Product information "Vixen SD103S apochromatic Refractor"

A new apochromatic refractor with high performance Super-ED glass (= SD). The FPL53 glass reproduces an extremely clear and sharp image by an exceptionally high degree of elimination of residual chromatic aberrations. The advantage of these SD refractors is their short length and low weight. The SD glass is designed to bring all beams of violet, red, blue, yellow and green very precisely together on the same plane. The special lens material, reduces chromatic aberration across all colors. In combination with the new optional SD Reducer HD Kit or SD Flattener HD, these refractors allow illumination with a 44mm image circle for full format SLR cameras.

Vixen SD Reducer HD Kit

High-performance flattener and reducer set connection rings for Vixen telescopes SD81S, SD103S and SD115S, as well as the ED predecessor series. High-performance flattener and reducer set The kit consists of a high-performance flattener, a reducer for reducing the focal length, and connection rings (distance ring SD81, EX Tube 66), which were developed for prime-focus astrophotography with the SD81S, SD103S and SD115S telescopes. The flattener and the 0.79x reducer deliver a significant increase in telescope performance and image quality. You obtain a flat and sharp image until the edges, including with a full-frame DSLR camera. Ultra-sharp image over the entire field of view of the DSLR full-frame sensor The SD flattener improves the image quality to the edge of the field of view without changing the original focal length of the telescope. The field of view of the DSLR camera with a full-frame sensor is fully illuminated (44 mm), ensuring that stars appear sharp until the edges of the image. When used in conjunction with the Reducer HD, the focal length is reduced by a factor of 0.79 (f/7.7→6.1) whilst maintaining the 44 mm illumination. High-contrast AS coating The anti-reflex AS coating, which is also used on our high-end VSD 100 f/3.8 astrograph, delivers a high light transmission of 99.9% per lens surface. Loss of light, ghosting and scattered light images are virtually eliminated thanks to the completely matte interior coating.

A redesign by Vixen uses new tougher materials for a more solid connection and also offers an accurate, well-machined camera rotator ring, in order to help frame your images perfectly. Camera-Adaptor for Canon EOS with 60mm Focuser connection thread Large inner diameter for full-format cameras, helping to minimise vignetting 6 locking 60° spaced bolts to hold the camera’s rotation in position Dimensions: 81mm x 30 mm / weight: 190g The option of using 6 long or 6 short fixing screws for the rotator The Vixen 60DA Focal adaptor connects your Canon EOS DSLR Camera to a telescope with an appropriate 60 mm Focuser Drawtube Thread. Thanks to the use of new materials and an improved design Vixen was able to considerably uprate both precision and durability, when compared to conventional rotational camera adaptors. Two sets of rotational locking bolts (Long and Short) are supplied. The longer ones are knurled and easy to turn by hand. The shorter options help to prevent marring of the camera casing, when using certain designs of camera and are also much less easy to turn by hand, increasing security if you need the camera locked in a particular rotational position for longer periods. The large inner dimension of this adaptor prevents vignetting at the edges of the image when using full frame DSLR cameras. Canon EOS-Bayonet fastener made of hardwearing brass, for years of hassle-free use. Increased material quality over conventional adapters provides more stability in use. 6 fixing bolts hold the camera in rotational position for increased sturdiness (standard rotators often only use 4, or less). FEATURES Screw tips with Delrin-tips prevent tilting of the camera and subsequent image distortion. Large inner diameter prevents vignetting. Inner blackening suppresses scattered light. Compatible with 60 mm accessories, when the camera adaptor is taken off. Two rotational bolt sets (Long and Short) are supplied. SCOPE OF DELIVERY 60DA Focal adaptor 6 long and 6 short fixing screws

Vixen SG-L02 Headlamp red-light white-light

The perfect LED head torch for nighttime observations! Adjusting your eyes to the dark surroundings is very important when making astronomical observations. In dark areas, it is very difficult to use astronomical equipment without a suitable light. With normal lights, however, the light intensity is more important than protecting your eyes against bright light. Using these lights at night makes your pupils contract, which can make it difficult for your eyes to readjust to the darkness. The SG-L01, our first astronomy LED lamp, featured a built-in red LED that provided a solution to this problem. However, the red light did not offer optimal visibility. On our new astronomy LED light, the SG-L02, the LED lights produce warm light to improve visibility. They also ensure that your eyes stay adapted to the dark. The LEDs do not emit light in the sensitive range of 555 nm. The brightness of the white light can be adjusted between 3 and 42 lumen, while the red light can be adjusted between 0.28 and 7.62 lumen. FEATURES Dimmable red light ensures that your eyes stay adapted to the dark Built-in rechargeable battery, charges via USB Waterproof design LED colour can be switched from red to white 0.28 to 7.62 lumen for red light 3 to 42 lumen for white light Dimensions: 41 mm x 33 mm x 30 mm Weight: 29 g DELIVERY CONTENT SG-L02 head torch Strap (size S) Strap (size L) Pocket clip Cable for charging the battery (USB-A plug to USB Micro-B plug)

The FPL53 glass reproduces an extremely clear and sharp image by an exceptionally high degree of elimination of residual chromatic aberrations. The SD glass is designed to bring all beams of violet, red, blue, yellow and green very precisely together on the same plane. The special lens material reduces chromatic aberration across all colours.The new Vixen SD103SII no longer uses spacer plates, which leads to a significantly better image quality, especially with bright stars. In photographic images, no spikes can be seen on the stars, which were otherwise produced by the spacer plates. In addition, you will be thrilled when you look at the moon or the brighter planets and observe the moon craters pin sharp as well as with extremely high contrast. Also look at the ring planet Saturn or the cloud bands on Jupiter. But of course, brighter deep sky objects such as the Orion Nebula or the Andromeda Galaxy can also be observed in impressive detail.In combination with the new optional SD Reducer HD Kit or SD Flattener HD, these refractors allow illumination with a 44 mm image circle for full format SLR cameras. The older ED81SII, ED103S, ED115S refractors were originally developed for visual observers and photographers using APS-C cameras. However, the new SD series is also optimised for use with full-frame cameras through the use of new inner baffle rings. The large 60 mm eyepiece extension also allows heavy cameras to be attached without tilting. Furthermore, the included folding mirror allows comfortable observation even in unfavourable observation situations and additionally offers a T2 thread for connecting a DSLR camera. This allows you to observe in straight line or at a 90° angle. The carrying handle attached to the tube clamps ensures a secure grip when transporting the telescope.

EXPLORE SCIENTIFIC ED APO 127mm f/7,5 FCD-100 Alu HEX

Highly corrected 127 mm air-spaced triplet apochromat (with three lenses) and aluminium tube and a 2.5'' high-precision HEXAFOC focuser. NEW: Now with hybrid viewfinder shoe to accept different viewfinder holders. Apochromats are the ultimate choice in small to medium-sized telescopes: the combination of compactness, transportability, very high image contrast and sharpness together with the possibility to make excellent astrophotos cannot be bested. The advances in glass manufacturing during the last few years have made true apochromats available to more astronomy enthusiasts than ever before. The new Explore Scientific FCD-100 Alu Hex represents another major improvement in this field - the overall correction (colour and spherical) is setting new standards in this price class. The optical design shows a polystrehl value of 0.97 indicating a level of correction that is absolutely top of the line. This excellent apochromat is a very versatile telescope: the fast f-ratio makes short exposure times possible. The high contrast and sharpness of the image provide breathtaking views of large objects like the North America nebula or the Andromeda Galaxy, as well as tack sharp planetary images. The telescope is lightweight and compact - the dew shield slides down the tube to minimize size for transportation. Revolutionary glass and precision manufacturing created a telescope that offers observing joy on the highest level. This does not only qualify this telescope as the ideal travel scope, it is also the perfect choice for fast observations and for astrophotography. The excellent 2,5'' HEXAFOC focuser with 10:1 reduction is perfect for this - the large inner diameter of 65 mm prevents vignetting by the focuser when the telescope is used for astrophotography with large sensors.
