Description

Ideal for visual observation as well as prime focus, eyepiece projection, and afocal imaging astrophotography techniques, the Vixen Optics SD115S 115mm f/8 ED APO Refractor Telescope has the largest aperture and longest focal length in the series, boosting its light-gathering ability and magnification potential up from the smaller models—making this an ideal optical tube for any astronomer or photographer who wants to view and photograph the moon, planets and deep sky objects.

Optically, Vixen outfitted the SD115S with FPL53 extra-low dispersion (ED) glass, in a fully multi-coated apochromatic lens system that corrects for both spherical and chromatic aberrations, astigmatism, and off-axis comas. This correction creates a wide flat field of view without distortion and removes the blue-tinted halo effect for true high-contrast color transmission. It can accept both 2" and 1.25" eyepieces and accessories for visual use, and threads on the drawtube allow direct connection of T-rings and other camera mounts.

Included with the the optical tube assembly (OTA) is a flip-mirror diagonal with dual 1.25" holders. The light path can be directed to the upper holder with the mirror in the Up position, and to the rear holder by flipping it down. For visual observation, the mirror can hold two eyepieces to allow easy changes from low to high magnification. When using it for imaging, the camera or imaging system is placed in the back, and an eyepiece can be attached at the top to check alignment and tracking between exposures.

Vixen offers the OTA without a mount and tripod for users who already have a reliable support system, but include a mounting ring assembly and a Vixen-style dovetail plate to make it compatible with a wide variety of mounts. An integrated carry handle makes set up and break down easier and safer.

Optical Tube

Designed to capture the entire field of view of a DSLR camera with a full-frame image sensor
Large 115mm aperture draws in enough light to view the moon, planets, and deep sky objects
Fast f/8 focal ratio makes it ideal for long exposure astrophotography and imaging
Long 890mm focal length produces a high magnification potential for viewing and imaging near and deep-sky objects
Refractor-style light path delivers clear and sharp image
FPL53 extra-low dispersion glass corrects chromatic aberration across the entire visual spectrum for clearer views and images without halos or fringing
Apochromatic lens configuration eliminates spherical aberrations that cause distortion at the edges of the field of view, and further corrects chromatic aberrations
Anti-reflection multi-coated optics improve light transmission to produce bright and clear high-contrast images with accurate color fidelity
Resolution: 1.01 arcsec
60mm and 42mm adapter threads accept T-ring and camera mounts for astrophotography and imaging
Rack-and-pinion focusing mechanism; focus lock ensures images remain tack-sharp during long-exposure image capture
2" and 1.25" visual back for eyepieces and accessories

Mounting

Optical tube assembly only — mount head and tripod required for proper use
Vixen-style dovetail plate is compatible with a wide variety of mount heads
Tube rings enable the OTA orientation to be adjusted for proper balance and to avoid interference with mount and accessories
Integrated carry handle for a secure set up and break down
Weight: 13.5 lb

Included Accessories

Flip-mirror diagonal:

Flip mirror down to direct light straight back or move it up to use upper holder
