    Reveal celestial wonders like the desolate beauty of the lunar terrain, the serene structure of Saturn’s rings or the brightest deep sky treasures of the Messier catalog with Explore Scientific’s ED127-FCD100 Air-Spaced Triplet in lightweight Carbon Fiber!

    This telescope has all the great features of the original EDT-127075-CF but includes genuine HOYA’s premium FCD100 ED glass which is very similar in characteristics as OHARA’s FPL-53. Relying on technological innovation, we have successfully launched the mass production of high-performance optical glass at the apex of the FCD family. Combining it with optical glass of high refractive index allows us to achieve unprecedented advanced chromatic aberration correction. HOYA FCD100 is considered one of the premier ED glass types available.

    Having a true diffraction-limited optical design and sized to encourage spontaneous stargazing sessions, this high-quality telescope is a perfect grab-and-go instrument for exploring the skies. Featuring an air-spaced triplet optical design that virtually eliminates chromatic aberrations, this telescope generates brilliant high-contrast images by combining genuine HOYA FCD100 extra-low dispersion (ED) glass and proprietary EMD enhanced multi-layer coatings on all optical surfaces.

    In addition, this amazing scope also includes a new 2.5" Hexagonal focuser with very rigid design and strong support. Up to 10 lbs of gear can be loaded onto this focuser.

    Delivery Times

    You can estimate the deliver time to your home or business by viewing the "Ships Within" information listed with every product. This refers to the time from when you place your order, to the time it leaves the warehouse. The total delivery time for your order is calculated from the time your order is placed, until you receive it. The diagram below shows how the total delivery time is broken down into pre-ship processing time and shipping time. 

    Processing time is the time it takes from when you submit your order to when the product leaves the warehouse. The "Ships Within" time frame listed with each of our products on the website applies to this time frame. For example, if your order a product that reads "Ships Within: 2 Weeks", this means that the product typically leaves the factory within two weeks. If there will be any additional time required to process your order, we will notify you immediately to confirm the delivery period. This time is needed for products that are shipped to you directly from our manufacturers. The manufacturers need this time to fulfill your order. In some cases, the items are custom built.  Shipping time is measured when your order leaves the warehouse to when it arrives at your address. Actual shipping time can vary between 2-5 business days.

    First Light Skygaze Optics' ED127CF-FDC100


    I cannot thank you and the Skygaze crew enough for the wonderful service, quality, attitude, delivery, and mission statement of Skygaze Optics. Exemplary in its scope (no pun intended).

    I managed to get out one night (before leaving on my one month service hiatus tomorrow) and image NCG7317 - Stephan's Quintet. I have attached a (heavily cropped) copy of the image. I used Star Tools to process the image that was captured and stacked in Nebulosity.

    I need more experience in imaging to reduce the large stars. And more experience in Star Tools to better process the stacked image, but the initial result are encouraging after two years of frustration...(long story).

    Thanks again and I hope you enjoy the image,
    Dan Walters
