Features

  • Integrated Explore Scientific PMC-Eight system that transcends the industry standard single processor by utilizing eight CPUs that operate independently of one another to focus on defined functions, which results in superior responsiveness, efficiency, reliability and astoundingly fast timing intervals.
  • Clutched dual-axis worm gears with quiet precision stepper motor belt drives
  • Intuitive ExploreStars app, which is available for Apple, Android and Windows tablets, that makes it simple to operate the GOTO system. Through it, users can quickly align their telescope, navigate the stars and learn specifics about tens of thousands of celestial objects
  • Clutched RA and Declination axes are smooth and allow for precise balancing which makes the process of repositioning your telescope efficient
  • Polar alignment sight hole through the RA axis and precise altitude control for fast alignment without polar scope.

Description

You’ve found the perfect spot with ideal seeing conditions, and your eyepiece is waiting to unveil celestial treasures. Instead of diving right into observing or imaging, you can quickly whittle away precious time manually locating and tracking specific objects as they move across the expansive night sky. That’s where Explore Scientific’s iEXOS-100 GOTO system comes in! With the iEXOS-100 GOTO tracker mount in your arsenal of astronomical tools, flawlessly navigating the sky has never been easier. It utilizes a proven German equatorial mount design and an integrated version of our revolutionary PMC-Eight system that transcends the industry standard single processor by utilizing an 8-core microcontroller with eight CPUs that operate independently of one another to focus on defined functions. This delegation of tasks among the processors results in a system that offers superior responsiveness, efficiency, reliability and astoundingly fast timing intervals for smooth image acquisition and accurate tracking. Although it is internally complex, the robust electronics that power this premium GOTO mount are easily managed from your own tablet or laptop using the intuitive ExploreStars app or through the ASCOM-powered software of your choosing. Our commitment to creating a streamlined GOTO mount is obvious in other design choices. The iEXOS-100 has smooth locking clutches that will let you quickly reposition your telescope from one side to the other and an altitude knob for smooth height adjustments. The mount base includes a small polar alignment tunnel that allows users to roughly align their observing setup with Polaris. It also has a simple bubble level that comes in handy when stabilizing your tripod. Other features include a bracket for holding the battery pack, which powers the PMC-Eight system through 8 C batteries (not included); two 1 kg counterweights for balancing (telescopes and accessories that weigh more than 6 pounds will require additional counterweights); and glow-in-the-dark markers on certain points of the mount and tripod so you can stay oriented with your setup at night.

  • GREAT MOUNT SO FAR...
I have not had a change to use this mount a whole lot so i will update more in the future. As of right now the mount seems to be rock solid. It holds my Orion Eon ED80 , 50mm guide scope and dslr just fine. The counter weights were just a few ounces too light to balance it so i added some sticky car tire weights to them. The Explore stars app is only available through the Microsoft app store. Which was tricky to get it to work but after some great help from Explore Scientific i was on my way. This is my first telescope and mount so i dont have a ton of experience. After initial alignment and setup it was smooth. I have not done any photography yet with this mount due to bad weather. I should be able to get some done this weekend and will post an update. Over all for the price and quality and support i dont think you could find a better comparable mount for the price. Update: I orderd this item on July 26, 2019. It is now May 2 2020. The Mount its self is well built for what it is. The major problem i have is to make it functional you have to spend a ton of money. I had to purchase a polar scope for it. Which has next to no instructions. No real way to have it in the same spot each time you take it out. Which was not available at the time of purchase. At the price of approx $90 shipped. You have next to no azimuth adjustment. However they will sell you an adapter for $100. They also offer an upgraded tripod for the mount. At a cost of $250. Which requires the special azimuth adapter in order to use it. If you buy this mount and all the other items needed to make it stable and functional you would still not be able to do much. Because the software is complete trash. Tried on several android devices. Half the features dont work. Crashes all the time. Same with windows laptop. The software also makes fine tune adjustments impossible because you cannot look through a scope and look at a monitor at the same time to see where you are doing. So by the time you are done spending 800.00 on this setup you could just buy a mount that will hold more weight and be more functional. The only redeeming quality is its light weight and customer support is fast to reply. I have not been able to get this mount to properly function with any software i used. (PHD2, APT, Explorestars ) I did the latest firmware update. I purchased a new mead lx mount . I was up and imaging with in 10 minutes of setting it up outside. ... show more

  • Worked PERFECTLY with my ASIair Pro. Tracks as good as my CEM26.
Great design lightweight mount handles 19 lbs max. Worked PERFECTLY with my ASIair Pro. Tracks as good as my CEM26. I only pulled the lower legs down around 40% of the way for better stability, and I'm extremely happy with this mount! A little louder when slewing than I'm used too, but quiet as a mouse when tracking. My RedCat51, mini tracking scope, and ASIair Plus connected required an extra weight to balance [I already had from another mount].. Carrying a total of 14 lbs including counter weights and what an awesome and easy setup. Waiting on the iExos-100 Azimuth adjuster adapter to get in.. but was able to align it pretty well without it - using my ASIAIR Plus 'all sky alignment' method, but I prefer the more intricate adjustement screws for quicker accuracy. I can't BELIEVE this had a one day flash sale of $299.99. WHAT A DEAL. ... show more

  • Good, but complex
Difficult to use at first - very German, I would say. The software is kinda trash in terms of UI, but it does work. Once I figured it out (after about two nights), it worked quite well. It's definitely a smaller unit, but it is very stable when holding a smaller telescope. It was also fairly easy to assemble (keep in mind that it requires EIGHT C batteries). I would definitely recommend it, however, especially at its price point. ... show more

  • Apps are not good.
After more than 14 hours of trouble shooting I was unable to get mount to connect to ExploreStars envision (Android), Legacy Explorestars connects but the 2/3 star alignment part of the program is broke. Unable to do an alignment. The mount seems like it would be great for using with Ascom, it tracks great when polar aligned and synced to one star. I am giving this one star because I wanted a small mount I could put in car and control with Android, this mount does not do that. ... show more

  • Explore Scientific has no functioning Customer Support
This is a beautifully made mount. However, after a couple days, it ceased to talk to the Android tablet and PC that are used to control it. Explore Scientiific has no customer support; at least they do not respond to phone calls or Trouible Tickets. I finally got hold of someone who worked with me and said it to them for repair. Today, I am told their technician is running a month behind. Had I known how this would go, I would not have bought this mount. They have had it well more than a month now. No contact, mount not repaired. I will never buy Explore Scientific again. It appears the mount is very demanding of voltage. In addition, both of apps they provide to control it are flaky and somewhat random at making and keeping a connection. It took a couple of months of frustrating investigation to figure out how to get the Explore Stars app to reconnect. You need to stop the app or it will not reconnect. It is now working. This is a neay and elegant small goto mount for telescopes that weigh ten pounds or so. It would be nice if it had a hand controller but at this price there is nothing significant to complain about except rhe learning curve for the app. ... show more

  • Not Recommended
This thing has a HUGE learning curve and needs a lot of extras they don't tell you about. Worst polar alignment method ever. Trying to gather relavent information on using it is like looking for a needle in a haystack. The website for ExploreScientific is disorganized and most YouTube instructional videos are over 5 years old. I finally managed to make it work as a simple tracker but unable to figure out all of the other features it claims to have. Look for something else if you can. ... show more

  • Great
Great, it meets expectations. 3, 4, or 5-minute lights with guiding via PHD2/Ekos and no tracking issues. In my case, I use StellarMate and zero problems (my only complaint: with Ekos connected via cable, it is much, much more stable than via Wi-Fi. However, to achieve this, a small and secure configuration is required to enable the mini USB port, which doesn't come open from the factory. It would be easier if it were already included to make the connection right away). ... show more

  • Lightweight Autoguiding Capable Goto Mount
I had pretty low expectations of it considering the price, but I was pleasantly surprised at its performance. It carried my Redcat51, 533mc pro, sv165 guidescope and 122mm guidecam like a champ, getting around 1.5 arcseconds variation in the ASIAIR's PHD reading. I think with a slightly lighter OTA or camera, or maybe an additional weight to balance the assembly better on the RA axis it would perform much better. Also polar alignment would be easier with the optional azimuth plate. But all in all, I'd consider this mount an absolute steal. It's significantly quieter than my other mount and is very easy to connect to a PC or ASIAIR to control it. I haven't used the included app so I can't comment on that. It's so nice to have a quiet, light mount that can autoguide and be run by my usual software. Here's my proof, a 2 hour image of the Crescent Nebula in HOO narrowband taken from a Bortle 7 location.
