Vixen R200SS newtonian reflector with Extender PH 1.4x F/5.6

Kit composed by the Vixen newtonian reflector R200SS and the Vixen Extender PH 1.4x that takes up focal ratio to F/5.6. Corrector is optimized for full-frame sensor delivering a corrected image circle up to 44 mm. Vixen AS Coating for maximum light transmission and maximum stray-light protection!

Vixen R200SS newtonian reflector telescope

The Vixen R200SS newtonian reflector telescope is an high quality reflector with a primary mirror of 200 mm diameter and 800 mm focal length, F/4 focal ratio. The high quality optics and construction from Vixen allows this instruments to be a perfect visual and photographic telescope, perfect for low brightness deep-sky objects such as nebulae, galaxies, open clusters and comets.

The Vixen R200SS newtonian reflector is the reference instruments for astroimaging of the deep-ksy objects with DSLR and CCD cameras up to full-frame format (24x46 mm).

There are a lot of good reasons why you should buy a Vixen R200SS:

• Highest quality optics, superior precision than most of the other competitors;La precisione di lavorazione delle ottiche è superiore a quella di altri newton concorrenti;
• The low focal ratio F/4 allows fast imaging with high signal-to-noise ratio;
• Seconday mirror and low-profile focuser sized for a bigger, unvignetted and illuminated field of view;
• Secondary mirror support with thick spider vanes in order to avoid flexures during long exposures;
• Thank to the use of lighweight material, Vixen was able to make amazingly low-weight yet hogh-quality OTA that even a small mount could carry without problems.

For the best imaging performance, Vixen developed an optional corrector with Wynne optical design able to fully correct largest sensor up to full-frame format (24x46 mm)

The example images show what is the R200SS is capable of: you can see some pictures taken with this instruments and a Canon 350D DSLR with the discontinued V3 Coma Corrector (images courtesy M. Zorzenon).

Vixen Extender PH 1.4x for R200SS newtonian reflector

The Japan made high quality extender lens system for astrophotography, applicable to parabolic mirror newton reflector R200SS turning into F5.6 astrograph.

This product is applicable not only for photography, but also for visual observation.

Features of the Extender PH

• The extender PH kit is designed to extend a focal length to 1.4x. The R200SS Newton reflector of 800mm (F4) will be extended to 1,120mm (F5.6).
• Using optical system of 4-element in 3-group, coma-aberration is extraordinary eliminated to capture sharp images to the edge of imaging field, while complying full-frame camera in 44mm image circle.
• Use of the 31.7mm eyepiece in combination with eyepiece adapter allows visual observation.
• The same anti-reflective AS coatings, which are used for our high-end VSD100F3.8 Astrograph, are used to take advantage of 99.9% superb high transmission of light per lens surface. Loss of light, ghost and flare images are eliminated substantilly due to the complete matte finish inside.
• The use of 50.8mm eyepiece adapter with the extender PH kit enables a use like high performance barlow lens for visual observation while eliminating coma aberration over the entire viewing field.
