Vixen A80MF Refractor£159.00 Back in stock, limited quantity!
The Vixen A80Mf is an Achromatic Refractor with 80 mm (3.2") of aperture. Its focal length is 910 mm with an f-ratio of 11.4. Its light gathering is 130 times better than the human eye and has a maximum (realistic) power of 144x. It weighs about 5.5 lbs. Ideal for use as a guidescope or grab-and-go observing when mounted on a Vixen Mini Portamount.
|  | | Vixen AX 103S Flat Field APO Refractor£2,590.00 "...what makes this scope special compared to most other refractors is that it has a rear field-correction lens as well as its extra-low dispersion, apochromatic, multicoated 4-inch triplet objective (main) lens.The rear lens corrects a problem common to normal refractors, the views of which suffer from ‘field curvature’. This is when light passing through the edge of the lens is brought to focus closer to the lens than light passing through the centre, so image quality drops off towards the edge of the field of view." Steve Richards writing for BBC Sky @ Night magazine (Feb 2010) | | | Vixen ED 115S APO Refractor£2,490.00 This impressive Japanese-made refractor features a Vixen doublet objective that includes a Japanese-Ohara FPL53 ED element for enhanced colour correction and a sturdy 2-inch dual-speed Rack & Pinion focuser. "The Vixen's optics were excellent. The scope corrected false colours almost perfectly when in focus and showed just a little red and green fringing when out of focus. Pointing the scope at the stars showed the optics were pretty much perfectly corrected." BBC Sky @ Night magazine

Vixen ED80SfPlease Contact Us The Vixen ED80Sf is an excellent choice for astrophotography and for grab-&-go visual use. The doublet objective features an ED element from Japanese Ohara FPL-53 extra-low dispersion glass for very low chromatic aberration. | | | Vixen NA 140 SSF Flat Field Refractor£1,300.00 The Vixen NA140mm SSF Flat Field Neo-Achromat refractor employing a fast f5.7 4-element Petzval-like optical design. The rear element enables a normally slow f-ratio objective lens (with lower chromatic aberration) to achieve a faster f-ratio and a flat field.
Whilst not a true Apochromat this fast large-aperture telescope is a very good choice for those using large sensor CCD cameras for high quality narrow-band astrophotography, without requiring a field flattener. | | | Vixen VC200L£1,495.00 The Vixen VC200L is a 200mm f9.0 well-corrected, specialised telescope for astro imaging. Vixen's unique catadioptric design features a high precision sixth order aspherical primary mirror, a convex secondary mirror and triplet corrector lens. The primary mirror is held by a retaining ring, instead of hooks, to decrease flare and enhance contrast. |

Vixen VMC110L£195.00 - £324.00 Also available as a package with Mini-Porta mount and 8mm & 15mm NPL eyepieces.
Ideal for quick and convenient terrestrial observing or grab-and-go astronomy. | | | Vixen VMC200LPlease Contact Us The VMC200L is a 200mm catadioptric optical tube. The use of a meniscus corrector in front of the secondary mirror means that light is corrected twice on the optical path. The result is that spherical aberration and field curvature are well corrected. The VMC200L’s primary mirror is f2.5 and the compound optical system is f9.75 making the system much more compact and portable than many competing models. | | | Vixen VMC95L£195.00 The VMC95L is a 95mm aperture modified Cassegrain f11 optical tube assembly weighing in at under 2kg, it features an integrated flip mirror allowing for swift changing between different magnification eyepieces or an eyepiece and a camera. An excellent travel scope for astronomy. Adding a 45° erect image diagonal turns the scope into a perfectly capable terrestrial telescope for watching wildlife or shipping observation. |
