Building on the success of their previous systems, the iOptron SkyGuider Pro EQ Camera Mount increases the precision and payload capacity while reducing the form factor to produce an imaging support system to track celestial bodies and capture images of the sun and moon, or for wide-field astrophotography star-scapes shooting techniques. This versatile tracking system can be configured in multiple ways including single or double-camera mounting, or even mounting smaller telescope optical tubes.

The system functions as an equatorial mount, with a Right Ascension (RA) tracking motor to compensate for the apparent movement of celestial objects across the sky. An integrated polar axis alignment scope aids in accurate set up to improve tracking accuracy for long-exposure photography. A Declination mounting bracket allows the use of the counterweight kit to balance heavier imaging rigs, and limit vibration and strain on the motor and gears — or for double-mounting cameras, or OTAs. The tracking head runs on a factory-installed rechargeable battery with a 20-hour runtime. iOptron offers the SkyGuider here with just the tracking head and alt-az base for users with a reliable support system. The tracking head can be mounted on a tripod by itself using a conventional 1/4"-20 photo ball-head, or the head/base can be mounted together on most astronomical, photo, video, or field tripod using the 3/8"-16 or 1/4"-20 mount on the bottom of the base.

    SkyGuider Pro EQ Camera Mount is rated 4.8 out of 5 by 12.
    Rated 4 out of 5 by from Planning to use for the Eclipse and some astrophotography This item is very well-built and durable and once set up it appears to work very well, practicing for the Eclipse. Only challenge is the instructions are not necessarily super-intuitive and I'm pretty good at following instructions. My setup looked a little different than the photos, however it appears to work just fine. Biggest challenge as I am not familiar with astronomical terms (specifically when it came to the polar alignment), and planning to use it during the day, is more difficult to figure out. Had to watch several YouTube videos until I understood I was over-thinking it. May not be perfect, but will surely allow me to enjoy the event without monitoring the camera the entire eclipse!!

    Rated 5 out of 5 by from Excellent sky tracker for DSLR and lens. This model sky tracker comes with a counterweight and declination mount. It is very convenient for heavier cameras and lenses, e.g., a DSLR and at least medium length zoom lens. Lighter cameras can attach with a ball mount (separate) for a very compact package. I found it easy to align the mount to Polaris using the built in polar alignment telescope - you do have to get Polaris within the alignment telescope's field of view by leveling the mount, setting your latitude and using a compass with magnetic offset. One minor issue: with the full setup (counterweight and declination mount), you can't control the orientation of the camera - it's like a telescope in that regard, but without the ability to rotate the focal plane. I found tracking to be very accurate, and I'm very happy with the device.

    Rated 4 out of 5 by from Buy this product but do your homework first! Despite some idiosyncracies, this mount gives good results. I like the fact that the Head (the tracking motor and gears) can be separated from the Base and can be used independently if desired. The Base altitude lock is easy to use and the altitude fine adjustment knob is large enough to provide a good grip. Unfortunately, when a load (camera and counterweight) is added to the mount, the altitude knob becomes difficult to turn, and the pole star shifts abruptly while setting up. (There is some play between the worm and the worm gear. As far as I can see, this cannot be adjusted.) The azimuth locking knobs are small and situated up against the Base, thus difficult to loosen and tighten, especially in cold weather. Azimuth fine adjustment screws work well, however. The fact that the polar alignment scope rotates with the RA axis is a bit disconcerting, but alignment holds if one is careful. Because I have a fairly heavy camera and 135mm f/2 lens (approx. 2 kg - 4.4 lbs. total), I opted to attach the CW and CW shaft to the DEC bracket (long side). This configuration counter balances nicely for regions at high declination. For regions at low dec, however, extra weight beyond the supplied 1.35kg CW is necessary. Also, because polar alignment requires that the Base be tilted to an angle equal to the observer's latitude, dec adjustments with the ball head are limited, and some regions cannot be reached. I solved this problem by ordering a Manfrotto junior pan/tilt head, which has extended 180 degree front tilt. The tracking motor operates continuously once the power is on and makes no noise whatsoever! Fast motion RA buttons make framing a region less difficult. Success rate for pin-point star images for 5 min. exposures with my 135mm lens is about 50%.

    Rated 5 out of 5 by from It's awesome! I'd buy again. Works incredibly well. With the counterweight, it easily supports and rotates my canon 5D plus 100-400 zoom.

    Rated 4 out of 5 by from Light, accurate, travel mount for long lens astrophotography I purchased the Skyguider Pro EQ mount as part of a travel astrophotography system. The other portion was the iOptron 1.5” Field Tripod. The two together can be packed in a carry-on bag with plenty of room for other items. This tripod and mount are used with my Nikon D610, Nikkor 300mm f/4D ED IF AF-S, and TC-20E III 2x converter. The combination provides a very sharp, affordable, 600mm lens, though with and aperture of f8. I stabilized this long lens combination with a Manfrotto telephoto lens support, rather than the flimsy collar that comes with the 300mm lens. �I used this combination with my AVX mount in August to capture the time lapse video shown in the link below. � https://drive.google.com/file/d/0B82Wm2n8gY52Q3FSUkgtU2VnQ2c/view?usp=sharing � Lugging all the equipment for that shoot took two large, overweight, checked bags. After the trauma of having TSA rifle through my meticulous packing, twice, I decided to try another approach. � The new system is light and compact enough to bring as carry-on luggage. The real question was whether it was sturdy and accurate enough for serious astrophotography. I have now had it out for solar, lunar, and stellar observation. The first thing I noticed was that I needed a larger counterweight. I added another 3 lbs, which balanced the camera very well. The second thing I noticed is that the short length of the tripod means lying down on the ground to perform polar alignment. Still, I have never had such an accurate polar alignment just using the North Star. I normally perform two iterations of drift alignment after I do my North Star preliminary alignment. � On my first excursion I tracked the sun for about an hour. I noticed that the battery alone tracked accurately, but that it sped up slightly when supplemental power was attached. The error was about 2.5 arcsec per minute. This is not noticeable with a 30 second exposure, but could be a problem for longer tracking. For this lens and camera combination the pixel width is about 2.4 arcsec.� I next tried it at night, tracking the Orion nebula for 45 minutes. I had the supplemental power attached, so tracked at solar speed. After 45 minutes the image had moved only 10 pixels. This represents a tracking error of .54 arcsec per minute. Based on this error the camera should be able to take steady 2-3 minute exposures. The declination error during this period was only 20 pixels. That is pretty amazing for just a North Star alignment. The moon setting has a similar error when tracking with and without supplemental power. � I have definitely loaded this system past the recommended limit, and yet I am still getting very solid tracking. I am impressed that such a small and light unit can be so solid. � In three days I will flying out to Nevada photograph the Lunar eclipse. I will be tracking the shadow of the earth. The time lapse video will show the moon moving into and out of the earth’s shadow, like it is moving into and out of hole in space. �Pro: Light, accurate, travel mount capable of handling a long lens Con: Tracking speed changes slightly with and without supplemental power

    Rated 5 out of 5 by from This mount should be in your sky watching tool bag! This is a very nice, easy to setup and use tracker, The fit and finish are fine and the results (prior to the 2017 eclipse) have been astounding. If your doing astrophotography, this is a great and cost efficient way to work with a DSLR and telephoto lens.

    Rated 5 out of 5 by from Works well and not too tough to figure out Because I got this at the end of summer I've only had 2 real shots at using it so far. As someone new to astrophotography I fully expected lots of learning by trial and error. However the Sky Guider Pro has presented only little bumps in the road so far. I'm using a large ballhead that was already in my bag. Watch out when balancing the resulting setup so that when you point at a direction in the sky the weight of your camera and lens is working to tighten the head on the mounting screw instead of loosening it. Also if the polar scope is not almost vertically lined up the internal light will not illuminate the reticle. Instead of panicking that something is not right with the light, just rotate the assembly after loosening the clutch. Having said that things went remarkably easily. Locating Polaris at just the right spot in the reticle is fairly intuitive and quick. You can also easily and quickly touch up your alignment through the night if using the DEC bracket. The process has been sufficiently precise that I've gotten a high proportion of excellent circular stars taken with a 300mm lens for 3 mins at a time. If you want to run with a weighty supertele you may wind up having to get an extra counterweight shaft to achieve balance with just the one weight. Relatively experienced astro geeks at the same viewing site were quite impressed with these results. Get out there and have some fun.

    Rated 5 out of 5 by from Yes. Would buy again. Still putting this accessory through its paces. So far I have taken several 210 second shots, on various dates, with a 28mm lens and have achieved 3 to 4 pixel star dots, consecutively. That makes me happy. I'm learning about ISO invariant sensors so the tracker enables me to shoot at ISO 800 and stack multiples to reduce noise. Just be aware that now you can stop the stars, your horizon and foreground are moving. The unit is for the most part very sturdy and when tightened down, you can place or remove your camera, adjust your ballhead without disturbing the polar tracking. My only complaint is the latitude adjustment knobs and gear teeth don't tighten like the rest of the unit. I have to almost wrench' them down before it becomes stable. Since I have only used short lenses, I have not used the enclosed counter balance accessory yet. I don't think the lower cost units would be as sturdy. Overall, I would buy again.
