The Zhumell Z10’s specifications include a 254mm aperture, a focal length of 1250mm resulting in a fairly wide focal ratio of f/5. What Do The Zhumell Z10’s Specifications Mean? They can’t double spotting scopes unlike the other 2 variantsĪs a whole the optics found within the Zhumell Z10 are very solid with its cons only really being minor annoyances which you definitely will look past (to some degree) the further along you get using telescopes and learning the tricks of the trade.Can’t view things on earth very well unlike the other 2 variations.Low focal ratio reflector devices tend to suffer a lot more from comatic aberration.You’ll regularly need to collimate the device too as they’re easy to knock out of alignment.The optics are exposed meaning you’d need to clean them up regularly.These optics don’t suffer from chromatic aberration.Reflectors are generally cheaper to manufacture, resulting in cheaper telescopes. Great for viewings faint objects in the sky as all types of light can pass through the lenses (this isn’t the case for a refractor).The pros of the optics found within the Zhumell Z10 : There are also 2 other core optics you can find within telescopes, namely refractor and compound optics but I won’t be covering them in detail here (if you want a more detailed look though, click here to read an article we’ve written on the subject) but, I will compare the pros and cons of a reflector to them. The great thing about these optics when compared to a cheaper spherical mirror is that Newtonian reflectors don’t suffer from spherical aberration. The Zhumell Z10 uses reflector based optics within its tube, particularly a Newtonian reflector which uses a higher quality parabolic mirror design. As your object begins to drift across the sky, the new adjustable azimuth bearing system facilitates smooth, even motion for tracking objects.$1,596.95 Check Price On Amazon How Do The Zhumell Z10’s Optics Work? Then, lock your view in place with improved manual clutches. When you’ve centered your target in the 8x50 finderscope and your eyepiece of choice, bring it into razor-sharp focus with the dual-speed Crayford focuser. Once you’re set up, push the scope on its ball bearings toward your desired object. A primary mirror cooling fan brings the telescope into thermal equilibrium quickly so you can enjoy long viewing sessions without delay. A durable, sturdy construction means your Zhumell will stand up to years of use at public star parties, camping trips, and more. Great mechanical performance and sturdy constructionīeyond the optics, the rest of the Z12’s design is simple and streamlined. With the Z Series, Zhumell has put your money where it belongs: into the telescope’s optical system. You’ll also get two fully multi-coated eyepieces: a 2” 30mm eyepiece for wide field views and a 1.25” 9mm eyepiece for higher magnification. The Zhumell Z12 Dobsonian telescope features a massive 12” parabolic primary mirror that captures a substantial amount of light and produces crisp, bright images free of visual defects like spherical aberration.
