Built for beginners or experienced amateurs, Explore Scientific's white EXOS-2GT Motorized Equatorial GoTo Mount helps take the guesswork out of astronomy and gets you observing faster by combining an equatorial mount and stainless steel tripod with a computer control system and precise dual-axis motors. The mount is designed for refractors of up to 152mm (6") aperture and reflectors of up to 203mm (8"), with a maximum payload capacity of 28 pounds. It features a Vixen-style dovetail saddle for compatible optical tube assemblies (OTAs) and an integrated bubble level to assist in leveling the mount during setup.

The SkyTracker kit includes the hand controller unit and right ascension and declination motors. Its hand controller has a database of more than 272,000 objects with the ability for users to input custom coordinates and favorites. With a slew speed of 2°/second and nine tracking speeds, the SkyTracker can accurately keep near- and deep-sky objects such as the Moon, planets, galaxies, and nebulae centered in your eyepiece for long-exposure imaging and astrophotography or prolonged observation sessions.

The tripod is built with large 2"-diameter stainless steel legs and tight tolerances to reduce vibrations for clearer viewing. A center stabilizer bar pulls the accessory tray up to lock the legs in place, adding further rigidity and vibration reduction. It is adjustable from 26.8 to 42.5" to accommodate a wide range of users and features large thumbscrews for tool-free adjustment in the field. An adjustable tray is also included with the tripod to keep eyepieces, flashlights, and other accessories safe and at the ready.

    EXOS-2GT Motorized Equatorial GoTo Mount with Tripod (White) is rated 3.0 out of 5 by 7.
    Rated 1 out of 5 by from Missing parts and doa Received without the battery carrier. Email B&H about that and Michael replied it does not come with batteries. Indeed, I am very much aware of that, however the 12v carrier box to put the batteries in and power the mount is missing from the container as I described in my email to B&H. I call my friend that recommended the mount as he owns one and he brought his battery pack over and we plugged in controller, power etc and nothing, Does not work.

    Rated 2 out of 5 by from Not so great. Not recommended. This is beleived by many to be a relabled Meade LXD-75. It is not. The mount body (the cast parts) basically are, but the motors are not, the control boards on the motors are not, and the hand controller is an iOptron clone...not even a relabled iOptron authentic device. The goto is inaccurate, even with a fantastic polar alignment and a 2 or 3 star alignment. The tracking is outstanding... once you get it to find an object to track. But it the goto is simply horrid. ALWAYS at least an hour or more off in Right Ascension, and way more than a full degree of Declination. Mine has a terrible habit of suddenly, without warning, losing it's mind and sending the telescope at full speed around in RA toward crashing into the tripod. I've had to cancel slewing in a panic more than once to save my telescope... once, when I couldn't get it to cancel with the cancel button (-), I was barely able to turn the power off just moments before it slammed my scope into the front tripod leg. If you don't mind fighting your scope more than you view or image, go for it. If you'd rather have a reliable rig, get something else.

    Rated 4 out of 5 by from Good mount for the price. Free 2-day shipping: gotta like that. Unit seems well built and seems to work fine; just a couple of issues. First, as far as documentation there's only a 3-4 page all pics document showing how to assemble it. You can eventually figure it out, and you can download a complete manual from Bresser, but it would have been nice to actually have a manual on paper, DVD, whatever. And the arrows used to align the mount in the RA and Dec home positions are white on white and kinda hard to see in low light. A sharpie can fix that easily enough. All in all a really good value.

    Rated 5 out of 5 by from Highly portable, decent guiding performance, and good price. I've owned or adjusted for mounts of this class (CG-5/LXD-75) over the decades so I knew what to expect by way of performance. I bought this to replace a heavier GOTO mount by another manufacturer that I sold after using it for nearly 8 years, mostly at a remote location (where it was stored). When it came home it was redundant with another mount. I am very pleased with the performance of the ES FLEXOS-2gt: With only minimal adjustments to the worm gears it now guides to about 2 to 3 arc seconds RMS. The factory had tightened the backlash down too much on both axes (probably in response to customers gripping about too much backlash), so I had to reset that. While doing so I observed that the axial bearings on the worm were also too tight - with the worms removed (but still in their bearing blocks) you could feel the individual bearings vibrate as you turned the shaft by hand. They had been adjusted in a effort to reduce axial play. But the factory techs overdid it again. That was also easy to adjust out - the human hand is delicate instrument. If purchasers don't know how to do this already there is lots of information on the web for free on adjusting CG-5 clone mounts. If you don't need to adjust your mount when it is new you will need to learn how to do it someday when the mount needs (minimal) maintenance. With only these minimal adjustments I was able to take five minute guided frames that had no discernable blur to the stars (see the picture below, taken Sept 15-16) at a focal length of 400mm and speed of f/4. Five frames were stacked to get a total equivalent exposure of 25 minutes. Guided with PhD software and a QHY5-IIC guider through an old 135mm telephoto lens converted to a guider. The imaging rig weighted in at 15 lb. At this price point (or even 2-3X the price) I fully expected to have to make these adjustments. It is also important for the purchasers to have reasonable expectations - stick an 8 inch Schmidt Cass on this and you will probably be unhappy since your focal length will be 2000mm - that is a demanding focal length (very sensitive to guiding errors, the atmosphere, you name it), not to mention requiring long exposures due to the slow stop of f/10. With a little more adjustment, cleanup and re-greasing (again, something every mount of this class needs to have done sooner or later in my experience) I expect to be able to image with a 6 inch f/4 or f/5 (600 to 750mm focal length) routinely with weight in the 25lb range. Maybe even an 8 inch f/4 but that would be gravy to me. The only real CON to this mount is the slow max GOTO speed of 2 degrees per second. But that has a PRO side of it - the batteries will last longer. Yes, it would be nice if the ports for the modular jacks were labeled but a label maker fixes that in 2 minutes. The two-page front and back assembly instructions show you the correct way to plug them in initially. The lack of a manual in the shipping box (or at the Explore Scientific website) is annoying but there are older versions on-line that can be found with a little searching. And the user interface is pretty intuitive. I had to order a battery for the odd-ball one the Real Time Clock uses (CR1220) as I didn't have any. Online they are cheap - at local battery stores they are outrageous. Easy to put in the hand controller. Just work carefully. Since the mount is so compact and light I can leave it set up in the garage (without counterweight and optics) under a grill cover and carry it out with one hand. The tripod, compared to all the earlier mounts of this class I've had or adjusted is rock solid. And it is pretty. Very happy I purchased this. As usual the delivery service with B&H was exemplary, nicely double-boxed in a single case, and the price was very, very reasonable. Makes you wonder why all the other similar mounts cost so much more. When the polar scope (backordered) arrives my joy will be complete.

    Rated 1 out of 5 by from Total Junk Mine arrived DOA. Shipped it to Explore Scientific for repairs. Got it back and it tracks okay but slewing is another matter. Sometimes for no reason, it will not stop slewing and slams my scope into the tripod legs. Just learned today from ES that the hand controller can not be connected to a PC or Mac. They said it burns up the circuitry. That is great to hear after I owned it for three months.

    Rated 4 out of 5 by from Nice mount with nice features This GEM mount does what it is supposed to do at a nice price point. The $350 un motorized Bresser model shows how low cost it can be; however, the mechanicals are quite nice just the same and can hold a heavy load. I'm really liking the white paint as the scope I use is white and observe from the culdesac in front of my house. I purchased this scope for a big 6 Apo refractor so I won't comment on rigidity as my goal was to get a strong enough scope to carry a heavy load BUT NOT BREAK MY BACK. This mount with Goto totals 41# which is only a third the 120# CGEMDX I would have used had I decided to spend money at the emergency room instead. First off, Explore Scientific bought Bresser and so although identical, I purchased a Bresser labeled EXOS-2GT but the names don't change anything. The Goto system is nice and I like the four rows of info on the hand controller screen. So far, the alignment and tracking seem pretty good although I've not challenged them very hard. I've also got a Goto from Meade, Celestron, and Orion, and the Exos learning curve is easy. I do wish it maintained a clock and location but it's a mere minute to insert. Mine came with a polar scope that uses stars near Polaris for more accurate alignment but I can't see them in my light polluted skies. There was also a short in the lighted reticle battery but it was an easy fix to bend the little spring. Mine may have been the last Bresser in stock as it is no longer listed; just Explore Sci. Anyway, a little screw was installed wrong in the motor cover and the red stripe tape was peeling off the counterweight. Small details. What would make it better? Although I wished for a cigarette lighter adapter so I could run a power pack, the D-cell pack means everything is lighter (no big battery to drag out). With its high load capacity, I also wish it had a Losmandy dovetail. I'm spending money on an ADM dual dovetail adapter. I also wish it had a holder for the hand controller.
