Taurus T400 16″

T400 is a proposal for astronomy enthusiasts with high expectations. A powerful mirror with a diameter of over 40cm collects huge amounts of light, producing very bright images, full of details even at low magnifications. Telescope it's ideal for observing deep sky objects, like distant galaxies and nebulae. Openwork construction is designed to be as light and as small as possible, at the same time provide good protection for mirrors. The bottom cell with the primary mirror, which is the heaviest element of the telescope, weighs 18.5 kg. The special designed floating mirror holder with 18 support points and a support belt provide perfect conditions for the mirror in every position. Short focal length makes it possible to perform 100% observations while standing directly on the ground. With no extra steps. Telescope is available with two optics versions:

T400 F/4.5 Classic -  - Optical quality is 1/4 (Standard) or 1/8 (Professional) P-V. Metallic-dielectric enhanced aluminium coating with increased efficiency at 96%.

T400 F/4 Orion Optics series - mirrors from Orion Optics UK with HiLux coating(97% of reflections). Offered in 4 grade quality - from 1/4 down to 1/10 P-V. Supplied with full Zygo interferometer report.

Features of the Telescope:

Compact, light construction. Heaviest part of the telescope weights only 18 kg. After dismantling the telescope fits into trunk of a city car. Telescope encourages to further ventures beyond city agglomerations, in search of dark sky.  

High quality optics. The professional mirror was made with an amazing accuracy of at least 1/4-1/10 labmda P-V and 1/40 RMS. Made of relaxed SUPREMAX® 33 glass by SCHOTT or N-BK7. Optionally a float glass. Hardened coating with increased efficiency 96% or 97% (Hi-Lux - Orion Optics) quarantees high efficiency of a whole optics setup. OOUK mirrors are available with full Zygo interferometer test report. More information at t Optics.

Original design. Combination of modern materials and classic wood makes this telescope an evergreen. It is not only capable of providing great images but also presents itself splendidly. All elements made in CNC technology, handmade finished and assembled with the highest precision. Wooden elements made of waterproof plywood covered with several layers of varnish.   

Optimal mirror cell. Even a perfect mirror will not provide good quality images if not properly fitted. We use 9, 18 or 27 point covers in our telescopes, which providing ideal weight distribution of the mirror.Nylon lower and side supports hold mirror securely and do not cause astigmatism. In horizontal position the mirror rests on a special belt in order to distribute its mass equally. Side hold provided by 3 strong grips. Secondary mirror fitting provided with a separator which prevents tensions. More info

Innovative curved spider. A telescope may be provided with a double-vanes curved spider. Such a solution eliminates problem of so-called diffraction pins - the starts are presented as point-like items. In addition it enhances contrast of planets and visibility of delicate details with low contrast. 

Comfortable usage. Dismantling of the telescope is very intuitional. One person may easily dismantle the telescope within a few minutes. All winders are fixed into the construction. There is no possibility of loosing one of them. Additionally provided with a systemic solution that simplifies  unscrewing (particularly useful when using thick winter gloves). During transportation individual elements are fastened one another, creating a tight chunk, which facilitates relocation and secures construction and optics. Teflon pads and bearing mounting base provides smooth and precise handling even at high magnifications. The mounted base has a rotational resistance adjustment, so you can adjust the telescope to your preferences. A gust of wind or accidental hunch will not move the telescope. The top cell can be mounted in two positions by changing the position of the focuser. This allows for convenient observation from the zenith to the horizon. The telescope is designed, so that the main mirror moves as close to the ground as possible, so that the maximum height on which the eyepiece is located is only 168 cm. This allows comfortable observation without using additional steps or platforms.

Regulated maximum load. The telescope is balanced for oculars up to 1-2 kg. However, in need for fitting of additional accessories the centre of gravity may be moved, increasing  thereby the maximum load. Optionally the telescope may be equipped with a set of counterweight.

Truss  The whole grate is made of 6063 aluminum. Properly selected diameter and cross-section of pipes guarantee high rigidity of the structure. Specially designed pipe ends connected with A2 stainless steel bolts show great resistance to wear and no backlash for many years. All elements are connected together to form a single piece which facilitates and significantly accelerates assembly. The built-in stops do not allow the truss to spread too much and tip over. Connections to which the upper cell is screwed are made of brass.

Comfortable collimation. Each telescope requires collimation from time to time. We have made our best to ensure that it would be as simple and comfortable as possible. No tools are required for collimation. Everything is carried out with comfortable winders placed on the top. Due to applied springs there is no need to counter the settings. Additionally, the main mirror is provided with a central marker for even more precise collimation.  

Solid composition. Details made of strong aluminium 6063, powder coated. All screw joints, bearing bedding in the bottom - made of stainless steel. Wooden elements made of waterproof plywood which allows for the whole construction of the telescope to be fully resistant to atmospheric conditions - moisture, low temperatures or ice.
