Since a sandwich mirror cools far more rapidly than a solid mirror of the same thickness, this major source of distortion is eliminated quickly, giving you sharp and stable views. The heaviest component of the UL14 is the primary mirror, which weighs in at about 16 pounds, and the entire telescope is only about 48 pounds, which is remarkably light for a 14-inch telescope. Sorry, but It is not an option for UL14. This fine adjustment allows for critical focusing during high power visual observing or for imaging applications. The mirrors were moved 4.25 inches further apart than on the first two designs. Results will vary according to observing conditions and other factors. Free shipping when ordered with the system. Special Notice-We want to let our customers know that during this timeframe we continue to do business as usual.

Completed with deluxe and environmentally friendly black powder coating, it is such a pleasure to look at, not to mention the enjoyment to look through. 800-483-6287 Also, thanks to John Pratte for his excellent work on the mirror cell, spider, and truss pole bundle. The smaller stainless steel focus control adjusts focus at a rate 8 times finer than the larger focus wheels. Sign up for OPT news, exclusive offers, and updates on the latest gear! It is a zero-backlash "Crayford-style" design further enhanced with modern "linear bearings" meaning you get a rock-solid, super smooth focusing experience that can handle the weight of even the heaviest of modern eyepieces. CONICAL CROSS-SECTION. Add description, images, menus and links to your mega menu, A column with no settings can be used as a spacer, Link to your collections, sales and even external links. The deep red illumination can be adjusted for brightness. The Best Dedicated Astronomy Cameras for Beginners. The three-point collimation system is completely independent from the sling lateral support. It didnt take me long to decide I need to upgrade to a 12 inch … Modular and Compact Design: The Hubble UL14 is delivered in several preassembled modules. It translates to 5% more optical surface and light gathering power than any other 14” scopes in the market. [email protected], © 2020 OPT Telescopes. The UL14 collects 36% more light than a 12" and 96% more than 10" optics, allowing you to resolve significantly fainter objects and more subtle details. Hubble sandwich mirror’s open core and close back design not only allows air to circulate through the mirror, but also provide the maximum structure strength to allow a simpler mirror cell design. We manufacture telescopes and accessories such as telescope wheels, carrying cases, guiding computers, focusers, motors and motor controls and much more. As can be seen on the above photo, all the electronics, the computer module, the power pack, the vertical axis motor have to fit on the 4 inch … We will be glad to help. Read our 101 article or get in touch. In a simple pivoted bolts collimation system, the collimation of the primary mirror may cause the sling belt to pull the mirror axially on the mirror edge, bending the mirror to a potato-chip shape, causing annoying astigmatism. Optical quality : Diffraction limited++ (Strehl 0.95+ for the primary mirror, 1/10 lambda or better in PV for the secondary mirror), Focuser: 2" dual-speed linear bearing Crayford, Secondary mirror obstruction by diameter: 19.7%, Secondary mirror obstruction by area: 3.9%, Mirror coatings/over-coatings : 96% Enhanced coating on both of the primary and secondary mirrors. It features a real mirror cell and mirror box for safe mirror protection, convenient storage and easy transportation.

Matthew Nelson (left) and colleague with a UL24 at the NASA MU69 mission in 2017, UL18 on the Cover of Astronomy Technology Today, Hubble Optics contributed a 40" Hubble Sandwich Mirror to the NASA SpaceX Falcon9 CRS-11 mission. 14" Optical tubes also make exceptional light gatherers by allowing an observer to see 16.5 magnitude stars! Our sandwich mirrors reach equilibrium extremely fast, and without any external disturbing aid. A top quality 50mm achromatic finder offering an inverted and reversed image, perfect for Newtonian Telescope. The optimal 96% enhanced coating has multiple over-coating of precision controlled dielectric layer to maximize the reflectivity and provide excellent chemical and mechanical protection for the mirror coating. The main issue is "mirror seeing," the turbulence seen through the eyepiece of the telescope when the air above the mirror is different from the mirror itself. The UL14 has an extensively modeled and optimized 6-point flotation system that provides more than adequate support for the sandwich mirror. All Rights Reserved.
