvantages between them?Thanks!

Looking to see planets (Jupiter and Saturn) and other celestial sights. Is there a big difference between the 2 that a beginner like me would notice? Zhumell Z8(Apertura AD8), out of the box, is a mesmerizing tool for observing the Universe.
