    Vixen Optics' ED81S 81mm f/8 Apochromatic Refractor Telescope is an ideal optic for both celestial observation and astrophotography. Optically, it is designed with a fully multi-coated, apochromatic super-low dispersion (SD) lens system that corrects both spherical and chromatic aberrations. This correction creates a wide flat field of view without distortion and removes the blue-tinted "halo" effect and off-axis coma for true high-contrast color transmission. The optical tube assembly (OTA) is made and assembled in Japan to the high standards expected from such production.


    The scope can be used for multiple astrophotography techniques including prime-focus, afocal imaging, or eyepiece projection. A traditional rack-and-pinion focuser, with adapter rings, is employed to be able to handle the heavier loads of astrophotography rigs and can accept 1.25" eyepieces and accessories for making visual observations. Vixen includes a flip-mirror diagonal that allows the use of two different eyepieces for observational flexibility, or an eyepiece and imaging system that lets users simply flip the mirror to check alignment and tracking accuracy between exposures without having to touch the imager. While the OTA is offered here without a mount or tripod, a Vixen-style dovetail plate that fits on compatible saddles is included, along with a mounting ring assembly with an integrated carrying handle to make setup and breakdown easier.

    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.
