Vixen SD115S TelescopeVixen SD115S Telescope - Shown with eyepieces sold separately.
The largest aperture model of the SD series yet still compact at 940mm long and weighing under 6.5kg making it suitable for portable observation set-ups.
The Vixen ED refractor range has been redesigned in order to allow the use of full frame DSLR camera sensors and yet are still compact and portable. The range is now designated SD (standing for Super extra low Dispersion glass) and includes the same 81mm, 103mm and 115mm variants.
Thanks to an improved baffle system, the incoming light near the edge of field of view has been increased when compared to the previous generation models.
The SD range now has its own dedicated field flattener and focal reducer. These help to deliver pin sharp star images across the field of view of a 35mm full-frame image sensor.
The 60mm visual back on the ED range can accept either an optional extension tube or diagonal to accommodate 50.8mm (2”) eyepieces.
