Zhumell 8x42 Short Barrel Waterproof Binoculars I'd avoid the Zhumell Z130, according to the folks at telescopes.com, there isn't any way to collimate the primary. I can always purchase higher quality eyepieces later on. The main difference between this telescope and others of its size is the collapsible “FlexTube” functionality. Now that I write it out like that I'm favoring the XT6 Plus and Skyline over the Apertura. Would be used as a finder eyepiece to star hop with, in conjunction with the red dot sight). Apart from the price, the size is bigger than what I can handle. According to a few sources the optics for both scopes are identical. I have one and store it on a shelf. You can just eyeball the secondary mirror to make sure it's centered under the focuser and that the primary mirror is fully visible, and then just do a simple star test of the collimation of the primary mirror. It's a toss-up whether a 6x30 straight-through optical finder is better than a reflex sight, so I don't know if that's really an advantage. For the DT6, I don't see what it offers over the regular XT6, and the regular XT6 is $30 cheaper. Hypothetically, if I were going to get a 6" instead, it would most likely be between the Orion XT6 Plus, the Skyline 6, and the Apertura DT6. People worry way too much about CO's in standard scope packages. I haven't heard anything good about the helical focuser included with the OneSky either. I have the OneSky, and I actually need the truss design, because I transport mine as baggage when I fly on vacation. I know creating a shroud could help with this, but honestly it's something I would rather just not deal with. I am strongly looking at the Z130 as well will0wtr33 as a grab n go scope to start my stargazing journey. What a beauty. I've also heard people complain that heavier eyepieces can cause the truss rods to sag and effect collimation. Feel free to discuss anything here, from what sort of telescope you should get, to how to actually use that scope of yours! Planets will stay sharp throughout most of the field of view as they drift across it. At MOST, a $7 colllimation cap to aid in the collimation of the secondary mirror is all you need. Edited by CrazyPanda, 15 January 2020 - 09:01 PM. They're all going to be optically and mechanically similar. I think the XT series optics are made by synta, while the DT6 and Skyline are GSO. At any rate, one thing to consider about getting a table-top dob vs a full size dob is what you put the table-top dob on. If anyone has any last minute advice, suggestions, or warnings PLEASE let me hear them now. It will be easier to add a finder with magnification and a equatorial mount with the Zhumell. The details the 114 provides on brighter galaxies, nebulae and clusters goes far beyond what I would expect. According to a few sources the optics for both scopes are identical. I'm ready to pull the trigger, and plan on ordering this coming Friday. The diff in Central Obstruction will be insignificant compared to the advantage in field dimensions gained via 2" eyepieces' larger field stop. If you don’t need the collapsing tube, then absolutely get the Z130. 2. $79.99 Zhumell Z130 Portable Altazimuth Reflector Telescope. The SkyWatcher FlexTube 200P is an 8” f/6 Newtonian (203mm Aperture, 1200mm Focal Length), with the same optics as those found in Orion, Apertura, Zhumell, SkyWatcher classic, and GSO dobsonians. The SkyLine 6 and DT6 do have slightly nicer focusers though. All extended objects like nebulae and galaxies will be 20% larger at the same brightness, or almost 50% brighter at the same magnification as the Z130. Funny, I’ve never had an issue with the helical focuser. Yes, the scope is objectively smaller, lighter, and easier to carry, but you'll also have to potentially build and at least carry a sturdy tri-legged stool for it to sit on to bring it to a comfortable viewing height. Folks like Zhumell sell packages that work. I figure if I get really into the hobby I'll save for a 10" or 12" in the future. Afters tons of helpful advice from the wonderful members of this forum I plan on purchasing the Astro Systems light pipe/sight tube combo tool for collimation. Amazon.com: astronomers without borders onesky 130. The payload rating for virtuoso is 7.7 or 8.8 (slightly varying info out there). According to most of what I've read the only advantages of the OneSky seem to be the charity donation they make when one is purchased, the quality of the eyepieces, and the included collimation cap. You could get away with even the 3.2mm focal length from that line for nights when the atmosphere is nice and steady. The groundbreaking Z Series Dobsonians from Zhumell have been a revelation in the world of amateur astronomy. I didn't know the z130 can't be collimated, that's really a downer :-(. The Zhumell is probably a few ounces heavier. Those 2 will outperform a sack full of meh eyepieces every time. The z130's base looks nice (grips, eyepiece holder) and the focuser looks decent (though entering the optical path a bit). Yes, taking good advantage of the 2" focuser means a larger CO to illuminate the larger field stops. 3. The spider vanes are also thinner then what you'd get on the OneSky, so it'll have a little more contrast, and a more traditional diffraction spike pattern (which I quite like). Do you know of any significant differences off the top of your head? Basically the reason I recommend just the plain old XT6 is because it's the cheapest way to get just the scope, leaving you the most money to get some nicer eyepieces that can give a better viewing experience. Zhumell binoculars, telescopes, and accessories consistently earn high marks from reviewers for uncompromising optical quality at affordable prices. If you get the 5", then later you can skip the 6 or 8 and go to a 10" for your next scope. It was an enjoyable scope, easy to use with very surprisingly good optics. Press J to jump to the feed. Beyond the optics, the rest of the Z12’s design is simple and streamlined. Afters tons of helpful advice from the wonderful members of this forum I plan on purchasing the Astro Systems light pipe/sight tube combo tool for collimation. I frequently would accidentally touch the focuser tube of my Celestron Omni XLT120 (made by Synta) and found it preferable to rub my fingers in the dirt if that happened. I have pored over the specs, and I keep coming back to not knowing which one is a better choice. Edited by vdog, 20 January 2020 - 10:33 AM. Same OTA, but 2" focuser and a good red dot finder. Celestron provides services including importing, warehousing, and shipping the AWB OneSky … After about two months of research I believe I've found my ideal first scope, the Zhumell Z130 (a 130mm aperture f/5 tabletop Dobsonian). I often see people saying $200 telescopes--4.5" and 5" aperture telescopes such as the AWB OneSky, the Zhumell Z130, and the Orion StarBlast 4.5--is the minimum price of entry to serious amateur astronomy. I’ve found if I use a different eyepiece and have to raise the focuser up a bunch to achieve focus, it isn’t as good. So between this and point #2, you will have a nice clean FOV to work with. The F/8 focal ratio will be a lot more forgiving on cheaper eyepieces. Zhumell 10x42 Short Barrel Waterproof Binoculars. Can use the extra payload capacity for eye pieces and put a simple camera! If anyone has any last minute advice, suggestions, or warnings PLEASE let me hear them now. Then I showed them a really good M31/32/110 with an ES68 24mm and the OneSky. If you’re looking for the most portable budget telescope, the AWB OneSky is the best option and it comes with a Cheshire collimation eyepiece.
