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. FEATURES Reduces the focal length by a factor of 0.79 Designed for full-frame cameras High-contrast AS coating Ultra-sharp image over the entire field of view Designed for full-frame DSLR cameras Illumination: 44 mm Correct distance to chip: 63.5 mm Designed for the SD81S, SD103S and SD115S Also suitable for the ED81S, ED103S and ED 115S DELIVERY CONTENT SD Flattener HD Reducer HD Adapter ring for SD81 66 mm EX extension tube Dust caps

High power eyepieces (e.g. 3mm to 10mm) are used not only for obvious observations of planets and double stars, but can be employed for bright, compact deep sky objects. Not only will the scale of an object like a planetary nebula or globular cluster be impressive as it fills the eyepiece FOV, but the background sky will be very dark as the contrast effect increases with added magnification, provided that the atmospheric seeing conditions are favorable enough to reveal a sharp image. The 6.5mm is a popular choice for a wide variety of telescopes, producing some of the highest magnification views that most astronomers will observe at.Comfort, Quality, Value. The Explore Scientific 52° LER Series Most short focal length eyepieces are excellent flat-field multi-element oculars that can transform your visual astronomy experience. With an apparent field of view of 52 degrees, these eyepieces offer incredible value in a very nice eyepiece. Expect exceptional quality and value versus a comparably priced Plossl.  These eyepieces are the choice for observers wearing glasses - with excellent performance and durability. The rubber inlet and the foldable eyecups make handling and using in the field easy. The patented EMD-coating produces high contrast images and prevents reflexes and ghosting. The argon purging effectively prevents internal fogging, and you don´t have to deal with dirt, fungus or cleansing fluids getting between the lenses. The eyepieces are sealed - this makes sure you will be able to enjoy these eyepieces for many years to come.SPECIFICATIONS:Large eye distance, large field and great image sharpnessExcellent viewing position for people with glassesExcellent field sharpness even with fast optics52° apparent field of viewArgon-purging prevents internal fogging, the sealing facilitates cleaningPatented EMD"-coating to maximize contrastBlackened lens edges to avoid reflexesAll eyepieces of this series are parfocalStainless steel barrel with conical security cutoffDust covers and protective bag includedSCOPE OF DELIVERY:52° EyepieceDust coversProtective bag

This extension tube extends back focus depth to an additional 66 mm, for Vixen 60mm diameter focusers. It is suitable for extending compatible focuser drawtubes for use visually without a Star Diagonal but most commonly extends focus travel for astrophotography in a prime focus position, or for straight-through use with Barlow lenses and other accessories. FEATURES Compatibility: all Vixen OTAs with 60mm diameter drawtubes Weight: 115g SCOPE OF DELIVERY Extension tube 60 mm

A new 81 mm apochromatic refractor with high-performance Super ED glass (= SD). The advantage of these SD refractors is their short length and low weight.The FPL53 glass reproduces an extremely clear and sharp image due to an exceptionally high elimination of residual colour errors. The SD glass is designed to bring all rays of violet, red, blue, yellow and green together very precisely on the same plane. Thus, the special lens material reduces chromatic aberration across all colours.The new Vixen SD81SII no longer uses spacer plates, which leads to significantly better image quality, especially with bright stars. This means that there are no more spikes on the stars in photographic images, which were otherwise produced by the spacer plates. You will be thrilled when you look at the moon or the brighter planets and observe the moon craters pin sharp and with an extremely high contrast. Observe 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 impressively.In combination with the new optional SD Reducer HD Kit or SD Flattener HD, this refractor allows illumination with a 44 mm image circle for full-frame SLR cameras.The older ED81SII, ED103S, ED115S refractors were originally designed for the visual observer or the photographer using APS-C cameras. However, the new SD series has been optimised for use with full-frame cameras by inserting new inner baffle rings.The large 60 mm focuser allows heavy cameras to be attached without tilting. The supplied flip mirror allows comfortable observation, even in unfavourable observation situations, and also offers a T2 thread for connecting a DSLR camera.Thus, observing in degree view or at a 90° angle is possible. The carrying handle attached to the tube clamps ensures a secure hold when transporting the telescope.FEATURESObjective Lens: D=81 mm, multi-coated 2-Lens SD Apochromat without spacer plates No more spikes on the stars Focal Length: 625 mm (f7.7) Resolution and visual limit: 1.43 arcseconds; 11.3 Mag Light gathering capacity: 134x unaided eyesDimensions and weight: 90 mm dia x 585 mm, 3.6 kg Finderscope: XY Red Dot Finder II Adapter and connections: Adapter thread 60 mm and 31.7 mm for T2-ringConnection 50.8 mm and 31.7 mm socket with flip-mirror diagonal mirrorPhotography: primary focus and eyepiece projection SCOPE OF DELIVERY Refractor telescope SD81SII Tube rings Flip mirror system Carrying handle Dovetail rail Red dot viewfinder
