Vixen Telescope R130S User Manual

R150S/R130S  
GP-Trim  
Wide-Field Pleasures Await!  
· Fully Coated Optics  
· No chromatic aberration  
Newtonian:  
150mm/5.9” @ f/5.0  
Design  
Newtonian reflector telescopes are  
completely free of chromatic aberration,  
and they are generally less expensive  
than refractor telescopes of equal  
aperture. The parabolic mirror reflectors  
have neither chromatic aberration nor  
spherical aberration and their center  
image is extremely sharp.  
Parabolic multicoated mirror  
Vixen’s unique sliding focus mount (for  
the R130S and R150S) has the  
advantage of using a smaller secondary  
mirror that minimizes light loss due to  
secondary mirror obstruction.  
R150S OTA GP-Trim  
The 5.9” clear aperture of the R150S optical tube and  
f/5 focal ratio results in a potent, wide-field photo-  
visual system with 0.77 arc-sec of resolution. A 6x30  
finder and 1¼” eyepiece adapter are included. (Shown  
with optional eyepiece, tube rings and dovetail plate  
on GP-type mount.)  
Optional Photo Accessories  
Model # TS-ON-8696  
Wt: 4.8 kg / 10.6 lbs  
Tele-Extender R130S/R150S  
Tele-Extenders extend the  
effective focal length of the  
optical system. They can be used  
in place of a Barlow lens for  
imaging applications. Extends  
the focal length of the R150S  
from 750mm to 1500mm (f/10)  
and the R130S from 720mm to  
1440mm (f/11).  
Newtonian:  
130mm/5.1” @ f/5.5  
Model # AV-TE-3631  
Focal Reducer R130S/R150S  
Focal reducers shorten the  
effective focal length of  
Parabolic multicoated mirror  
telescopes to provide wider  
visual fields and faster f-ratios  
for astrophotography. This focal  
reducers is for astrophotography  
only. Shortens the focal length of  
the R150S from 750mm to  
652mm (f/4.3) and the R130S  
from 720mm to 626mm (f/4.8).  
Model # AP-FR-3633  
R130S OTA GP-Trim  
Great entry into Vixen quality! The R130S optical tube  
has 5.1” aperture and yields 0.89 arc-sec of resolution.  
At f/5.5 this is great for wide-field viewing and imaging  
of extended objects. 6x30 finder and 1¼” eyepiece  
adapter. (Shown with optional eyepiece, tube rings &  
dovetail plate on GP mount.)  
Model # TS-ON-8695  
Wt: 3.7 kg / 8.2 lbs
