Caran d´ Ache Caelograph Alpha 45 FP Limited Edition 120 Pen 2013 Product type: Fountain pen Brand: Caran d' Ache Model: Caelograph Alpha 45 FP Nib / Refill: M / 18K white gold Accessories: With original box and guarantee booklet This is the first time that a writing instrument has been linked to the celestial vault, the laws of astronomy and the history of time. The Caelograph limited edition, created by Caran d’Ache at its Geneva Manufacture, stems from the technical excellence and the taste for original inventions cultivated by the in-house artisans. This ingenious instrument was designed for admirers of science and for all those who take the time to stop for a moment to gaze at the stars at a given time and place. Available in three materials and three basic latitudes, Caelograph is equipped with astronomic position functions that are manually adjustable, like historical instruments for measurement and navigation. A silent show of the constellations adorns the body of the fountain pen and roller pen. The light of the stars is symbolised by night blue Chinese lacquer scattered with silver particles and in some versions, set with diamonds. A rare one-of-a-kind variation designed for a seasoned collector has been created in solid pink gold set with 22 diamonds. Its piston ink pump, housed in a golden barrel, is crowned with a diamond. Born of a sense of poetry and rare technical precision, Caelograph revives our ancestral ties with the stars and their role in the development of science and art. Edition Alpha 18 K white gold Platinum-coated trim Per latitude 45°N Comes with: Caran d'Ache Caelograph Alpha Edition 45 N Fountain Pen Caran d'Ache Caelograph 30ml Ink Caelograph Alpha Compass

TS Optics Non rotating helical focuser with M48 connection A true helical focuser like this works like a camera objective - when you turn the focusing ring, neither the lens nor the camera (or eyepiece and diagonal) will rotate. The only motion is in and out. The advantage of this helical focuser is the fine adjustment, possible in part due to the fine pitch of the focusing ring's thread, and in part due to the large diameter of the ring. In the case of this helical focuser, virtually backlash-free movement and graduated markings on the focusers allow repeatable return to the focus point simply by noting the focus position reading. Advantages at a glance no rotation of the diagonal or camera - the only motion is in and out precisely adjustable limitedly self-locking wide focus range: 40 mm 51 mm minimum height, 91 mm maximum height easy adaption to the telescope tube and the camera good solution for telescope or objective self construction M48x0.75 (2" filter) threads at both sides, with all adaption possibilities generous clear aperture of 45 mm also suitable as variable M48 extension 51 mm to 91 mm for the perfect working distance two screws for locking the drawtube Wide focussing range and short length The Helical focuser has a wide focussing range of 40 mm, but it is very short, with a minimum height of only 51 mm. So you can use the focuser on telescopes or telephoto lenses with little space to the focus point, like Newtonians. Accessories This focuser is not suitable for heavy accessories, it will tilt. The main use is with small CCD cameras for planetary photography, 1.25" eyepieces and lightweight 2" eyepieces. Delivery contents Helical Focuser with 2 locking screws

Easier for beginners, certainty for professionals! The completely redesigned and revolutionary collimator version 3.0 for your telescope. The market continues to develop towards short focal lengths and highly sensitive cameras with extremely small pixel sizes. This increases the requirements for a clean telescope alignment. The Ocal collimator is an innovative tool, which facilitates the adjustment in a completely new way. Each Ocal collimator has an internal motor that moves the CMOS chip linearly. Via the software, the focus can thus be ideally adjusted to the individual areas of the alignment. So you can focus on any area in the telescope without touching the setup or imagetrain. Colored centering circles can be selected and adjusted via the included software. The software also controls the line width of the circles as well as the contrast and exposure of the live image. Last but not least, a fade cross can be switched on and rotated via software. In this way, all areas that are important for the adjustment can be brought into focus and concentrically aligned very precisely. With the alignment of the crosshairs, the exact linear alignment of the trap can be assessed. Scope of delivery: OCAL 3.0 Connection cable 2x adapter Closing cap

Masuyama eyepieces are known for their clear and high contrast imaging and velvet black background. The good contrast of these high-end eyepieces is achieved with a special cut, internal diaphragms and the best possible internal blackening. Due to the elaborate lens design, the eyepieces get by with only 5 elements, with good correction at the same time. Despite the large field of view, the short focal length Masuyama eyepieces are highly recommended for planetary and double star observation. At the same time, the eyepieces are of course very nice overview eyepieces for deep-sky observation. The long focal length eyepieces are well suited for finding and observing large area deep sky objects. The eyepieces were developed by renowned optician Dr. Masuyama. Among other things, Dr. Masuyama designed an eyepiece with a focal length of 100 mm, which was used on the historic 60-inch telescope at Mount Wilson Observatory in California. We are pleased to offer you these legendary eyepieces with the latest glass and coating technology. Scope of Delivery: Eyepiece Dust caps
