explore scientific ed80 review

You’ll also need to supply your own finder scope as it doesn’t come with one. While I’ve never had any real issues focusing, this spongy feel results in it taking more time to focus than is necessary. Loosening the lock nuts causes the whole focuser assembly to wobble in the scope tube. After a couple of initial uses, I found that the hex bolts that hold the dovetail plate on the scope started coming loose. I easily and permanently solved this problem by putting in some semi-permanent thread lock on the bolts before re-inserting them, but I shouldn’t have had to do this. The ED0806-01 is small, lightweight apochromatic refractor featuring an air-spaced triplet optical design and true diffraction-limited optics. When I first began taking pictures of deep-sky objects through my telescope, they were shaky images with bloated football stars and poor focus. The model available from Explore Scientific had the specifications I was looking for, at a price I was comfortable with for my newfound hobby. Small and portable, it’s an ideal grab-and-go telescope. When not in use, it all packs away securely in the padded metal hard-case. Even the slightest breeze would jiggle my bulky Schmidt-Newtonian, thereby ruining my current 3-minute exposure. The dual-speed, Crayford-style focuser is ultra-solid and tightly locks my DSLR camera into place while imaging. The spacing between the dovetail and tube is too small. I am so happy with the performance of the 80mm version, that upgrading to the Explore Scientific ED102 Carbon Fiber version was a no-brainer. This scope’s small size and weight make it an ideal “grab and go” scope. Focal Ratio: f/6. It was by far the best view of M31 and its companions I’d ever seen. And there’s a good chance that once you lock it back down in its new orientation, you’ll need to tweak the focus again. Once focus is achieved and the drawtube is locked into place with the thumb screws, it holds focus accurately over an entire imaging session. Views of the moon are clear with great contrast and no chromatic aberration at the edges, even at advanced stages when the moon is very bright. When the very first frame appeared on the back of my DSLR display screen, my jaw hit the floor. The diffraction-limited optics are appreciated when exploring the lunar terrain or using a high-powered eyepiece to view Saturn’s rings. Review: Explore Scientific “Essential Series” ED80. I have not been able to achieve images of this quality using a Newtonian telescope. After a quick adjustment using Sirius as my alignment and focus star, the illuminated reticle finder scope was a pleasure to use and to center my target in the frame. You’re much better off loosening the compression ring attaching your camera, rotating the camera and tightening it back up than you are using this feature. Explore Scientific ES 80 ED Triplet APO Review Image 1: Explore Scientific is known for refracting telescopes, quality eyepieces, the David H. Levy Comet Hunter, a Maksutov-Newtonian telescope and Twilight I and II alt-azimuth mounts. The Explore Scientific Essential Series ED80 (model # ES-ED0806-01) delivers the goods with solid construction and great optics. While the image is cropped, you can see some comatic aberration in the corners and the focus isn’t as sharp at the edge of the field of view as the center compared to my other images that have a perfectly flat field and are free of all coma. Shooting the moon with my Explore Scientific ED80 and Nikon D750 on my Celestron AVX. One very notable exception is for collimation. The precision focuser knob comes in very handy when focusing my camera using the “frame and focus” (FWHM) tab on BackyardEOS. For visual use, it produces bright, sharp images with potentially gigantic fields of views with long focal length eyepieces. You won’t be disappointed. This is a beginner’s review of the Explore Scientific ED80 Triplet and a few assorted accessories. I would recommend swapping the finder shoe for a Synta type and getting a padded plastic box to hold it. The “foot” Vixen dovetail mount is attached to the scope via a pair of hex bolts and a small riser block. The high-quality glass design of an apochromatic refractor reminds me of a high-end telephoto camera lens. None of these will impact the user significantly, but they do need to be pointed out. I must confess that I am not an expert when it comes to comparing the visual performance of telescopes. This scope has also become a favourite for shooting the moon. You don’t get a lot in the box, but you certainly get what you need and what you get is of good quality. At that time, I had no idea that this telescope would be my ticket to a lifelong ride in the world of astrophotography. The only thing you’ll be missing out on with a small telescope of this size is the visual observing power and increased magnification that comes with an instrument with a larger aperture. It has a few shortcomings and compromises that keep its price affordable, but overall, this fine instrument will fulfil the needs of the most demanding photographer without breaking the bank in the process. On paper, this looks like a great telescope that delivers all that’s required for both visual and photographic use. Explore Scientific offer FREE lifetime collimation service for this telescope should it ever need it. While accurate and smooth, the focuser has a very “spongy” feel to it and is not as responsive as I’d like. The contrast on the fine surface details is far more pronounced on this scope, despite the higher resolution and power of the larger instrument. M78 – Reflection Nebula in Orion using the ED80. I am certain that they feel the same way. While there’s technically nothing wrong with the scope, this is where things could have been done better and a few places where corners were cut to keep the price low. With a focal length of 480mm, this high-quality instrument can easily fit the entire Andromeda Galaxy in a single field of view, as well as M8 and M20. The faster f/6 optics of this triplet design offer advantages in terms of both physical size and the potential field of view. The carbon fibre construction not only looks great, but is extremely lightweight for something so large, weighing in at about the same as the 1.25 diagonal that came with my Meade LX90. It is solidly built, has a smooth 10:1 focuser, an illuminated 8x50 erect image finder and comes with an impressive case and 2” 99% diagonal. I own a Twilight II mount and enjoy using it with various small refractors and my 6-inch f/4 Newtonian reflector. While no apochromatic refractors of this aperture in this price range is perfect, this one is a definite step up from others brands in terms of performance. This design virtually eliminates chromatic aberration and delivers razor-sharp, high-contrast images with excellent colour. While I highly recommend this scope, I would encourage that if you can afford the extra 300 USD, the 102mm version is a much better buy and the issues I’ve pointed out with this scope aren’t present on the larger model. The visual performance of this scope is excellent, especially when viewing bright planets or the moon. I highly recommend the ED80 to beginner to intermediate astrophotographers looking for the highest possible image quality at an affordable price. A refractor in the 60-100mm range generally offers an extremely wide field of view, which is great most of the time. If you want a second opinion on the ED80, talk to anyone that owns one! The bands were clear and sharp and the Great Red Spot stood out clearly. One thing to note is that if you want to use this scope for photography, a coma corrector / field flattener is a must. 1 hour 45 minutes of integration time shot with a Nikon D5100. Chances are if you’re buying this scope, it likely isn’t your first scope and you’ll already have eyepieces. I have no doubt the ED80 can achieve its advertised resolving limit of 1.45”…. Fortunately, I have a lightweight camera (Nikon D5100), so declination balance isn’t a big issue. You’ll have to tweak the knob back and forth a lot to get perfect focus, as there’s a delayed response to your action, making it feel less accurate than it should. Tolerances for the machining here are very poor. My Explore Scientific ED80 on a Sky-Watcher HEQ5 GoTo Mount.
