Explore Scientific 127mm Air-Spaced ED APO f/7.5 Triplet Refracting OTA Telescope

The Explore Scientific 127mm f/7.5 ED APO Refractor Telescope is one of the most innovative ideas in high-quality apochromatic designs. Beginning with a tube fashioned from aluminum and stainless steel, what sets them apart starts from the inside. Explore Scientific uses advanced technology like its ED (Extra-low Dispersion) FCD1 (Dense Fluor Crown) glass, developed by Hoya Optical of Japan, to enable the production of lenses that offer superior sharpness and color correction by minimizing color distortion. This glass type offers a more durable and long-lasting solution to produce an optic to minimize chromatic aberration over delicate fluorite crystal objectives that are prone to fracturing and absorbing moisture. These true air-spaced apochromatic triplets have refinements like EMD (Enhanced Multilayer Deposition) coatings, which absolutely eliminates light scatter and maintains image contrast. Contrast is further enhanced with multiple baffles that mask and deflect unwanted stray light.

Upgrade your telescope’s ability by mounting the ED 127 to many popular equatorial and Altaz mounts, including Explore Scientific's new TwiLight I and TwiLight II Altazimuth Mounts. Photographers, who are looking for super high resolution optics, can mount the optical tube assembly to their existing medium-duty camera tripod. A release knob allows the tube assembly to rotate so that the camera can be positioned at any angle. The Universal Adjustable Mounting Plate of the ED 127 fits on mounts supplied by Explore Scientific, Vixen, and Meade LXD55/75. It also attaches to photo tripods with standard USA or European thread attaching knobs.

Great Scope & Great Value

I picked up this scope from OPT at the SCAE a couple of weeks ago and I am very happy with my purchase. I have mounted it on my CGEM and in my opinion this is the right set up. The mount handles the scope very well, with no strain on the mount when propperly set up. The build quality is exceptional at this price point, you could pay alot more for a compairable scope but why? I have used the scope several times now and have found the views very pleasing and no C/A anywhere. The views of the moon and other very bright stars are pin-point sharp and false color free. Splitting double stars and seeing the true colors is very cool and M5 looks like a dandylion flower in the sky. Also when I got it home and unpacked it there was an added bonus of a 2-25mm eyepiece included that was not listed in the included items, a nice touch. I met Scott Roberts of Explore Scientific at OPT that day as well and he was very happy to spend some time with me going over the features of the scope. All in all, this scope is a great value. The build quality, features, the ATA style case and the on-going relationship with OPT add up to much more than the purchase price of the scope. Clear Skies, Bob

The ES 127 is a Great Scope

When I picked up my ED127 APO the box was nicked, as perhaps a fork lift or machine might make. I asked the agent at UPS to document this in the event that there would be a problem. There wasn't! Alignment was spot on. Upon opening the box, I was flored at the quality case, packing, and general eye appeal of this scope. Now having a chance to use it several times, I can readily say that this ES 127ED delivers. You could spend double for a high end 5 inch refractor, but you really don't have to. You got it all here. Kudos to Scott and crew for designing a top-notch product.

127 APO arrived in solid case, packaged well except for dewshield area which arrived slightly scratched. Still waiting for OPT or ES to replace diagonal fastening screw which arrived bent due to shipping. Views are super thus far!!! No color around lunar rims, edges. Sharp stars all the way to the edges (which surpasses my WO80mm APO doublet. Sturdy construction and very solid, metal objective glass cover. Good value and a scope to pass down through time.
